The invention discloses an oxygen-enriched combustion method of a biomass furnace, belonging to the field of a combustion method of the biomass furnace. The oxygen-enriched combustion method of the biomass furnace comprises the steps that air enters a hearth from air feeding channels of a main furnace; the air feeding channels of the main furnace are arranged at the top of the hearth and are uniformly arranged at the periphery of an exhaust channel; biomass fuel is burned from top to bottom; the combustion exhaust gas is discharged from the exhaust channel; in the combustion process, the air pressure of an outlet of the exhaust channel is less than the air pressure of an inlet of the exhaust channel and the air pressure in the hearth is less than the air pressure at the air feeding channels of the main furnace, so as to form suck-back oxygen supply. The biomass furnace provided by the invention overcomes the traditional combustion method, breaks through the constraint of traditional biomass furnace concept, a
