The construction principle of industrial boiler with two fluidized beds operating in parallel is briefly discussed. According to the results of heat balance tests, it is evident that the thermal efficiency of the boiler, when burning low-grade solid fuels, may be increased from 53.9 to 70.7% as compared with the ordinary single fluidized bed boiler. Dynamic properties of the combustion process in fluidized bed boilers burning low grade solid fuels with broad size distribution and firing fly ash with narrow size distribution, were determined experimentally. Problems in fluidized bed boiler design and operation were examined, and reasons for the increase in thermal efficiency are presented. 3 refs.
