600MW超临界直流炉汽温偏差分析及调整

600MW Supercritical Once-through Boiler Steam Temperature Deviation Analysis and Adjustment

我公司#3、4炉投产后,主再热汽温左右两侧出现了一定偏差,特别是在工况变化时,偏差较大,影响机组的安全和经济运行,因此有必要对主再热汽温出现偏差的原因进行分析并在运行调整中采取相应对策,减少偏差。本文介绍了超临界直流锅炉运行中出现的汽温偏差现象及在运行调整中总结的减小汽温偏差的措施。

# 3, 4, my company after the furnace put into production, the reheat steam temperature left and right sides of a certain deviation, especially in the condition changes, the deflection, affecting the safe and economic operation of the unit, so it is necessary to master the cause of the reheat steam temperature deviation is analyzed and corresponding countermeasures were taken during operation adjustment, reduce the deviation. This paper introduced the supercritical once-through boiler and steam temperature deviation phenomenon occurred in the use of summary in operation adjustment measures for decreasing the steam temperature deviation.
