The Analyses of Safety and Economy of Auxiliaries of Lower Load Unite

低负荷调峰运行时辅机的经济性和安全性黎立新（东南大学动力工程系，南京２１００１８）采用低负荷运行方式进行调峰的机组，其辅机的安全性和经济性，直接影响整个机组的低负荷运行能力和经济性，２００ＭＷ机组系按基本负荷设计，当该机组进行低负荷调峰运行时，有必要...

This paper analyzes the safety and economy of the main auXillaries, such as boder-feedpump,forced-draft fan , induced-draft fan and air heater, of the domestic 200MW Unite,which is de-signed for base-load , now runs at lower luad to porform the cyclic duty. The regulate methfor ofpump and fan are also analyzed and suggestion for improvement are made, some methfor of protectingthe air heater against sulfur corrcaion are introduced.
