WAYS FOR ANALYTIC METHOD STUDY ON INLET AIR COOLING WITH RESIDUAL HEAT REFRIGERATION IN GASSTEAM COMBINED CYCLE

对燃气蒸汽联合循环(GSCC)余热制冷进气冷却系统的国内外实践及理论研究概况作了述。基于动力机械变工况特性解析理论的应用,提出 GSCC余热制冷进气冷却系统的变工况特性解析研究途径和技术思路。结合目前GSCC已有部件和补充吸收式制冷机及换热器等变工况特性的解析解可研究GSCC余热制冷进气冷却的典型解析特性。

The situation of practice and theoritical study at home and abroad for inlet air cooling system with residucal heat refrigeration in gassteam combined cycle(GSCC) have been reviewed, pointing out the necessity and importance of developing this kind of study on varying operation condition characteristic of power system. Based on application of analytic theory for varying operation condition characteristic of power machine, the study ways and technical thinking for analytic method of varying operation condition charachteristic for inlet air cooling system with residual heat refrigeration in GSCC have been put forward. combined with existing parts of GSCC, supplementing analytic solution of varying operation condition characteristic of abosorption type refrigeration machine and heat exchanger etc., the typical analytic characteristic of inlet air cooling with residual heat refrigeration can be studied. Results of study show that the study ways suggested in this paper to be feasible.
