不带再循环泵超临界机组启动参数控制
|
摘要
分析某电厂不带再循环泵超临界机组锅炉在启动初期蒸汽温度偏高的原因,提出通过优化启动初期锅炉给水量、锅炉运行风量、二次风门开度、燃料量、给水温度等参数,有效解决机组冲转前期汽温偏高的问题。
Analysis the reason that causes the high steam temperature at the beginning of the unit start-up in a super-critical unit boiler without BCP in one power plant,Put forward methods of parameter optimization of boiler feed-water flow at the beginning of boiler start-up,boiler working air flow,secondary air damper value,fuel quantity and feed-water temperature and so on,It can effectively solve the problem of high steam temperature at the beginning of the turbine start-up.
