Novel biomass gasification combustion furnace for door

Abstract

The invention discloses a novel household biomass gasification combustion furnace which belongs to the field of biomass energy utilization. The novel household biomass gasification combustion furnace comprises an ash discharge outlet, an ash discharge control device, an outer casing of a furnace body, an inner casing of the furnace body, an air register, a furnace cover and a bottom ash bin. The combustion furnace is applicable to a variety of biomass fuels and can be widely applied in regions which are rich in biomass resources. Furthermore, the gasification and the combustion of biomass achieve the integration, the problem of tar formation is solved during the process, and flue gas after the combustion does not contain the tar, thereby not needing the treatment of the tar; a filter mesh is added in the furnace, thereby well filtering fly ash and greatly reducing the emissions of smoke, dust and other solid small particles. The high-efficient gasification combustion of the biomass and the high-efficient clean utilization are achieved through the adjustment. Therefore, the invention has the characteristics of high efficiency, low cost, simple and safe operation, etc.

Description

technical field [0001] The invention belongs to a biomass energy utilization device, in particular to a novel household biomass gasification combustion furnace. Background technique [0002] my country is rich in biomass resources, with an annual output of more than 700 million tons of crop straw, and more than 300 million tons of forest biomass can be used as energy. At present, rural areas still use burning straw or forest biomass for cooking or heating. Usually, the straw or forest biomass is burned directly, which produces a lot of smoke and dust, which affects the surrounding environmental sanitation and causes environmental pollution. Although, recently there are gasifiers that convert straw into gas, the application of small-scale household biomass gasifiers in daily life is close to maturity. For example, Chinese patent ZL 200420041690.7 discloses a household small-scale straw gasifier; Chinese patent No. ZL 200320106112.2 discloses a straw firewood gasifier; Chines...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a gasifier suitable for agricultural and forestry wastes in view of the relatively high manufacturing and processing costs of the gasifier in the prior art and the production of a large amount of smoke and dust during use, which affects the surrounding environmental sanitation, causes environmental pollution, and tar treatment.
