A kind of gas-burning hot-blast machine, it is used for petroleum production and boiler or various heating plants such as petroleum processing, chemical industry and metallurgy, is specially adapted to use at outlying no electricity or power outage area.
Now as used air heater in used boiler such as petroleum production and processing, chemical industry and metallurgy and the various heating plant, mostly be that employing is a power source with the AC motor, drive fan pressurized air air feed, and exhaust heated (introduce hot air, or directly igniting heating in exhaust), send into various boiler equipments then to help burning, to heat or carry out chemical reaction.Because common too much by motor-driven blower fan conversion links, it is not high to drive efficient, need expend a large amount of electric energy, is particularly requiring to change under the condition of operating mode, the efficient of this air heater is just lower.If from generating, consider the utilization ratio of primary energy, have only 10-20% by motor-driven air heater total efficiency so.Therefore air heater is put into one of energy-conservation object of state key.In recent years, there are indivedual departments to adopt converter technique that the motor driving air heater is transformed, use variable-frequency power sources to adjust the AC motor rotating speed, use with the variable working condition of satisfying air heater, reached certain energy-saving effect, can saving power 30%(be equivalent to primary energy efficient and bring up to 14-28%).But, no matter whether use converter technique, all needing to consume a large amount of high quality secondary energy-electric energy by motor-driven air heater, this is inappropriate in some specific occasion.As if the location, oil field generally all away from electrical network, needs generating voluntarily.Be exactly at electrical network areas of coverage such as cities and towns, because power tense, to the such large electricity consumer of air heater, electrical network also is difficult to burden, will the use of air heater be limited usually.Simultaneously, production departments such as oil, chemical industry, metallurgy generally all can produce some flammable waste materials (title industrial tail gas) in process of production, as natural gas, Petroleum refining tail gas, coke oven or blast furnace gas etc.If the hot blast function is electrification and use these industrial tail gas not, that will have bigger energy-saving effect.
The objective of the invention is to invent a kind of gas-burning hot-blast machine that does not need electric energy just can turn round voluntarily, make it have higher primary energy utilization efficiency, and compact structure, easy to use.
Structure of the present invention as shown in Figure 1, it has casing (1), fan blade (2), fan blade (2) is a multilevel hierarchy, stator blade (4) is arranged between adjacent two-stage fan blade (2), in fan blade (2) back gas generator (3) and turbine blade (5) are housed, turbine blade (5) links to each other with fan blade (2) by transmission shaft, it is characterized in that: wherein the first order or a front number grade stator blade are angle adjustables, temperature and pressure measurement cell (6) are housed in the relief opening behind turbine blade (5), and have and link to each other, and the controller (7) that can control the fuel flow rate of the angle of angle adjustable stator blade and gas generator (3) with temperature and pressure measurement cell (6).
In the present invention, casing (1), multistage fan blade (2) and stator blade (4), gas generator (3), and turbine blade (5) constitutes the form of a gas turbine.In when work, fan blade (2) pressurized air also offers gas generator (3) to it.In gas generator (3),, improved the interior energy that is compressed air by spraying into fuel and ignition.After the air that has increased interior energy is discharged, drive turbine blade (5) rotation from gas generator (3).And turbine blade (5) drives fan blade (2) work by transmission shaft.As long as continuous postcombustion, the present invention just can be turned round voluntarily.Realized the working principle of general gas turbine engine.Fan blade of the present invention (2), stator blade (4), gas generator (3), the design of turbine blade (5) and casing (1) all with the gas turbine basically identical, just during turbine blade (5) design, can reduce its absorbed power.
The present invention is in when operation, though the high-temperature high-pressure fuel gas of gas generator (3) output during through turbine blade (5), needs the acting of expanding, discharges energy in the part.But the gas of being discharged also has sufficiently high temperature and very big flow, and this is the required thing as output of ordinary hot blower fan just.Therefore the present invention just in time can use as air heater.
The energy that fuel combustion among the present invention produced except that the heating that has a few part all to pass through casing (1) is dispersed into space outerpace neutralization consumes by the lubricant oil cooling, is used for the heating of air all and has pressurizeed.Therefore it has very high primary energy conversion efficiency, and its efficient can reach more than 75%.The heat release of in gas generator (3), burning of fuel among the present invention, as long as certain proportions of ingredients and combustion condition are arranged, just can smooth combustion.Therefore, it is less demanding to fuel, no matter is liquid fuel or gaseous fuel, even pulverulent solids fuel can.Simultaneously, no matter the height of the combustion value of fuel and the height of burning-point as long as use different fuel delivery systems and nozzle instead, and are suitably adjusted the firing chamber, just can both adapt to and stable operation.Therefore, when different industries such as petrochemical industry, metallurgy are used, can use flammable industrial tail gas separately, reach further purpose of energy saving.
The present invention has used gas generator (3), will consume certain oxygen at work.But because gas generator of the present invention (3) is to be operated in the oxygen-enriched combusting state, and air mass flow is very big, so the decline of the oxygen content in institute's thermal wind exhausting is few, and 17-18% can also be arranged.The oxygen content of the air heater institute thermal wind exhausting that this and common use burning are heated is basic identical.Simultaneously, because the hot-blast pressure of output is bigger, therefore absolute partial pressure of oxygen can remain on big level, has satisfied the needs of general boiler.To the use occasion that needs strengthen partial pressure of oxygen especially, can replenish at the exhaust port place and inject oxygen.
The form of gas turbine engine of the present invention, under with the energy power condition, volume can design very for a short time, thereby very big power-weight ratio ratio is arranged.And the fan blade rotating speed is higher, makes to adapt to less installation conditions by compact structure.
The present invention is equipped with temperature and pressure measurement cell (7) at relief opening, be used for measuring the temperature and pressure value of its output hot blast and send into controller (6) so that running parameter of the present invention is controlled, thereby reach automatic adjusting to keep the stable purpose of Operational Limits.When work, controller (6) compares the setting value of measured temperature and force value and requirement, when delivery temperature is lower than required value and exhaust pressure and also is lower than setting value, controller (6) control increases fuel flow rate, and be lower than required value but exhaust pressure when being higher than setting value when delivery temperature, controller (6) is adjusted for the angle of adjustable stator blade, to reduce the air inflow of fan blade (2), otherwise, if delivery temperature of the present invention is higher than required value and exhaust pressure when also being higher than setting value, controller (6) control reducing fuel flow rate, and be higher than required value but exhaust pressure when being lower than setting value when delivery temperature, the angle that controller (6) is punished adjustable stator leaf is adjusted, and increases the air inflow of fan blade (2).Stator blade (4) preceding what can be adjustable, they can be that the first order or first, second level or first three grade are adjustable.The present invention controls its output power by regulating the fuel flow rate of importing, and it has very wide operating range.
The present invention has used fan blade, gas generator and turbine three's combining form, constitutes a not electrification dynamic power machine that just can turn round voluntarily, and the output of high temperature mass flow air is arranged, and has played the effect of general industry boiler with air heater.Because it is big that this three's combining form has per unit volume (or weight) power, adjusts easy to use.Can under very big working conditions change scope, work.And the overall efficiency height, all energy of fuel have substantially all converted the energy of institute's exhaust body to.
The present invention can use existing gas turbine to reequip, and can also use retired aero-turbine because used in the present invention be the high temperature mass flow air that above-mentioned motor is discharged.In order to reduce repacking amount and recondition expense, also in order to solve the few electric problem of short of electricity and a part of high quality energy to be provided, can be before fan blade (2) axle termination one generator.Because these motors and turbine blade design to such an extent that can absorb bigger energy, but some air horsepower output, and the present invention who does not have a generator forms in use, can not absorb this part energy, at this moment the duty point of turbine and intrinsic optimum Working point gap are bigger.Unfavorable to use of the present invention.Therefore, can do the form of load with driving a generator.This can reach on the one hand and not change the available engine structure of being utilized, and can obtain the purpose of a part of high-quality energy (electric energy) output on the other hand.But when utilizing original gas turbine or retired aero-turbine, be at relief opening reload temperature and pressure measurement cell (7), because main output parameter at this moment becomes the two.Control target delivery temperature of the present invention and pressure, and generating etc. become secondary objective.
Control section of the present invention can adopt the measurement and control unit of electromechanical integration, structure as shown in Figure 2, it is changed to the measurement and control unit of electromechanical integration to temperature and pressure measurement cell (6) and controller (7), and it is by the central control computer (8) that can share with miscellaneous equipment, the standard industrial control that links by standard serial communication interface and central control computer (8) (being called for short RTU) (9), be loaded on the temperature-sensing element (device) (11) and the pressure-sensing device (10) of exhaust oral area, insert in RTU(9) in and two of linking with temperature-sensing element (device) (11) and pressure-sensing device (10) respectively measure adaptation module (12) and insert in RTU(9) in and control adapter module (13) composition that links to each other respectively with motor fuel flow control unit and adjustable stator blade angle adjusting.The control of the collection of its service data and comparison operation, air output and fuel flow rate is all passed through central control computer (8) and is carried out.When computer need carry out data capture or Control Parameter adjusted, earlier by the standard serial communication interface to RTU(9) send address gating signal, measurement that gating is required or control adapter module, computer reads or sends parameter then.Use the controlling method of electromechanical integration to make the control strategy and function to realize on the one hand with software, adjustment and conversion all are easy to, can expand easily on the other hand, only with installing and measuring sensing element, and at RTU(9) in insert corresponding adaptation module, just can increase measurement parameter.Control only just can increase Control Node with increasing corresponding executive component and adaptation module too.Adopt the form maintenance also easy to use of electromechanical integration, all RTU(9), various adaptation module and various sensing element and executive component all be standardized commodity, can carry out on-the-spot integral replacing easily.
