The present application relates to a kind of high-efficiency
biomass energy-saving
hot blast stove, including furnace shell, the inside one side of the furnace shell is longitudinally provided with
hearth, the inner bottom of the
hearth is horizontally provided with grate, the lower portion of the grate is communicatedly provided with ash channel, the bottom of the
hearth is close to the side of the furnace shell and is provided with feeding
assembly, the top of the hearth is laterally communicatedly provided with
flue gas passage away from the feeding
assembly, the bottom surface of the
flue gas passage is longitudinally communicatedly provided with heat exchange component, and the top surface of the
flue gas passage is provided with air extraction component;The top surface of the grate is axially provided with primary
oxygen supply mechanism;The upper middle portion of the hearth is axially suspended with secondary
oxygen supply mechanism.The primary
oxygen supply mechanism arranged in the inner bottom of the hearth can continuously supply oxygen to assist
combustion in the initial stage of
biomass fuel
combustion;The secondary
oxygen supply mechanism arranged in the upper middle portion of the hearth can supply oxygen again to assist
combustion, so that the
lighter fuel sucked up is fully combusted, and environmental
pollution is effectively reduced.
