A high-efficiency biomass whirlwind direct combustion stove

A high-efficiency biomass whirlwind direct combustion stove is a stove with biomass powder fuel serving as a main combustion subject, which comprises a casing, an insulating layer and a stove container. The high-efficiency biomass whirlwind direct combustion stove is characterized in that the inner space construction of a stove cavity is optimized, and the whirlwind direct combustion stove is provided with an air supply system with a secondary air supply function, thereby achieving the purpose of omnibearing three-dimensional air distribution and being easy to realize automatic control. The structure of the high-efficiency biomass whirlwind direct combustion stove is optimized so that fuels can be sufficiently combusted, and the thermal efficiency is high. The thermal efficiency of two kilograms of biomass powders is higher than that of one kilogram of standard coal, and smoke exhaust is smaller than pollutant of fired coal, thereby being a green-clean type energy source.
