Abstract: The burning characteristics of the biomass gas and the structure of the BCT-1 burner were given in the paper. The BCT-1 burner adopts blast and diffuse combustion pattern. In the design, diesel oil is used to ignite the gas in order to ensure that the burner can be ignited successfully, for the gas has a high ignition point. The burner was equipped with an automatic control unit for long and safe operation. The burner performances meet the standard of gas burner: its burning efficiency is 98% and CO in smoke is less than 1×10^-6.
