Description

Coal and firewood two purpose gas burning stove

Affiliated technical field

The invention belongs to gas furnace, particularly a kind of coal and firewood two purpose gas burning stove.

Background technology

At present, Chinese patent 01249118.1 discloses a kind of biomass gasification burning cooking stove technology, is made up of gas producer and gas-cooker, is provided with the carbonated drink separation mechanism in the stove, water vapor in the saturation water combustion gas that biomass produce is discharged, make the gas furnace aerogenesis, though this gas stove energy aerogenesis source produces owing to concentrate with tar, can not recur system gas, owing to there is not filtration unit, in steam separator, can not realize gas source purification in addition, influence the thermo-efficiency of source of the gas.

Summary of the invention

The objective of the invention is to overcome above technical deficiency, the coal and firewood two purpose gas burning stove of a kind of thermo-efficiency height, continuous aerogenesis is provided.

Task of the present invention is, a kind of coal and firewood two purpose gas burning stove, in upper of furnace body gland is installed, furnace bottom is installed in the bottom, one side is installed water filling port, opposite side is drawn escape pipe through the gland below and is connected safety valve, gas valve is to burner, upper of furnace body gland below joins with escape pipe, at connecting position the ring-type cutoff trench is installed, the skirt outer upper end of giving vent to anger connects smoke exhaust pipe respectively, under connect the air water recursive filter, body of heater outside top, the position installation vent valve that communicates with water jacket, heat water valve is installed in the side, the straight tube of inboard wall of furnace body is communicated with scatterer and communicates with the cyclic water jacket of inboard wall of burner hearth, extension tube attached communicates with well heater, opposite side is installed liquidometer, fire bars top on the truncated cone-shaped furnace bottom of bottom of furnace body is provided with fuel leak-proof device and fire bars interlocking device, the side is provided with coke-removing door, on the opposite side anchor coke-supporting rod is set, same position left side, body of heater bottom has blast inlet and blower fan joins, the right side is provided with ash door, installed in front is stretched out on the blast pipe of body of heater outside the return air baffle plate is set, and the ring-type cutoff trench that the escape pipe that connects with the gland below is connected with blow-off pipe makes current enter cutoff trench on same plane.With the smoke pipe that runs on the escape pipe, pick out down tracheae and insert the air water recursive filter, top is provided with the strainer water intaking valve, in establish water gauge, connect wash water valve down, circulating filtration, remove dirt.Through safety valve, gas valve, to burner, connect water spilage tray through tracheae.Escape pipe connects sewage draining exit, upside joint detection valve.

O in the coal and firewood two purpose gas burning stove ₂Behind all burnt, under the anoxybiotic condition of high temperature, carbon and carbonic acid gas, water generation reduction reaction generate coal gas (CO, H ₂) and methane (CH ₄) inflammable gas uses for gas-cooker burning.This utility model implementation procedure: coal and firewood two purpose gas burning stove is made up of gas producer and gas-cooker, and gas producer has a shell as cyclic water jacket, heat absorber is housed in the hearth box communicates with cyclic water jacket, makes the heat in the hearth box can be than good utilisation.Design coke-supporting rod, coke-removing door, cutoff trench, fuel leak-proof device, strainer, sewage draining exit, relief valve device in the body of heater.Owing to designed said apparatus, overcome the technical deficiency of product of the same type, can the burning of continous-stable aerogenesis.Install the carbon monoxide warning device additional, alarm equipment alarm when indoor carbon monoxide reaches finite concentration, and cut off fan power automatically, prevent that CO poisons.The present invention has following characteristics: 1, flame temperature height, and firepower is violent; 2, aerogenesis, interpolation fuel and decoking are simple to operate rapidly continuously; 3, the coal bavin mixes the stove internal combustion of packing into, improves factor of created gase; 4, this gas furnace is safe and reliable as well heater, at any time controlled temperature; 5, design carbonated drink strainer makes water vapor and dirt filter, get rid of, and guarantees continuous air feed and aerogenesis quality.

The sectional view of Fig. 3 diagrammatic sketch 2.

Among the figure, the 1-body of heater; The 2-gland; The 3-vent valve; The 4-water filling port; The 5-liquidometer; The 6-heat water valve; The 7-coke-removing door; 8-return air baffle plate; The 9-blast inlet; The 10-ash door; The 11-sealed strip; The 12-safety valve; The 13-gas valve; The 14-well heater; The 15-burner; The 16-water spilage tray; The 17-heat absorber; The 18-exhaust smoke valve; 19-detects valve; The 20-sewage draining exit; The 21-cutoff trench; The 22-annular filter; The 23-water discharge valve; The 24-coke-supporting rod; 25-fuel leak-proof device; The 26-fire bars; 27-fire bars interlocking device; The 28-blower fan; The 29-smoke exhaust pipe; 30-loam cake locking latches; The 31-escape pipe; 32-strainer water intaking valve; 33-strainer water gauge; The 34-water jacket

Embodiment

With reference to accompanying drawing 1-3, open loam cake locking latches 30, gland 2 is opened, place ignition substance at furnace bottom, put into fuel again, loam cake locking latches 30 sealed covers 2 and ash door 10, after lighting ignition substance, coke-removing door 7 closes coke-removing door 7, open simultaneously exhaust smoke valve 18 make blower fan 28 electric, through blast inlet 9 air inducing superchargings, gas furnace aerogenesis behind 7-9min.Open gas valve 13 this moment, light burner 15 and close exhaust smoke valve 18, well heater 14 is heated, the heating beginning, when the about 90-120min of aerogenesis, burning generation coking because of fuel, stir coke-supporting rod 24,, fuel is well contacted with the fire in a stove before fuel is added the coking jacking that produces top to fuel, get final product normal aerogenesis continuously, at gas generation process, follow the water vapor symbiosis, one portion water steam is filtered device 22 filterings, a part forms current at the hearth box inwall, and these current are caused escape pipe by cutoff trench 21 and discharge to strainer 22 bottoms.This stove is provided with detection valve 19 and can detects combustion gas quality in addition, regulates its state of combustion according to combustion gas quality.When need add fuel, make blower fan 28 outages, open exhaust smoke valve 18 after, open again and build after coke-removing door 7 takes out cokings, open gland 2 and install fuel and compress loam cake locking latches 30, make blower fan 28 electric, aerogenesis behind 7-9min.As want to make burner to stop aerogenesis, and make blower fan 28 outages, to open exhaust smoke valve 18 and enter the state of banking up a fire, fire-sealing time can reach 5-6h, and when continuing to use, it is electric that blower fan 28 is got, but through the 7-9min aerogenesis.

Coal and firewood two purpose gas burning stove has solved biomaterial, as straw, straw, saw foam, fuel such as wood working tankage and oxen and horses excrement, the problem that can not make full use of, solved problems such as the following coal of low combustion value≤2500 kilocalories makes full use of, reduced environmental pollution, reduced cost.
