摘　　要：分析再热汽温调节手段方面的问题 ,讨论了影响再热汽温的因素 ,对当前应用最多的两种调温手段 :烟气挡板和摆动燃烧器存在的问题进行了研究 ,并根据台州电厂 8号炉和北仑 3号炉的试验结果给出了两种不同型式的烟气调温挡板开度与过。With the electric power market steadily taking shape power plant owners are paying increased attention to the cost effectiveness of boiler plant operation. In this regard the guarantee of a required reheat steam temperature represents one of the major links in achieving the above cited aim. Meanwhile, there emerged a variety of problems regarding the methods used for reheat steam temperature regulation. Factors having an influence on the reheat steam temperature regulation are discussed, and the issues relating to the two most widely used methods for temperature regulation addressed. They are the regulation by flue gas dampers and swinging burners. Based on the test results obtained on boiler No.8 of Taizhou Power Plant and boiler No.3 of Beilun Plant the authors give the relationship between the opening degree of two different types of flue gas damper and the superheater and reheater side flue gas speed ratio.
