Portable biomass cooking stove

Abstract

The invention relates to a portable biomass cooking stove, which comprises a stove body, a stove chamber which is arranged in the stove body and a smoke flue which is communicated with the upper part of the stove chamber. One side of the stove chamber is communicated with a material adding port. A stove door is connected at the material adding port. The lower part of the stove chamber is a stove bridge with primary air holes which are communicated with the external atmosphere. A plurality of secondary air distribution holes are arranged on the wall of the stove chamber. By reasonably distributing primary and secondary air to enable fuel to be fully combusted, the portable biomass cooking stove has the characteristics of simplicity in operation, energy saving, high efficiency, environmental friendliness and the like; and by using the movable stove door, the scope of applicable fuel is wider. The portable biomass cooking stove has a simple structure, is small, exquisite and portable, is not required to be connected with an external smoke pipe or an external fan, and is suitable for household cooking, outdoor cooking and the like.

Description

Technical field [0001] The invention relates to a solid fuel household stove, in particular to a portable biomass cooking stove. Background technique [0002] With the development of agriculture and forestry, biomass resources will become more and more. The main problem of the current use of biomass energy is that the energy utilization rate is very low and the use is unreasonable, resulting in a huge waste of resources. The earth stove burns firewood and straw, which has low combustion efficiency and high labor intensity, which also causes damage to the environment. [0003] In recent years, biomass stoves have made great progress, and some portable biomass stoves have also appeared on the market. The upper part of the furnace body is used to set up a flue to replace the fan or smoke pipe of the traditional stove. It is compact, light, and portable. The production is simple, but it also ignores a very important issue, that is, how to effectively improve the combustion and increas...

AI Technical Summary

Problems solved by technology

When the charging port is open for combustion, the secondary air entering from the door is not controlled. Too much cold air cools the flame and lowers the furnace temperature, resulting in insufficient fuel combustion and high smoke and dust emissions; when the furnace door is closed for charging. , because there is not enough air to support the combustion, the fuel is not fully combusted and the thermal efficiency is reduced
