Biomass direct combustion furnace

Abstract

The invention discloses a biomass direct combustion furnace which comprises a furnace pipe, a furnace end, a furnace frame, a feeding device and an air supply mechanism. The biomass direct combustion furnace is characterized in that the furnace end is fixedly connected with the furnace pipe, air supply holes are formed in the furnace end, the feeding device is fixedly arranged below the furnace pipe, the feeding device is fixedly connected with the furnace frame, the feeding device comprises a feeding barrel and a lifting mechanism, the lifting mechanism is fixedly connected with the feeding barrel, a furnace grate is arranged on the upper portion of the feeding barrel, the furnace grate is hinged to the feeding barrel, and ventilation holes are formed in the furnace grate. Biomass fuel is directly combusted through the biomass direct combustion furnace, after the upper portion is ignited, the biomass fuel is combusted from top to bottom, and when the fuel in a combustion chamber formed by the furnace pipe and the furnace grate is burnt out, secondary feeding can be carried out from the lower portion of the furnace through the feeding device.

Description

Technical field [0001] The present invention relates to a combustion furnace, and more specifically, the present invention relates to a biomass direct combustion furnace using biomass such as crop straws as fuel. Background technique [0002] Stoves are a kind of kitchen tool commonly used in people’s daily life. Common traditional stoves use non-renewable energy such as natural gas and coal as fuel. Especially when coal is used as fuel, it will directly affect the living environment of human beings. Serious pollution, as these non-renewable energy sources become less and less, people are turning their attention to renewable biomass fuels. Renewable biomass such as crop stalks and wood waste are used as raw materials to make biomass fuel, which is burned with a special burning stove to replace the use of traditional energy. This is an effective way to use biomass materials. At the same time, it can largely solve the energy problem needed in human life and production, and improve...

AI Technical Summary

Problems solved by technology

The existing related biomass direct-fired furnaces not only have low combustion efficiency, but also have a large amount of flue gas during combustion, and there are great shortcomings in the problem of continuous feeding, and secondary feeding cannot be performed. If feeding, it can only be fed from the furnace After feeding, the biomass fuel will not burn well, and harmful gases such as tar will be produced, which will bring difficulties to specific households.
