Self-suction type non-coke tar stalk and coal cooking heating furnace

Abstract

The invention relates to a self-suction tar-free haulm and coal-fired cooking and heating stove pertaining to combustion devices. The cooking and heating stove comprises a stove body 1, the bottom of which is provided with an external air inlet 2, a wind suction pipe 3 which is communicated with the external air inlet 2 and extends in the stove body 1 and an upper cover 4 positioned on the open end of the upper part of the stove body 1 and sealed with the upper edge of the stove body 1; the top of the upper cover 4 is provided with an air outlet and connected with an exit pipe 5 through a tar filtering tower 6 which is installed on the air outlet of the upper cover 4; a feeding port 16 is provided at one side of the stove body. The cooking and heating stove has the advantages that: power is unnecessary, by virtue of the wind suction pipe, air is sucked in a combustion room for supporting combustion and the built-in tar filtering tower on the upper cover has good purification effect to fuel gases and the tar collected on a filter board is reclaimed to the stove body and combusted thoroughly, the structure has the filtration effect better than a filtering device outside the stove body and the problem that the tar blocks the pipes is not incurred.

Description

technical field [0001] The invention belongs to the technical field of stoves, in particular to a tar-free environmentally friendly straw and coal-to-gas stove that can convert biomass fiber materials into combustible gas through combustion. Background technique [0002] Since straw has no substantial use at present, it is generally burned extensively in rural areas, which not only pollutes the air but also causes energy waste. So straw and coal gas is the focus of the development of this heterogeneous stove. Although some straw gas-making stoves are disclosed, the common faults of these stoves are that the gas-making continuity is poor and the firepower is not strong enough to meet the requirements for use. Therefore, the main problems of the current gas-making furnaces are: impractical, immature technology, complicated manufacturing, high cost, high difficulty, secondary pollution of tar, long pipelines, short gas-making time, low firepower, and black smoke. Stoves all n...
