300MW机组锅炉主汽温、再热汽温的调整

Adjustment of main steam temperature and reheat temperature of 300MW boiler

介绍了机组正常运行和锅炉启、停过程中影响主汽温、再热汽温的主要因素,重点论述了汽温过高和过低情况下可能导致的事故并分析了产生事故的原因,给出了具体的调节方法,供处理同类问题时参考。

The main factors influencing on the main steam temperature and the reheat temperature during unit normal operation and boiler start-up and shutdown process were introduced.The accidents maybe caused by excess high steam temperature or too low steam temperature were expounded emphatically;the reasons of these accidents were analyzed;and concrete adjustment method was given,providing reference for treatment of similar problems.
