This paper investigates the flow and temperature distribution inside a cyclone combustor during combustion of coal and coal blend. The combustion under study is based on the actual cyclone combustor experiment rig used to test the performance of combustion when it be different coal-biomass blend is used. Experiment investigation on 100% coal combustion was also carried out and serves as a basis for the subsequent test for co-firing of different coal or biomass blend. Validation of temperature magnitude along cyclone furnace at 100% coal combustion condition shows good agreement between the measured and CFD results. Subsequent simulation of coal and biomass blend shows very good impact as it gave less error compared to experiment � Published under licence by IOP Publishing Ltd.
