Problems solved by technology

Earth stoves use direct heating and combustion, which has low thermal efficiency, unhygienic use, and pollutes the environment
In recent years, the state has also invested a lot of money to promote the centralized gas supply system of rural straw gasification, but the key technology has not been solved, and it cannot be widely promoted, especially for mountainous and semi-mountainous areas with scattered residences and small villages and towns. , maintenance costs are too high

Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] Such as figure 1 , figure 2 As shown, the present invention includes a furnace body 8, a furnace core 3, a secondary air chamber 10, a secondary air inlet pipe 7, a fire retaining ring 11, a return flue 12, a chimney 1, and the like. There are inner and outer heat insulation layers inside the cavity of the furnace body 8, the outer heat insulation layer is filled with plant ash, and the inner heat insulation layer is filled with expanded perlite for heat preservation. Three evenly distributed secondary air intake vent pipes 7 are built between the inner and outer heat insulation layers, and the gas in the three vent pipes communicates through the cylindrical holes at the bottom of the furnace body 8 . One side of the body of furnace 8 is provided with a secondary air inlet 4 and a primary air inlet 6, the primary air inlet 6 communicates with the ash bin 5, th...

Abstract

The invention has a stove body, in the cavity of which are set three ventilating pipes. On the side of the stove body are opened secondary and primary air intakes. In the stove body there is a core, on top of which are opened three rows of staggering air vents with a 4 mm diameter each and at the bottom of which is mounted a grid. A ring secondary air chamber is disposed between the stove body and the core. In the upper part of the stove body are disposed a combustion chamber and a fire shield ring and the lower part of the stove body is a ash bunker.

Description

technical field [0001] The invention relates to solid fuel combustion equipment, in particular to a domestic direct-fired gasifier. Background technique [0002] The shortage of my country's oil and coal resources has brought about rising prices of liquefied petroleum gas and briquettes, making many farmers in mountainous and semi-mountainous areas use earthen stoves to cook firewood again. Earth stove adopts direct heating and combustion method, which has low thermal efficiency, is unhygienic to use, and pollutes the environment. In recent years, the state has also invested a lot of money to promote the centralized gas supply system of rural straw gasification, but the key technology has not been solved, and it cannot be widely promoted, especially for mountainous and semi-mountainous areas with scattered residences and small villages and towns. , The maintenance cost is too high. Contents of the invention [0003] The purpose of the present invention is to provide a ho...
