Biomass burning device

Abstract

Disclosed is a biomass burning device. The biomass burning device comprises a furnace body with a hearth. The furnace wall of the furnace body comprises an inner wall, a heat insulation and fire isolation furnace layer and an outer wall which are sequentially arranged form inside to outside. A cold-blast air channel is formed between the heat insulation and fire isolation furnace layer and the outer wall. The cold-blast air channel communicates with a cold air supply fan arranged outside the furnace body, and also communicates with the outside through a hot air duct which is arranged on the outer wall and located at the outlet position of the cold-blast air channel. The inner wall communicates with a finned tube exchanger stretching into the hot air duct. Ventilation hole channels used for communicating with the hearth and a combustion fan arranged outside the hearth are formed in the inner wall. The biomass burning device has the beneficial effects that the structural design is reasonable and simple; due to arrangement of the combustion fan and the ventilation hole channels, biomass fuel is subjected to boiling-type burning in the hearth, and burning efficiency is greatly improved; and due to special arrangement of the cold air supply fan, the cold-blast air channel and the finned tube exchanger, heat in flue gas can be converted into hot-blast air to be reused for the industry and daily life, and meanwhile emissions of soot in the air are reduced.

Description

technical field [0001] The invention belongs to the field of biomass burning devices, and in particular relates to a biomass burning device. Background technique [0002] The burning of natural resources such as coal, oil, and natural gas not only produces a large amount of smoke and dust to pollute the air, but also emits harmful gases such as sulfur dioxide, carbon dioxide, and nitrogen oxides, polluting the environment. Biomass fuels such as wood, straw, wheat straw and other raw materials are abundant, clean and environmentally friendly, and their pollution emissions are far lower than coal and other fuels. They have high combustion efficiency and can be used instead of traditional fuels, such as fuel supply for biomass combustion devices, etc. . The existing biomass combustion device has a simple structure, low thermal efficiency, and a large amount of smoke and dust is discharged into the environment. Therefore, it is necessary to design a biomass combustion device w...
