Description

Gasification direct-fired furnace

Technical field

The present invention relates to a kind of is the stove and accessory that fuel is converted into fuel gas with the plant combustible, specifically a kind of gasification direct-fired furnace that organic plant is gasificated into gas fuel burning.

Background technology

At present in China vast rural area, particularly northern area, peasant household's wooden offals such as tangerine bar, cattle and sheep horsehit, sawdust that generally all burn wait and cook, heat up water, burn a heatable brick bed heating, the history of existing more than one thousand years.Though have coal, liquefied gas and electricity to substitute at present, these energy shortages cost an arm and a leg, over-burden in peasant household.So also developed with the stalk is the stalk gasifier of raw material, but they still exist many weak points, mainly is that gas tar oil is many, the many often stifled stove and accessorys of carbon granules, burning time is short, a little less than the firepower, calorific value is low, and the tar that body of heater produced also need be used separator, and manufacture craft is loaded down with trivial details.Use defectives such as flammable raw material scope is little.

Summary of the invention

The objective of the invention is to avoid above-mentioned weak point of the prior art, provide a kind of and all can be used as incendiary material with tangerine bar, cattle and sheep horsehit, sawdust or coal etc., the calorific value height, firepower is strong, the gasification direct-fired furnace that gas tar oil is few.

Purpose of the present invention realizes by following measure:

A kind of gasification direct-fired furnace, mainly be by smokejack 1, gasification direct-fired furnace shell body 14, gasification direct-fired furnace inner furnace 15 is formed, it is characterized in that gasification direct-fired furnace shell body 14 is cylindrical, there is cylindrical ashes thorax 23 in cylindrical gasification direct-fired furnace shell body 14 inner bottom part central authorities, there is ashes thorax shoot door 21 cylindrical ashes thorax 23 sides, round kiln grate 22 is arranged at cylindrical ashes thorax 23 tops, below fire grate 22, air blast blast pipe 20 is arranged in the ashes thorax 23, cylindrical ashes thorax 23 and be installed with above the fire grate 22 in the middle of cylindrical, be conical gasification direct-fired furnace inner furnace 15 up and down, fixedly connected with circular gas combustion mouth 5 edges with connecting plate 10 in gasification direct-fired furnace inner furnace 15 tops, it between cylindrical gasification direct-fired furnace shell body 14 and gasification direct-fired furnace inner furnace 15 body of heater oxygen supply district 13, in cylindrical gasification direct-fired furnace shell body 14 sides body of heater oxygen supply district's oxygen supply pipe 19 is arranged, be evenly distributed with through hole 11 between gas combustion mouth and the body of heater oxygen supply district on the fixed connecting plate 10, upper furnace body adds hot water layer 6 and inner furnace and adds between the hot water layer 16 and be connected with 2 to 4 siphunculus 12, smokejack 1 is cuboid, smokejack adds hot water layer 2 and adds hot water layer 6 with upper furnace body and be connected, have 3 to 5 heating tubes 7 and smokejack to add hot water layer 2 is connected at cuboid smokejack 1 top, the hot water layer's of adding outlet pipe 3 is arranged above the smokejack 1, adding hot water layer 6 central authorities at the upper furnace body top has the circle kitchen range 4 that is heated, and adding hot water layer 6 sides at upper furnace body has fire door 9.

The present invention compared with prior art has following beneficial effect:

Gasification direct-fired furnace at first is energy-conservation, reduction of discharging, environmental protection.The body of heater courage adopts unique cone structure, and its fuel is the occurring in nature aftergrowth, as wooden offal classes such as the stalk kinds of various plants, cattle and sheep horsehit class, sawdusts etc.Unique cone combustion chamber can increase burning time, improves the thermal efficiency.Fully burning by secondary at the gas combustion mouth by oxygen supply district and upper cone junction in unique cone combustion chamber, does not produce tar behind the burning carbonate, do not arrange black smoke, reduces smoke contamination.Long service life, safety, reliable.
