摘要

针对某电厂1号超临界600 MW机组一次风道面积偏小

易造成一次风机失速

机组满负荷运行时因一次风送风不畅使磨煤机堵煤等问题

对磨煤机一次风控制策略进行了修改、调整和优化

并取得了良好的效果

使得机组能够在各种工况下安全、稳定运行。

Abstract

Directing against the problems of smaller cross-area in primary air duct of supercritical 600 MW unit no.1 in one power plant

the said problem is easily resulting in stall of the primary air fan

and coal blockage in the coal pulverizer due to unsmooth air flow sending from the primary air fan under full-load operation of the unit

the control strategy of primary air flowing in the coal pulverizer has been revised

adjusted

and optimized

and good effectiveness being obtained

making the unit can be safe and stable in operation under different conditions.
