Thermodynamic Study on Suction Cooling Gas Turbine Cycle Combined with Absorption-Type Refrigerating Machine Using Waste Heat

探索复合动力装置的一般热力学性能,研究结果表明,与燃气轮机简单循环相比,新的复合循环能达到相当高的热效率和比功.而且,当大气温度变化时,这种型式的燃机对于减小热效率和比功的变化能得到令人满意的结果.

Generally speaking, efficiency and output power of gas turbine are comparatiuely low, and its performance change with the variation of environmental temperature is very great.In this paper, a new type cycle is proposed expecting to solue the prohlem above.With Suction cooling, the temperature ratio is enhanced, so the gas turbine performance is improved,the refrigerating machine is drived by using waste heat.The combined plant is studied thermody namicalcy, and the results indicate that the new cycle plant can achieve higher efficieucy and output power.
