目前循环流化床锅炉多数燃用０ ～８ ｍｍ 的宽筛燃料，而对４ ｍｍ 以下细颗粒煤的燃烧装置研究甚少。为解决细颗粒燃料在流化床锅炉中的良好燃烧问题，作者自行设计、安装了一台旋涡流化床实验台，并在实验台上做了冷、热态的试验研究，取得了较可靠的实验数据，为设计和研究细颗粒循环流化床锅炉提供了较可靠的技术依据 At present, most circulating fluidized bed boilers use 0 to 8 mm wide screen fuel, while little research is done on combustion devices for fine coal below 4 mm. In order to solve the problem of fine combustion of fine particle fuel in a fluidized bed boiler, the author designed and installed a vortex fluidized bed test bench by himself, and made cold and hot experimental studies on the test bench and obtained more reliable Experimental data for the design and study of fine-particle circulating fluidized bed boiler to provide a more reliable technical basis
