Modification of Tail Gas Blending System in Recirculating Fluidized Bed Boiler
Chemical tail gas has the characteristics of complex composition,high pollution,strong flammability and explosiveness.Direct discharge can lead to environmental pollution and waste of recyclable resources.With the promotion and application of circulating fluidized bed boilers,chemical tail gas can be mixed and burned in recirculating fluidized bed boilers.Firstly,an overview of YJ-240/9.8-M recirculating fluidized bed boiler was provided;then,based on the key points of the blending modification process,tail gas data from the blending modification,theoretical performance testing,pipeline layout,etc.,a blending system modification scheme was formulated;finally,simulation experiments were conducted to improve the tail gas blending system,and through practical application,it was proven that the blending system can effectively utilize chemical tail gas,achieve the recovery of heat value from synthetic tail gas and chemical tail gas,and achieve standard emissions.
