【Abstract】 A 75t/h circulating fluidized bed boiler was tested under various modes of operation and, as the result of an analytical study, the pressure and temperature profiles of the furnace under various load conditions are being presented. Laws that govern the dilute phase’s solid suspension density varying with load has moreover been studied and a relevant empirical corelation deduced, which may serve as a reference for automatic control of combustion systems of circulating fluidized bed boilers.
