With the rapid development of industry , energy and environmental issues are increasingly of concern , the the screw expansion of waste heat recovery system as an energy-saving technology gradually attention has been paid to lay a good theoretical basis for future practical application through the study . The main use of the method of theoretical analysis and computer simulations to determine the theoretical cycle of the screw expander waste heat recovery system . Analysis includes three working fluid evaporation temperature design method of consumption of the pump , the heat exchanger of the two forms , screw expander expansion ratio cycle fluid and other factors on the impact of the dual - loop system , obtained under different conditions , the working fluid is evaporated temperature optimum design method ; reasonable form of heat exchanger ; screw expander expansion ratio cycle for high quality selected basic principles. In the calculation of the single cycle the screw expansion of waste heat recovery system , the round robin system screw expander inlet state restrictions . Techno-economic and environmental analysis for the waste heat recovery , to prove the technology to improve energy efficiency and protect the environment has obvious effect .
