Adjustments of 300 MW coal fired unit flue gas desulfurization system operation

Abstract

Abstract:

Abstract:To lower operation cost,Yunnan Huadian Kunming Power Company Limited blended non designed coal into combustion, and allowed flue gas desulfurization (FGD) systemoperation deviated from design condition. In this case,SO2 emission cannot meet new national emission requirements.After analyzing effects of design coal type to desulfurization efficiency,the author made a serious of adjustments to FGD system based oncombusting non designed coal type.After adjustment,flue gas heat exchanger air leakage is lower than 1%,desulfurization efficiency is higher than 95%,and FGD system emission meets the new requirements under full load working condition.This also created good economy benefits to the company.
