In order to cut down the fossil consumption and exhaust emission of an existing oil-burning boiler by renewable biomass energy, this paper establishes a method to combust the wood powder and A-heavy oil mixture fuel, and experimentally studies the combustion temperature and exhaust emissions. The experiments are carried out in a furnace equipped with a mixture fuel burner at different wood powder mass ratios. Compared with A-heavy oil, the mixture fuel produces less net CO_2 to provide same amount of heat. The CO concentration decreases. The NO and NO_X concentrations increase. The PM+Ash and DS+Ash concentrations increase, but the SOF concentration decreases. The experimental results show that the mixture fuel improves the combustion efficiency and lowers some exhaust emission concentrations.
