摘要: 摘要:为防止烟气结露,烟气脱硫系统密封风机出口风温不得低于100℃,电加热装置需要连续投入运行,因此耗费大量的电能。为进一步节能降耗,降低烟气脱硫系统运行成本,华电新疆发电有限公司红雁池发电厂对挡板密封风电加热器进行了改造,利用低品质的厂用蒸汽汽源代替电能,每年可节约大量的资金。

Abstract: Abstract:In order to prevent dew formation in flue gas, the air temperature in outlet of sealing air fan in FGD system must not be lower than 100℃, and the electric heater must run continuously, which consumes a lot of electric energy. In order to save energy and reduce consumption and reduce the operation cost of FGD system, the electric heater for damper sealing air was reformed in Xinjiang Huadian Hongyanchi Power Plant. The steam source of auxiliary service steam with poor quality was used to heat the sealing air, and the electric heater was replaced. A lot of fund can be saved in year due to this reformation.
