近年新建生物质电厂较多,生物质上料系统大多数采用的是皮带机加炉前螺旋给料机的形式,但普遍存在上料系统在上秸秆料时系统出现卡塞和料仓搭桥等现象,造成锅炉运行不稳定,运行效率下降。文中结合宝应协鑫生物质发电有限公司秸秆直燃锅炉上料及炉前给料系统改造,对生物质上料存在的问题及改造方案进行分析。 In recent years, there are many new biomass power plants. Most of the biomass feeding systems are in the form of a belt conveyor plus a front screw feeder. However, there are common problems such as jamming and silo bypass when the feeding system is on the straw Phenomenon, resulting in unstable boiler operation, operating efficiency decline. In this paper, Baoyin GCL Biomass Power Co., Ltd. Straw feedstock and furnace feed system transformation, the existing problems of biomass feeding and transformation programs were analyzed.
