Abstract
The invention provides a wet-compression and regeneration cycle gas turbine, comprising wet-compression compressor, heat source, turbine, regenerator and cold source. Adding ports for water drop frog are set at the inlet of wet-compression compressor and the middle. In compressing flow of gas cycling working fluid, water drop is mixed with gas cycling working fluid and absorbs heat energy to be vaporized. The regenerator is a surface heat exchanger. Turbine exhaust enters into the high-temperature side and outlet gas of compressor enters into the low-temperature side. Under conditions of the same turbine inlet temperature, the same compressor pressure ratio and the same part efficiency, the heat efficiency of invention can be improved by about 43%-52% compared with the heat efficiency of simple cycling gas turbine and it can be improved by about 62%-75% in output power index of specific air output compared with the simple cycling gas turbine.
Description
One, technical field
What the present invention relates to is a kind of gas turbine.A kind of circulatory system of gas turbine specifically.
Two, background technique
Gas turbine can be divided into simple cycle and complex loops.Simple cycle gas turbine engine has this three major types critical piece of gas compressor, firing chamber and turbine, for improving its cycle efficiency, needs to improve turbine inlet temperature, gas compressor pressure ratio and component efficiencies.Complex-cycle gas turbine is to have increased miscellaneous part on the simple cycle basis, and the thermal procession of cycle fluid has had qualitative change, can raise the efficiency under the constant condition of loop parameters such as turbine inlet temperature, performance such as power.Simple cycle and complex-cycle gas turbine respectively have pluses and minuses, the development of since gas turbine is born, always having vied each other, and performance is improved constantly.
Three, summary of the invention
The object of the present invention is to provide a kind of wet compression-regenerative cycle combustion turbine that can further improve the efficient of gas turbine.
The object of the present invention is achieved like this: it comprises Wet Compression gas compressor, thermal source, turbine, regenerator, low-temperature receiver, be provided with the water droplet mist in the import of Wet Compression gas compressor and neutral position and add inlet, in the compression process of gas circulation working medium, water droplet mixes with gas circulation working medium and the evaporation of absorbing heat; Be provided with surface heat exchanging formula regenerator between gas compressor and turbine, high temperature side passes to turbine exhaust, and low temperature side passes to blower outlet gas.
The present invention can also comprise:
1, described thermal source is the firing chamber that directly sprays into fuel, and described low-temperature receiver is an atmosphere environment, and the cycle fluid of turbine directly enters atmosphere at last, and gas compressor sucks the fresh air of atmosphere.
2, described thermal source is a surface heat exchanging formula heating chamber, described low-temperature receiver is a surface heat exchanging formula precooler, the cycle fluid that goes out turbine enters precooler through behind the regenerator, and the gas that goes out precooler enters gas compressor, and the water of separating out that goes out precooler enters gas compressor as water droplet mist water behind water processor.
The invention belongs to complex-cycle gas turbine, although the existing complex loops unit and the technological scheme thermal efficiency than higher, technological scheme of the present invention is a complex-cycle gas turbine that efficient is higher, technology is more advanced.The present invention forms wet compression-regenerative cycle combustion turbine with simple cycle gas turbine engine and three major types critical piece technology thereof, backheat technology, wet compression technology organic integration, and effect has significantly surmounted the independent use and the existing scheme that is used in combination of original technology.
Wet compression-regenerative cycle combustion turbine of the present invention, under turbine inlet temperature, gas compressor pressure ratio and component efficiencies the same terms, comparable simple cycle gas turbine engine improves about 43%-52% aspect thermal efficiency index, improve about 62%-75% aspect the output power index of unit air mass flow; Under the equal conditions, cold/steam-recycling (S-S) is starkly lower than Wet Compression-backheat circulation at the increase rate aspect the thermal efficiency index in the complex loops of prior art---steam-recycling (STIG), a cold backheat (ICR), the water spray.
The thermodynamic cycle scheme of wet compression-regenerative cycle combustion turbine of the present invention is: from cycle fluid compression process initial point, 1) Wet Compression: main body cycle fluid (air, the helium etc.) gas compressor of flowing through boosts, simultaneously, add the water droplet mist at the flow process starting point, replenish on stream in case of necessity and add the water droplet mist, make the evaporation of water droplet longshore current journey, play cooling effect, the flow process terminal is the mixture of water vapor and main body cycle fluid; 2) regenerator low temperature side flow process: main body cycle fluid after boosting and water vapor increase temperature with high temperature side gas by surface heat exchanging in regenerator; 3) burning/heating: the heat that absorbs high temperature heat source at burning/heating chamber by direct or indirect heat transfer type; 4) acting of expanding: the acting of in turbine, expanding of High Temperature High Pressure mixed cycle working medium, decrease temperature and pressure; 5) regenerator high temperature side flow process: turbine outlet has the cycle fluid of waste heat and by surface heat exchanging heat is passed to low temperature side gas in regenerator; 6) to the low temperature cold source heat release: cycle fluid is to the low temperature cold source heat release, come back to the compression process initial point of normal temperature first pressing, for open cycle, cycle fluid is directly arranged to atmosphere, for closed cycle, indirectly to the atmosphere environment heat release, condensation simultaneously goes out the moisture that is added to cycle fluid in the Wet Compression process by precooler and refrigerant surface heat exchanging.
Theoretical foundation and principle that wet compression-regenerative cycle combustion turbine of the present invention improves the power and the thermal efficiency are: the water-drop evaporation that sprays in the gas compressor, and reduced the working medium temperature, thereby power input to compressor is reduced, the output power of unit is increased; If at this moment have only Wet Compression, do not take back heat, then the gas that compressor delivery temperature is lower directly enters the firing chamber, needs to consume the turbine inlet temperature that more fuel just can reach same high temperature, and then the fuel thermal efficiency of whole unit changes little; Compressor delivery temperature is lower than turbine-exit temperature, it is the condition that reclaims the turbine exhaust waste heat, make full use of Wet Compression blower outlet low temperature characteristics, set up regenerator, significantly reclaim exhaust heat, enter the firing chamber after the blower outlet gas temperature is raise, reduce fuel consumption, thereby output power significantly increases the significantly increase of the thermal efficiency just when accomplishing equal fuel consumption.
With similar comparison, wet compression-regenerative cycle combustion turbine performance of the present invention can access by a relatively large margin the reason that improves and be: the Wet Compression good cooling results, more approach isothermal compression, and make that power of the assembling unit increasing degree is big, backheat is deep; Be different from cooling water surface heat exchanging cooling, cooling water has been taken away a large amount of heat energy, and the water-drop evaporation of in Wet Compression, lowering the temperature to be water vapor continue to do work in the turbine of back.
