摘　　要：通过对直接锅炉、再热器的布置,以及再热汽温控制的讨论,指出了影响再热汽温变化的因素,并研究了机组在启动过程中对再热汽温的控制、正常运行时再热汽温的调整、变工况运行时再热汽温的调整、机组停运阶段再热汽温的控制,以探索汽温调节方法指导实践工作.Through the discussion of the arrangement of direct boiler and reheater and the control of reheater temperature,this paper points out the factors affecting the change of reheat steam temperature,and it studies the control of reheat steam temperature during the start up process of the unit,the adjustment of the reheating steam temperature in normal operation,the reheating steam temperature adjustment during the variable operating condition and the control of the reheating steam temperature during the shutdown phase of the unit so as to explore the steam temperature regulation method to guide the practice.

关 键 词：再热汽温 超前调节 安全经济
