常温纯净水通过吸收废气和冷却水套中强制冷却的热量,使水的温度升高到汽液界面温度。经过雾化器把汽液界面温度的水喷到相变室,发生相变成为蒸汽,和燃气混合换热变成过热蒸气,燃气、蒸气一起作为工质吹向透平做功。经过反复实验和计算,寻找到燃气和蒸气混合工质的最大焓值,从而冷却了燃烧室和透平叶片,减少了热伤害。采用红外线网燃烧技术破坏了有害的氮氧化合物和碳氧化合物的生成条件,保护了自然环境。采用水冷却代替气膜冷却,极大地降低了压气机的自耗功,提高了热效率和输出功率。

It is known that it is quite difficult for heat engine efficiency to increase by 1%. The efficiency of the gasoline engine is approximately 20% , diesel engine efficiency is about 30% , gas turbine efficiency is 25% and even the thermal efficiency of thermal power plant is only 40%. Where is 60% of the energy？ The problem of recycling the wasted energy has to be put into consideration. Water temperature rises to vapor-liquid interfacial temperature through the normal temperature water absorbing the heat from the exhaust gas and cooling water jacket. The water at this temperature, through atomizer, is sprayed into the phase change room causing phase change into vapor and mixes with gas interchanging into hot vapor, so gas and vapor together as working medium are blown to the turbine to work. After repeated experiments and calculation, the biggest enthalpy of mixing working medium of gas and vapor is tbund and thus cooling the combustion chamber and turbine blades and reducing the heat damage. The natural environment is protected by using infrared nets combustion technology to destroy harmful nitrogen oxides and carbon oxides generating conditions. It greatly reduces the consumption power of the compressor and improves the thermal efficiency and power output to use water cooling instead of fihn cooling.
