摘　　要：目前国内钢铁企业的煤气余能发电工程通常采用煤气加热器或凝结水低压省煤器降低锅炉排烟温度,提高锅炉效率。从理论结合实际的角度对低压省煤器及煤气加热器两种方案进行主要的经济技术对比,并提出相应系统优化方案。gas heater and condensate low-pressure economizer are usually used in the complementary gas power generation projects of domestic steel enterprises to reduce the temperature of exhaust gas and improve boiler efficiency. Economic and technical comparison of the two programs of low-pressure economizer and gas heater is carried out combining theory with practice, and the corresponding system optimization scheme is proposed.
