Description
Technical field
The present invention relates to a kind of gasification furnace, particularly a kind of stalk gasifier.
Background technology
A kind of existing stalk gasifier stalk gasifier as disclosed in Chinese patent storehouse【Application number：
201010160140.7；Application publication number：CN 101831321A】, by bell, body of heater, fire grate and annular air pipe institute group
Into；Insulation material is filled between body of heater and inboard wall of furnace body；The middle and lower part of inboard wall of furnace body is machined with boss, and annular air pipe is loaded on
In boss；Fire grate is placed on boss；The air inlet pipe installed on annular air pipe is passed through outside stalk gasifier through body of heater；Stove
The top of body is equipped with gas outlet, and bottom is provided with ash disposal mouthful, and bell is covered at the top of body of heater；The lower vertical peace of annular air pipe
Air escape pipe equipped with two L-types, the circumference of the gas outlets of two air escape pipes along annular air pipe is installed in the same direction；Fire grate
Son is large bamboo or wicker basket type, and edge is machined with an upper portion thereof.
Above-mentioned gasification furnace is as follows using process：Bell is opened, the comburant (-rent)s such as straw are put into stove and lighted, are passed through
External blower fan enters bottom in body of heater, shape to air inlet pipe gas transmission, air by two air escape pipes under annular air pipe
Air-flow is circularized, the comburant (-rent) in fire grate and body of heater is supplied, and takes the combustion gas of formation to upper of furnace body, is led to
Gas outlet output is crossed, is had the advantages that simple in construction, easy to use.
But the gasification furnace has two：1st, stalk is deposited on the upside of fire grate, and the flow direction of gas is from fire grate
Downside causes gas to be contacted well with stalk, causes straw burning efficiency not good on the upside of fire grate；2nd, fire grate
Can adhere to more straw ash thereon when being used for a long time hinders the straw ash on the upside of fire grate to discharge downwards, and is deposited in fire grate
Straw ash on the upside of son can influence the burning of stalk, so as to further influence the efficiency of combustion of stalk.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of stalk gasifier, solution
Technical problem is how to improve efficiency of combustion.
The purpose of the present invention can be realized by following technical proposal：A kind of stalk gasifier, including air blower one and top
The open body of heater in portion, furnace upper cover has the bell of above-mentioned open closing, the interior fire grate being provided with large bamboo or wicker basket shape of body of heater, fire grate
