A new, efficient clean coal combustion method, pulverized-coal fluidized bed combustion (PC-FBC) is proposed firstly in this paper. Research has been conducted on the combustion characteristics of PC-FBC on an experimental rig with 0.3 MW heat input. PC-FBC uses pulverized-coal as its fuel and integrates the characters of the pulverized coal boiler and the fluidized bed boiler. In 850 to 880 C fluidized-bed combustion zone (FBCZ) of PC-FBC, the pulverized coal can be ignited stably and releases 57.7 to 84.2% volatile substance. Seventy (70%) of the released volatile and a part of carbon are burnt in FBCZ. The highest and average gas temperatures are 1100 C and 950 to 1000 C respectively in PC-FBC. A combustion efficiency of 98 to 99% can be reached.
