Description

Faggot tangerine bar vapourizing furnace

Technical field

The utility model relates to the stove and accessory technical field, and especially a kind of is the stove and accessory of fuel production inflammable gas with timber, grass or crops tangerine bar etc.

Background technology

Faggot tangerine bar vapourizing furnace is to be the fuel production inflammable gas with timber, grass or crops tangerine bar etc., it can make vast in to use the bavin standing grain to be clean fuel as the Rural areas change faggot of main fuel, improve the heat utilization efficiency of faggot, make that utilizing of heat energy is more convenient, home environment more cleans, totally.Existing faggot tangerine bar vapourizing furnace is as " multifunctional biomass vapourizing furnace " (patent announcement CN2442996Y, the day for announcing is August 15 calendar year 2001), this stove is that the burner hearth bottom at a back taper is provided with fire grate, above fire grate, be provided with the kindling material district, on the furnace lining around the kindling material district end face, be provided with a plurality of blast orifices that communicate with the even pressure of air inlet chamber, be provided with the collection chamber and the water jacket of sandwich structure on the top of body of heater, collection chamber is the cleaner of heat-eliminating medium with chimney and one with the air respectively by a threeway.This class vapourizing furnace, I am through secular use, test, find them because shape, the ratio of its internal furnace, kindling material district, air inlet even pressure chamber and collection chamber are improper, the structure of cleaner is also reasonable inadequately, therefore, can only burn as frivolous, tiny, exsiccant fuel such as hay, dry tangerine bar, wooden chaffs, for bigger timber, humidity greater than 15% fuel, then can't the production combustion gas, suitability is relatively poor, especially is difficult to the southern area that is applicable to that wetness of fuel is bigger.

Summary of the invention

The purpose of this utility model provides a kind of faggot tangerine bar vapourizing furnace, and the problem that it mainly solves is to make the adaptability of raising to wetness of fuel, secondly is can make thick timber need not split urine to can be used as the raw material production combustion gas.

In order to address the above problem, the scheme that the utility model adopts is: it includes back taper burner hearth, fire grate, Hui Cang, burner hearth blast inlet, even body of heater and the cleaner of pressing the collection chamber formation of chamber, combustion gas of air inlet, and the thermofin between the described burner hearth and the external world is the air chamber of sandwich structure; Be contained in the water tank after described cleaner is connected by double-pipe condenser and comb condenser and constitute; Described double-pipe condenser is contained in the bassoon by the tubule of a lower ending opening and constitutes, and the top of described tubule is provided with stretches out the outer inlet mouth of described bassoon, and described bassoon is provided with air outlet and leakage fluid dram; Described comb condenser is made of upper chamber and lower chamber and many prolongs being communicated with this upper chamber and lower chamber, and upper chamber is provided with inlet mouth, and lower chamber is provided with air outlet and leakage fluid dram.

Above-mentioned air chamber is for being even collection chamber and the heat insulation air chamber of pressing chamber, combustion gas of described air inlet; Above-mentioned burner hearth blast inlet generally will be higher than the height H of fire grate greater than 60 millimeters; The even volumetric ratio of chamber of pressing of the volume of described burner hearth and described air inlet is preferably 1.5～3.5: 1; The volume of described burner hearth and the volumetric ratio of described collection chamber are preferably 5～10: 1.The leakage fluid dram of above-mentioned double-pipe condenser and comb condenser can be equipped with bend pipe.

Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:

1, isolated by the air chamber of sandwich structure between the side of burner hearth and the external world, cancelled water jacket of the prior art, thereby prevented to be blended in the burner hearth water vapour too much in the combustion gas under the inboard wall of burner hearth condensate flow, influenced the burning gas making of fuel; Be contained in the water tank after cleaner is connected by double-pipe condenser and comb condenser and can improve the decontamination effect improving of combustion gas greatly, the tar in the combustion gas, water vapour are removed totally substantially.Test-results shows: but adopt 8.5 kilograms in aqueous timber, 2.75 kilograms of continuous production inflammable gass of wood shavings (gas furnace is with the per hour firepower burning of boiled 30 kg of water) to reach 5.5 hours, discharge tar and water of condensation reach 4.6 kilograms from cleaner simultaneously, can adapt to raw material humidity and reach 40.9%.In addition, the timber that is used for process gas can directly adopt diameter to reach 30 centimetres living timber, need not rive.

2, the burner hearth blast inlet is set and is higher than the height H of fire grate greater than 60 millimeters; The volumetric ratio of the even pressure of the volume of burner hearth and air inlet chamber is 1.5～3.5: 1; The volume of burner hearth and the volumetric ratio of collection chamber are 5～10: 1, can further improve the combustion conditions in the stove.The results showed, this stove in use, fill up fuel after, fiddle with for twice in the stove the fuel except that 1, but almost no longer need to regulate just ordinary production combustion gas of management.

3, the leakage fluid dram at double-pipe condenser and comb condenser is equipped with bend pipe, and the tar and the water of condensation that leach are discharged automatically, and exempting prior art needs often to open aperiodically bothering of tapping valve discharge tar and water of condensation.
