摘要

通过试验确认低负荷时引风机出口烟气能克服脱硫系统的沿程阻力

当锅炉总风量低于1700t/h以下时

脱硫系统停运增压风机

保持动叶全开

引风机适当增加出力

可满足锅炉和脱硫系统安全稳定运行

显著降低了厂用电耗.取得了良好的经济效果。为防止其对锅炉运行产生影响

在设计控制逻辑时采取了相应的预防措施。

对炉膛负压波动大、引风机失速、烟气泄漏等方面的问题进行了分析

提出了解决问题的可行性方案

能够保证锅炉的稳定运行。

Abstract

The results of experiment confirmed that the flue gas in induced draft fan outlet can overcome the on-way resistance of FGD under low load.When the total air volume of boiler is less than 1 700 t/h

the boiler and the FGD could be operated safely and stably and the auxiliary power consumptions had been reduced notably by stopping booster fan

keeping the moving vane wide-open and increasing the output of induced draft fan

and economic effect was satisfactory.In order to prevent these methods to influence boiler operation

corresponding measures were adopted during control logic design.The negative pressure of furnace fluctuating greatly

induced draft fan stalling and the flue gas leaking were analyzed

and the feasible options to solve the problems were presented.
