Abstract

The invention discloses a biomass particle furnace which comprises a shell, a feeding device (1), a combustion device (2), a water circulation system, a control system (3) and an operation panel; thefeeding device (1) and a box body (21) of the combustion device (2) are both in a cylinder shape and rotate perpendicular to the ground plane by taking shafts of cylinders as rotation axes; an unloading groove (12) is divided into a plurality of unloading bins (122) by unloading bin partition plates (121); the box body (21) of the combustion device (2) is divided into 3-12 combustion cavities (211) by combustion cavity side walls (2111); openings of the unloading bins (122) and the combustion cavities (211) all face outwards; and the lower side of an outlet of an unloading passage (13) of thefeeding device (1) is the uppermost position of the box body (21). The invention provides the biomass densified biofuel combustion furnace which is automatic in unloading without blocking, full in combustion, timely in cleaning cokes and dust, efficient in running and relatively long in service life.

Description

technical field [0001] The invention relates to the field of biomass furnaces, in particular to a biomass solid molding fuel combustion furnace with automatic feeding, high combustion efficiency and synchronous automatic cleaning. Background technique [0002] Biomass solid briquette fuel is a solid fuel that compresses agricultural waste such as straw, rice husk, and wood chips into a specific shape by special equipment to increase its density. It is efficient, clean, easy to ignite, and CO 2 It can replace coal and other fossil fuels in civil fields such as cooking and heating, and industrial fields such as boiler combustion and power generation. [0003] At present, the biomass burners used in the market are mainly screw-type feeding methods. The fuel in the hopper is transported to the combustion chamber through the screw. Spiraling movements, even skids and kickbacks, may occur. Simultaneously, existing wood-burning pellet stoves are usually provided with a combustion...
