Biomass high-level cold wood burner and use method thereof

Abstract

The invention discloses a biomass high-level cold wood burner and a use method thereof; the structure includes a furnace body and a feed inlet on the furnace body; the side wall of the furnace body is equipped with a wood gas upper outlet and a wood gas lower outlet, and the bottom of the furnace body is equipped with an ash-settling chamber; the ash-settling chamber is equipped with a plate-overturning ash discharge furnace disc, and the bottom of the ash-settling chamber is equipped with a carbon discharge port; the lower part of the furnace body is equipped with an ash discharge power mechanism; the ash discharge power mechanism is connected with a hollow rotation pipe; the lower end of the rotation pipe is arranged in a wind inlet box, and the upper end of the rotation pipe is equipped with a plurality of scraping blades and is arranged in the ash-settling chamber; the plate-overturning ash discharge furnace disc is arranged at the side face of the scraping blades by connecting rods; the upper end of the rotation pipe is connected with a center oxygen inlet pipe arranged in the furnace body; the center oxygen inlet pipe is equipped with a plurality of through holes; the outside of the furnace body is vertically equipped with a plurality of outer wall oxygen inlet pipes. The use method comprises that a material is fed through the feed inlet and then is burnt in the furnace body, at the same time, oxygen is supplemented through the outer wall oxygen inlet pipes and / or the center oxygen inlet pipe, and thus wood gas is obtained from the wood gas upper outlet and the wood gas lower outlet, and ash is discharged through the plate-overturning ash discharge furnace disc.

Description

technical field [0001] The invention relates to the field of wood burners, in particular to a biomass high-rise cold wood burner and its use method. Background technique [0002] In recent years, the energy shortage has become increasingly serious, and the world is looking for new energy sources that can replace oil and coal; and wood gas is one of the alternative energy sources with great development potential. Generally, wood gas uses wood waste, forest logging residues, crop straw and other carbon-containing organic matter as raw materials, and uses air and water as gasification agents. Wood gas has a wide range of sources of raw materials, and after the wood is converted into wood gas, the combustion process is easy to mediate, complete combustion, high flame temperature, no charcoal residue, easy to transport and other advantages are more and more favored by consumers. [0003] Generally, under the action of high temperature and gasification agent (air or oxidizing sub...
