Rotary flame type smokeless firewood gasification furnace

Abstract

The invention discloses a rotary flame type smokeless firewood gasification furnace which comprises a combustion barrel arranged above a gasification chamber, a wind wheel plate capable of generating rotary airflow is arranged on the bottom face of the combustion barrel, and the lower portion of the wind wheel plate is communicated with a bottom air inlet duct; an opening in the lower end of the combustion barrel is communicated with the gasification chamber and is provided with an inner guide plate capable of generating rotating airflow; the gasification chamber is communicated with a lower air inlet duct arranged at the bottom and a side air inlet duct arranged on the side edge; the gasification chamber is connected with a fuel bin; the lower air inlet duct is communicated with the fuel bin through an upper air outlet formed in the upper portion; the side air inlet duct is communicated with the fuel bin through a side air outlet formed in the side edge; the combustion barrel is sleeved with an outer sleeve; vent holes are distributed in the side wall of the combustion barrel; and an opening in the lower end of the outer barrel is communicated with the outside and is provided with an outer guide plate capable of generating rotary airflow. According to the rotary flame type smokeless firewood gasification furnace, smokeless combustion can be achieved only by adopting common firewood as fuel without external active oxygen supply, the size is small, generated flames are large, and the gasification furnace is very suitable for being used in rural families.

Description

technical field [0001] The invention relates to the technical field of biomass energy utilization, in particular to a rotary flame smokeless firewood gasifier capable of realizing smokeless combustion after wood fuel is gasified without adding external power. Background technique [0002] When wood burns naturally in the air, it will produce very large smoke due to insufficient oxygen supply. The charcoal firing process is the most typical case. However, ordinary wood-fired stoves have at most two air intakes, which still produce relatively large flue gas. Usually, the combustion environment is improved by designing a chimney, but this pollutes the environment and wastes energy. The main components of flue gas are carbon particles and carbon monoxide. If the oxygen supply is sufficient, it can be completely burned into carbon dioxide to achieve the purpose of environmental protection and energy saving. [0003] At present, even wood-fired stoves or wood-fired stoves that us...

Problems solved by technology

[0003] At present, even wood-fired stoves or wood-fired stoves that use new biomass pellet fuels cannot achieve smokeless combustion without additional energy drive to add an external blower mechanism to actively supplement sufficient oxygen.
