Practical Research and Application of Flue Gas Treatment Upgrading of 35 t/h Fluidized Bed Coal-fired Boiler
Aiming at the flue gas treatment and upgrading of 35 t/h fluidized bed coal-fired boiler in Jianshan Iron Mine,a variety of renovation schemes were optimized and compared from the dust removal system,desulfurization system and denitration system,respectively.The original system was upgraded with the combination dust removal process of electric bag,wet desulfurization process of limestone-gypsum and dry denitration process of active ammonia.Combined with the problems existing in the actual transformation operation,the practical research is carried out.Long-term operation shows that the concentration of dust,sulfur dioxide and sulfur dioxide in the exhaust gas reaches 0.5～2,2～35,30～50 mg/m3 respectively,which meets the requirements of the latest emission standards.
