Abstract: In order to solve the problems in biomass briquette combustion including low efficiency, exhausting gas and smoke, slagging easily and difficulty to remove, we designed a new type of combustion machine which adopt staged combustion mode. The steam boiler heating experiments were conducted and the results showed that the output of boiler was 5 300 MJ and combustion efficiency was 99.36%. The combustion gas contained CO with 0.001 45% and the contents of SO2 and NOX were 0.01% and 0.06%, respectively. Slag could be automatically broken and slagging-off under the help of automatic slag broken & clean device.

Key words: biomass briquettes, biomass boiler, combustion, air distribution
