摘要

为了降低机组的厂用电率

采用汽动引风机取代电动引风机及脱硫增压风机。结合机组自动控制、快速减负荷(RB)等控制要求

设计优化了背压式汽动引风机的炉膛压力、RB等控制策略

并将其应用于某超超临界660MW机组

取得了较好的控制效果。

Abstract

In order to reduce power consumption rate of the unit

the steam-driven induced draft fan(ID fan)was applied to replace the electricity driven ID fan and desulfurization booster fan.Combining with the control requirements like automatic control

rapid runback(RB)and others

the control strategies for furnace pressure of backpressure steam driven ID fan and RB were optimized.The improved control strategies were applied on an ultra supercritical 660MW unit

and good control effect was achieved.
