ABSRTACT:power plant desulfurization systems account for about 1% of the entire power plant, while the booster fan in the operation of power plant desulfurization system accounted for about 30%, so the unit to normal operation if the booster fan outage , by increasing the fan's output to overcome the resistance within the flue gas in the absorber to ensure that more than 95% desulfurization efficiency, not only to achieve energy saving, butalso can reduce equipment maintenance labor costs
KEY WORD:desulfurization system; on Stopping ; booster fan ; Feasibility Analysis
摘 要:
脱硫系统的厂用电约占整个厂用电的1%,而增压风机在运行中占脱硫系统的厂用电的30%左右,因此机组正常运行中如能停运增压风机,靠增大引风机的出力来克服烟气在吸收塔内的阻力来保证脱硫效率在95%以上,不仅实现节能降耗,还可以实现减少设备的维护人工成本的目的。

1.前言:
神华河北国华沧东发电有限责任公司四台机组烟气脱硫系统采用高效脱除SO2的石灰石-湿法石膏工艺。烟气脱硫系统(FGD)处理烟气量为神华河北国华沧东发电有限责任公司100%的烟气量,烟气由增压风机升压后由侧面进气口进入吸收塔,并在上升区与雾状浆液逆流接触,处理后的烟气从吸收塔顶部排出至烟囱。
