More Information
Summary:The invention relates to a biomass fluidized bed boiler capable of achieving top feeding, and belongs to the technical field of new energy. Boiler hearth upper and top feeding is adopted. Some smoke is introduced out from a smoke outlet, accelerated by a fan and then injected into a boiler hearth from a smoke jet flow device. A separation baffle plate is arranged at an outlet of the boiler hearth,a secondary tuyere and a tertiary tuyere are arranged on the wall of the boiler hearth, the fluidized bed boiler is creatively designed, yellow straw does not need to be preprocessed and can directlyenter a boiler to be combusted, and the combustion efficiency is high; a boiler feeding system is simple, reliable and small in floor area, no flying dust phenomenon appears in the periphery of the feeding system, and the boiler can be stably and efficiently operated for a long time. 本发明涉及种顶部进料的生物质流化床锅炉，属于新能源技术领域。本发明采用在锅炉炉膛上部、顶部进料。从烟气出口引出部分烟气经过风机加速后从烟气射流装置喷入锅炉炉膛。在锅炉炉膛出口处布置分离折流板，在锅炉炉膛壁上还有二次风口，三次风口。通过对流化床锅炉的创新设计，黄秸秆不需要进行预处理
