Description
The present invention relates to a kind of method and apparatus that increases combustion gas wheel power, or rather, the present invention relates to a kind of method and apparatus that increases the power that gas turbine produced in the combined cycle ground power unit.
Combined circulation power apparatus is meant that the exhaust that gas turbine produced in this device is used for driving steam boiler, and the steam that steam boiler produces resupplies steam turbine.The power that this combined circulation power apparatus produced is the summation of each turbo-driven generated output power.The method that tradition increases the gas turbine work done is the pressure that reduces the temperature of turbine inlet and increase turbine inlet.The registration number that American Society of Mechanical Engineers is delivered is 65-GTP-8(1965), the author is the paper of RWFoster-kegg, the author has described and has utilized fan that gas turbine supercharging (promptly increasing inlet pressure) is improved the turbine output rate.Because fan operation increases inlet air temperature to the adverse effect of the output power of gas turbine, by being compensated to air ginseng water for cooling air before entering into turbo machine at air.The temperature and humidity of ambient air has been controlled the increase of gas turbine output power, and is verified, and this technology is not effective under sweltering heat, wet condition.
In addition, when ambient temperature is higher,, externally do work so can reduce gas turbine owing to reduce through the MAF of system.Drive in the combined cycle of steam turbine at the steam that utilizes turbine exhaust to produce, this high ambient temperature can further cause reducing of exhaust mass flow, has reduced steam turbine institute work like this.Even so, under the high ambient temperature condition, when using water-cooled condenser,, make influence, obtained the compensation of part the steam turbine ride quality owing to improved delivery temperature.Yet when utilizing air surface condenser, high ambient temperature is harmful to.In this case, because the gas mass flow that turbine is discharged is less, institute reclaims some waste gas so that steamer institute work reduces owing to fuel gas temperature is higher, but, thereby steam turbine institute work is reduced owing to the higher condensing pressure in air surface condenser is preponderated.
U. S. Patent NO.3796045 has described a kind of gas-turbine power plant, in this device, the air of supplying with gas turbine blower makes its increased pressure through a motor-driven fan earlier, and then through a dark cooler, dark cooler is traditional compression-type refrigerating device.The net power that is produced surpasses the net power that does not have precompression and deep cooled gas-turbine power plant in this way.In described another embodiment of this patent, utilize a used heat transducer to make the exhaust heat drive fan and the dark cooler of gas turbine.
On January 8th, 1992 application, application number is the series of patents application of 07/818123 unexamined, has disclosed a kind of improved cooler that the air that will offer gas turbine is cooled off.Employed term in this specification " deep cooling but " is meant ambient air is cooled to the temperature that temperature is significantly less than ambient air.Deep cooling but is meant the cooling of air being carried out in for the power plant on basis at ground gas turbine that typical tradition is used for power is offered electrical network especially, makes air cooling to thinking the minimum temperature value that is suitable for import.For fear of on gas turbine powered main compressor blade, freezing, consider that the temperature drop of compressor inlet place still air temperature is approximately the safe clearance of 10 (5 ℃) and 3 (2 ℃).
Than under the condition with higher, use deep cooling but cost is non-remunerative in relative moisture.For example, in the Florida thirty or, do not use dark cooler and devaporizer, but be very common in the arid region in California in the place of other humidity of east coast of the united states.
Therefore, the purpose of this invention is to provide a kind of by new, improvedly giving compression and heat of cooling technology, giving the method and apparatus that pressurized air increases the gas turbine output power.
The present invention is used to increase the power that a kind of gas turbine engine systems produces, thereby this gas turbine engine systems has one to be compressed the ambient air that is provided and to produce compressed-air actuated main gas compressor, a firing chamber that is used for heated compressed air and produces high-temperature fuel gas, a gas turbine that is used to drive main gas compressor and load and produces high-temperature exhaust air by the high-temperature fuel gas drive.According to the present invention, the increase of power is the pre-gas compressor device that utilizes a precompression ambient air, and an indirect cooled compressed air also produces the cooler of cooled compressed air, and the air of cooled compressed is provided for main gas compressor.Best, a boiler also is set, drive and generation steam by the high-temperature exhaust air that described gas turbine produced.And the steam that best described boiler produced is used for driving steam turbine, so that drive load.The used cooler that has liquid circulation usually replaces compressed-air actuated evaporative cooling, and it is favourable combining with precompression, because it provides a kind of humidity of the air to external world insensitive device.Preferably the working fluid of cooler is safe for environment, for example butane.
Use deep cooling and evaporative cooling meeting that high latent heat load is forced at system in the higher place of humidity ratio, so the cost of this class cooling is non-remunerative.According to system of the present invention, utilizing precompression and cooler almost is best scheme under high humidity.According to the present invention, the pressure ratio that precompression produces approximately is 1.15.
In the present invention, cool off employed temperature range and be different from devaporizer and the dark employed temperature range of cooler.According to the present invention, cooling action reduces to the temperature of precompressed air and is approximately outside air temperature, and evaporative cooling and/or deep cooling are reduced to air temperature the temperature that is significantly less than ambient air.Therefore the present invention does not need malaria is carried out drying, is different from devaporizer and the deep cooled method of adopting, and under wet condition, devaporizer and dark cooler can make cooling load be increased to three times in the method.The present invention has not only improved efficient, and does not need to pay the cost that increases load under wet condition.
When relative temperature when higher, cooling meeting of the present invention is reduced to air temperature the value of a little higher than ambient temperature.In addition, if cost efficient, cooling can be reduced to air temperature the value that is lower than ambient temperature slightly.But,, in combined circulation power apparatus, when air temperature is reduced to the value that is lower than ambient temperature slightly, must consider its consequence according to the present invention.Best, cost effectiveness according to system, be approximately 80% or higher even in relative moisture near 100% place, the temperature of precompressed air can be cooled to be higher than about 5 ℃ of ambient temperature, in the place of relative moisture between 50% to 80%, the temperature of precompressed air can be cooled to be lower than about 10 ℃ of ambient temperature.
The present invention is in the arid region, using the uneconomical feasible zone of dark cooler or devaporizer (for example water source be restricted or polluted zone), also is effective and feasible.Further, according to the present invention, when moving, allow to use cheap heat exchanger under temperature is higher than the condition of ambient temperature, heat exchanger can be with ambient air as cooling medium, and does not use freezing mixture.
In addition, in the present invention, rely on cooling, make that steam turbine institute work has improved in gas turbine institute's work and the combined cycle temperature.As for steam turbine, because being higher than, the fuel gas temperature that gas turbine is discharged use deep cooling but and/or the fuel gas temperature that gas turbine is discharged during evaporative cooling, so there is more heat to utilize.Therefore, steam turbine institute work is greater than using deep cooling steam turbine institute work but and/or during evaporative cooling.This point is correct especially under the ambient temperature conditions of higher, and this is because the fuel gas temperature that chilling temperature scope according to the present invention can make gas turbine discharge is increased to it and do not use the situation when cooling off identical.
And, because the operation of combined circulation power apparatus of the present invention, so that the ambient conditions in the face of changing, under its constant condition (special volumetric flow rate), heat recovery steam generation (HRSC) can appear in power plant.As long as control cooling degree that cooler produced, no matter result's ambient conditions how, the cooler outlet place gives compressed-air actuated temperature it remains unchanged and just can realize fully.This operation allows the design optimization of the heat recovery steam generation of combined circulation power apparatus to become a single substantially point, and like this, operating under all ambient conditionss of power plant still can approach its design level.
By comparing, traditional combined circulation power apparatus is designed to operation in certain condition and range (for example comprising that the MAF pulsation is 30%).Like this, when traditional combined circulation power apparatus is chosen the heat recovery steam generation, must consider to run into all conditions having size and optimizing in the running of otherwise impact.Like this, traditional combined circulation power apparatus all is in operation under the off-design behaviour in the most of the time in 1 year.And according to the present invention the structure of combined circulation power apparatus, determined this device throughout the year substantially in optimum operation, like this, saved 10% design and construction fund, the result has reduced the size of heat recovery steam generation.In addition, owing to improved efficient, therefore also saved operation.
In addition, according to the present invention, under the situation of change of external conditions, gas turbine engine systems is operation under substantially invariable condition (special volume mass flow rate) also.About this point, no matter ambient conditions is how, this can realize by the control cooling degree that cooler produced, the result no matter external world situation how, the temperature of cooler outlet place precompressed air keeps constant substantially.This operation moves gas turbine engine systems under the situation that approaches design conditions point substantially, thereby makes power plant under all ambient conditionss, all moves under the design conditions near it.
Another aspect of the present invention has combustion gas that the power plant gas turbine engine systems of pre-gas compressor device and cooler discharged and can be used for common generation (promptly produce steam for heating with).In this case, under the situation of change of external conditions, system's operation under substantially invariable (special volumetric flow rate) condition is favourable according to the present invention.This point can realize fully that just the temperature of cooler outlet place precompressed air keeps constant substantially as a result by the control cooling degree that cooler produced.Because heat is the industrial process part that needs continuous running under controlled condition.Therefore, this operation is for common generation system advantageous particularly.
The present invention adopts cooling after precompression, this with deep cooling but or evaporative cooling compare, its cost is more reasonable.Cooling after the precompression and deep cooling but (have or do not have evaporative cooling) and carry out cooling raio, when ambient temperature is 35 ℃, can this point be described with figure.By cool off after the precompression, the temperature of main compressor inlet place air will drop in the scope that is about 25-35 ℃ from about 50-60 ℃ scope.And utilize deep cooling (having or do not have evaporative cooling), air temperature will drop in the scope that is about 5-10 ℃ from being about 35 ℃.Utilize precompressed system effectiveness not only high but also cheap.
According to the present invention, precompression and cooling can improve 20-30% with the capacity of system.And output power is insensitive to the influence of local weather.
Further aspect of the present invention, precompression can replace needed heater cold season.In this case, pre-gas compressor can increase the temperature of main gas compressor top inlet place air, prevents from here to freeze.With bright, centrifugal water droplet formula cleaner is set according to this, has avoided like this in pre-gas compressor, producing and freezed by inlet at pre-gas compressor.On the other hand, the import of pre-gas compressor is designed to guarantee that water droplet influences the performance of pre-gas compressor not obviously.The scheme that adds another selection or auxilliary is, a part of high temperature precompressed air can recirculation, with to entering the air heating of pre-gas compressor.Compare more simple by the structure of the air that recirculation master gas compressor is discharged with entering the air of main gas compressor for preheating for this structure.
Further aspect of the present invention is being provided with filtrating equipment between pre-gas compressor device and main compression mechanism of qi, to from the air-filtering of pre-gas compressor device and produce pressure drop in the air that is provided.The arrangement of the structure of pre-gas compressor device, the pressure that makes thus to be produced raise at least greater than the pressure drop that filtrating equipment produced.Further, the cooler that relies on the temperature drop that is produced that the air that is provided is provided is preferably disposed on the upstream or the downstream of filtrating equipment.
Filter used in the present invention since long-time running under relatively near designing quality flow and other designed condition, therefore, its efficient height, the life-span is long.
By means of gas turbine master gas compressor front filter produced relatively the appropriateness pressure drop, be easy to regulate by the gas compressor of a fan type, at the ground installation that is used for providing power to electrical network, an assembly is the sin qua non, these fan type gas compressor Operation and maintenance are simple, and only need less energy to drive.Further, the temperature drop that is fit to relatively that produced of air low capacity cooling can be realized under needs not lose the situation of macro-energy very.
Its temperature of the air of the discharge of pre-compression phase and cooler is substantially near outside air temperature, and its pressure should be high to being enough to compensate the pressure drop that is produced in the filtration that links to each other with gas turbine master gas compressor at least.Moving required total energy can be at an easy rate by steam turbine in the combined circulation power apparatus, for example, is regulated by a part of output power of the steam turbine of the exhaust gas drive of gas turbine.Like this, whole system is compared with existing combustion gas turbine power plant, and its efficient has improved widely, and does not increase expense significantly, and power plant are simple in structure, is convenient to maintenance.

Referring to accompanying drawing, the sequence number 100 expression first embodiment of the present invention, it comprises a ground combined circulation power apparatus.Thereby this ground combined circulation power apparatus has to compress for the ambient air that provides and produces compressed-air actuated main gas compressor 130, heated compressed air so that produce the firing chamber 140 of high-temperature fuel gas, driven by coupling shaft 160 by high-temperature fuel gas and drive main gas compressors and drive the gas turbine 150 of load 170, and load 170 is typical generators.The high-temp waste gas that gas turbine 150 is produced directly is discharged in the boiler 180 that contains water, will water is vaporized into steam by the combustion gas of these discharges, and after this, combustion gas is discharged in the ambient atmosphere through a silencing apparatus (not shown) usually.Then, steam is fed in the steam turbine 181 and expands there and produce merit, and this merit acts in the load 182.The steam of discharging from steam turbine after the acting condenses condenser 183, and the condensation product that is produced is pumped back to repetitive cycling in the boiler by pump 184.
The pressurized air of main gas compressor 130 is provided by the pre-gas compressor 110 that motor 111 drives.The pressurized air of compression process heating is provided for cooler 112, and 112 pairs of air coolings of cooler are reduced to its temperature and are approximately ambient temperature.Cooler can be a part mechanical refrigeration system (not shown), and this system offers cooler with refrigerant.The pressurized air of cooling is preferably first through filter 113 before supplying with main gas compressor 130.Filter 113 is centrifugal filter preferably.
Fig. 2 shows second embodiment of the present invention, and sequence number 10 represented power plant comprise common power plant 11, by install 12 with low capacity give the compression and cooling air offer power plant 11.Large-scale ground power plant that are commonly used to electric power is offered electrical network of power plant 11 expressions.Thereby power plant 11 comprise the ambient air that compression provides and produce compressed-air actuated main gas compressor 13, be used for heated compressed air to produce the firing chamber 14 of high-temperature fuel gas, drive and drive the gas turbine 15 of main gas compressor 13 by coupling shaft 16 by high-temperature fuel gas, gas turbine 15 also drives load 17, and typical load 17 is a kind of generators.The high-temperature exhaust air that gas turbine 15 is produced is discharged in the atmosphere through the sound-attenuating system (not shown) usually.
At the large-scale ground device that is used for producing electric power; the electric power that it produced is supplied with electrical network; filtrating equipment 18 is integral parts of the air supply system of main gas compressor 13, and it is necessary that filtrating equipment 18 is set, and prevents that with the protection gas compressor particle that damages the compressor blade device from sucking.Filtrating equipment 18 produces pressure drop in the process that air is imported main gas compressor, the result makes the air pressure of gas compressor 13 inlets be lower than the air pressure of filtrating equipment 18 inlets.
The pressure that pre-gas compressor device 20 is provided is used for compensating the pressure drop through filtrating equipment produced at least.Device 20 compressions are provided to the ambient air in the main gas compressor, and the air pressure and the temperature that are provided are raise.Term used herein " air that is provided " is meant the air through main gas compressor provided.
As shown in Figure 2, institute's elevated pressure and temperature are represented with △ P and △ T in the pre-gas compressor device.The structure of pre-gas compressor device 20 and to arrange should be such makes pressure rising that this device produces at least greater than pressure drop that filtrating equipment produced.But according to the present invention, the air pressure that is fed to main gas compressor 13 is greater than external air pressure.
Be provided with low capacity cooler 21 between pre-gas compressor device 20 and inlet filter 18, low capacity cooler 21 produces temperature drop △ T for the air that will be provided to gas compressor.Cooler 21 is designed so that this cooler temperature that produces and the temperature that pre-gas compressor device 20 is produced raise big or small basic identical.Because cooler 21 makes the air temperature that enters into main gas compressor 13 usually substantially near ambient temperature.
Replace driving the exterior motor of pre-gas compressor, pre-gas compressor can directly drive by the steam turbine installation that the combustion gas of being discharged by gas turbine is turned round, and for example when using combined cycle, the primary product that steam turbine produced is an electric power.Referring to Fig. 3, power plant 30 comprise pre-gas compressor device 20A and the low capacity cooler 21A that is similar to respective element shown in Fig. 1.But these power plant 30 also comprise steam turbine installation 31.Steam turbine installation 31 comprises vaporizer 32, and vaporizer 32 includes the water as working medium, and the gas driven of being discharged by gas turbine 15 and produce steam.Steam offers turbine 33 by pipeline 34, and turbine directly drives pre-gas compressor device 20A by the lively power of steam zone movable property and by axle 35, and axle 35 directly links together turbine and pre-gas compressor device.Steam expansion acting in the turbine 33, this merit also drives pre-gas compressor device 20A, and steam is discharged to the venting gas appliance 36 from turbine after the acting.In addition as shown in the figure, cooler 21A is also driven by turbine 33.
Be arranged in the steam of the turbine discharge of steam exhaust device 36, condense in condenser 37, the coagulant that is produced offers pump 39 by pipeline 38 thus, and pump 39 is again with coagulant blowback vaporizer, the circulation of the working medium of having maintained the achievements of one's predecessors like this.Condenser 37 is preferably by air cooling, and needed any fan assembly (not shown) can be driven by external motor usually.Utilize turbine 33 directly to drive pre-gas compressor device 20A and cooler 21A, reduced like this and the size of turbine generator coupled (in Fig. 3, representing) and its loss with load 22 through axle 35.
In operating process, ambient air is sucked into preformer device 20A, and pre-gas compressor device 20A raises air temperature and pressure.The air of discharging from pre-gas compressor device 20A enters low capacity cooler 21A, and cooler 21A produces temperature drop, and this temperature drop value approaches the temperature lift-off value that pre-gas compressor device 20A is produced substantially usually.Then, air enters filtrating equipment 18 again, produces pressure drop thus.The air temperature that the result is provided to main gas compressor 13 approaches ambient temperature usually substantially, and pressure is a bit larger tham atmospheric pressure.The air that the compression of main gas compressor is this, and air supplied with firing chamber 14, in firing chamber 14 with fuel to air heating, and will offer the gas turbine 15 that drives load 17.Usually give steam turbine installation 31 from the combustion gas that turbine 15 is discharged, turbine 33 produces power like this, also drives pre-gas compressor device 20A and cooler 21A simultaneously.On the other hand, some electric power that turbine 33 is produced can offer traditional refrigeration system effectively, and this refrigeration system offers cooler 21A with cooling liquid.
In embodiments of the invention shown in Figure 4 40, except precompression and low capacity cooling employing parallel form separately, all the other structures and arrangement and shown in Figure 2 similar.So, pre-gas compressor device is arranged to independent pre-gas compressor 41,42 and 43, they offer filtrating equipment 18A in parallel with ambient air, and parallel filtering device 18A also comprises one group of independent filter 45,46,47, and these filters link to each other with independent pre-gas compressor respectively.In this embodiment, low capacity cooling unit 21A also comprises independent cooler 48,49,50, and these coolers 48,49,50 also link to each other with independent pre-gas compressor respectively.The advantage of structure shown in Figure 4 is that each air filter and pre-gas compressor and low capacity cooler can be loaded onto or remove respectively in the line, and can not influence the operation of power plant 11A.Another advantage of this structure is, making for whole power plant is filtrating equipment simple in structure of a big and expensive component.
In addition,, can use embodiment shown in Figure 4, utilize this embodiment's combined circulation power apparatus can comprise and Fig. 1 and shown in Figure 3 and described similar method according to the present invention.
According to the present invention, adopt the pressure ratio that precompression produced to be about 1.15, cooling makes the temperature of precompressed air reduce to the temperature that approximately approaches ambient air.On the contrary, evaporative cooling and/but under the situation, air temperature reduces to the value that is significantly less than ambient temperature to deep cooling.
Under the humidity ratio conditions of higher, the embodiment of the above according to the present invention, system uses pre-gas compressor and cooler that special advantage is arranged.According to the present invention, do not need very wet air is reduced humidity, in fact, under the condition of humidity, can raise the efficiency.On the contrary, in legacy system,,, under wet condition, can make cooling load become three times increase if at first do not reduce humidity owing to used devaporizer and dark cooler.
Under wet condition, promptly when relative moisture when higher, cooling meeting according to the present invention reduces to the value of being a bit larger tham outside air temperature with the temperature of precompressed air.If but consider actual cost, air can be cooled to and make air temperature be lower than external temperature slightly.Yet, when combined circulation power apparatus uses steam turbine, must consider of the influence of the minimizing delivery temperature that gas turbine produced to the power that steam turbine produced.Best cost effectiveness according to system, relative moisture be about 80% or higher situation under, even under near 100% situation, precompressed air can be cooled to exceed about 5 ℃ of ambient temperature, under the situation between 50% and 80%, precompressed air can be cooled to be lower than about 10 ℃ of ambient temperature in relative moisture.
And then, reach described combined circulation power apparatus as shown in figures 1 and 3 according to example of the present invention, its power plant can move in such a way, under the situation of change of external conditions, under substantially constant condition (special volumetric flow rate), power plant can produce the heat recovery steam generation, this can realize (one of them example is a control gear as shown in Figure 5) fully by the control cooling degree that cooler produced, regardless of ambient conditions, the temperature of cooler outlet place precompressed air keeps substantially constant like this.This ride quality allows the heat recovery steam generation optimal design of combined circulation power apparatus to become single substantially point, makes the ride quality of power plant under all ambient conditionss all approach its design level.
By comparing, traditional combined circulation power apparatus moves (comprising that pulsation is 30% as MAF) in certain condition and range.Like this, the heat recovery steam generation of tradition combined circulation power apparatus must be considered at all conditions that has size and preferably be subjected to may running in the running of otherwise impact traditional combined circulation power apparatus all to be moved under off-design condition the most of the time in 1 year.And according to the present invention the structure of combined circulation power apparatus, determined this device throughout the year substantially in optimum operation, saved 10% design like this and built main fund, as a result, reduced the size of heat recovery steam generation, in addition, owing to improved efficient, therefore also reduced additional operation.
In addition, according to the present invention, under the situation of change of external conditions, gas turbine engine systems can (special volume mass flow rate) move under substantially invariable condition, this can realize (one of them example control gear as shown in Figure 5) by the control cooling degree that cooler produced fully, and the temperature of cooler outlet place precompressed air keeps constant substantially like this.This operation permission gas turbine engine systems operates in substantially and approaches under the design condition, thereby power plant are moved under the situation that is all approaching design level under all ambient conditionss.
In as Fig. 1 and 3 described an alternative embodiment of the invention, have the combustion gas that the power plant gas turbine engine systems of precompression machine and cooler discharged and can be used for common generation (promptly producing steam) as process heat.In this case, under the situation of change of external conditions, the present invention helps system in substantially constant condition (special volumetric flow rate) operation down.This can realize that the temperature of cooler outlet place precompressed air keeps constant substantially as a result by the control cooling degree that cooler produced fully.Because heating is need be in the part of the industrial process of continuous running under the controlled condition, therefore this operation advantageous particularly in common generation systems.
When gas turbine of the present invention or power plant construction apart from natural water resources such as nearer places such as sea, river or lake, or apart from the nearer place of cooling water source of cooling tower and it, the water that comes from above-mentioned water source cools off precompressed combustion gas as the cooling medium of gas turbine indirect cooler.In this case, particularly relate under the situation that the temperature of precompression combustion gas will be reduced near ambient temperature in cooling, because the coolant-temperature gage at above-mentioned water source is lower than outside air temperature, therefore a water air heat exchanger that has mechanical cooler simply, indirectly need be set.
Further aspect of the present invention, when gas turbine of the present invention or combined circulation power apparatus are lower than when moving under the condition of ambient temperature slightly being cooled to its temperature in the precompression combustion gas under the moist situation, in the combustion process that the water that precompressed air airborne water recovery of when cooling is produced adds in the gas-turbine combustion chamber to be taken place, can control the nitrogen oxides in the exhaust like this.Because the water purity that is produced is than higher, therefore the nitrogen oxides in this water management exhaust can be accomplished.
In the arid region, be restricted especially in condition and avoid using dark cooler or devaporizer, for example be restricted to make and utilize evaporative subcooler very costliness or water resources such as are polluted at the zone in the available water resource, embodiments of the invention are also effective, and according to the present invention, owing to require cooling usually to reach more than the ambient temperature, so air-cooler, promptly do not adopt refrigeration cycle and adopt the heat exchanger of usefulness ambient air as cooling medium, can be as the cooler in the such scheme.
And, another aspect of the present invention, the heater that the precompression that pre-in the above-described embodiments gas compressor is produced also can replace cold snap to use, therefore, preformer has improved the temperature of outlet port air, thereby has reduced the chance of freezing in the main gas compressor as best one can.According to the present invention,, the phenomenon of freezing in the pre-gas compressor is avoided because the present invention also comprises mechanical centrifugal water droplet cleaner.On the other hand, the import of pre-gas compressor is designed to guarantee the performance of the pre-gas compressor of the not obvious influence of water droplet.And, perhaps combining with these selection schemes, a part of high temperature precompressed air can circulate, with to entering the air heating of pre-gas compressor.This structure is more simple in structure than the recirculation master gas compressor institute exhausting air in order to heat the air that enters main gas compressor.
Has pressure ratio and is 1.15 the precompression and the embodiment of the present invention of cooling, when ambient temperature is 35 ℃, capacity can improve 20%, and the increase capacity does not almost completely rely on weather conditions, therefore power plant reasonable price proposed by the invention, applicable to most of weather sweltering heats, moist summer be common industrialized country.
By the invention described above most preferred embodiment, had for advantage that apparatus and method of the present invention had and improvement effect to more clearly understand.But, can also make various changes and change without prejudice to the spirit of accessory claim of the present invention with do not break away under the prerequisite of its scope.
