摘　　要：为进一步提高火电厂的发电效率,提出利用半导体温差发电技术将温差发电模块与电站锅炉受热面相结合的方法,并建立了锅炉受热面换热量和换热面积计算模型、锅炉受热面复合温差发电计算模型、温差发电输出功率计算模型以及经济性分析模型。结果表明:该方法的计算模型合理,复合温差发电技术作为一种新型节能技术,能够使火电厂总的发电效率提高约2.9%,具有较大的经济效益和项目投资可行性。To further improve the generating efficiency of thermal power plants,a combined method of thermoelectric module with boiler heating surfaces was proposed based on the semiconductor thermoelectric power generation technology,following which,calculation models were established for the heat transfer rate and area of boiler heating surfaces and for the combined thermoelectric module-heating surface power generation,while a power output calculation model and a techno-economic analysis model were set up for the combined system.Results show that the calculation models established are reasonable.As a new energy-saving technology,the combined power generation technology can help to improve the total power generating efficiency of a thermal power plant by about 2.9%,indicating obvious economic benefits and high investment feasibility.
