Experimental Study of Anthracite Combustion in Circulating Fluidized Bed Boilers

An introduction to the experimental work done on boilers is presented, together with an analysis of the results obtained, which show that anthracite can effectively be burnt. In circulating fluidized beds, but with existing problems of high ignition temperature, large content of carbon in the fly ash and relatively low efficiency of combustion. Based on test results and engineering experience, some suggestions are made for raising the combustion of anthracite, lowering the carbon content in the fly ash und for designing circulating fluidized bed boilers that may burn anthracite efficiently.
