Abstract
The utility model relates to a burning furnace for heat supply, which belongs to a reverse burning furnace. The utility model uses the waste, such as sawdust, broken wood dust, crop stalks, garbage, etc., as fuel. The burning furnace is composed of a charging barrel, a burning chamber, a chimney, a grate and an ash-clearing mouth, wherein, the charging barrel which is also used as a vapor chamber is positioned at the upper part of the burning chamber, and the burning chamber is also used as a heat exchanger is an interlayer tube structure. One end of the burning chamber is provided with a blower for blowing wind into the interlayer and the tube supplied by the wind, the other end of the burning chamber is a hot blast outlet, and the burning flue gas is exhausted from the chimney. When the utility model is used, the fuel is gasified, and the fuel gas is burnt, and the heat exchange is realized and controlled simultaneously. Thus, the heat exchange efficiency can be enhanced largely, the burning is complete and thorough, and the secondary pollution of tar can be avoided. Simultaneously, the hot wind and the flue gas are isolated completely; so the open fire hidden danger does not exist, and the safety use can be ensured reliably.
Description
The utility model relates to a kind of agricultural residue that uses, and as the reverse combustion heat supplying stove of sawdust, wood shavings, straw, corncob, cotton straw and rubbish the like waste, belongs to combustion heating equipment.
Utilize the burning of industry or agricultural wastes to produce existing use of stove and accessory of heat energy heat supply, relatively be typically the gasification, and combustion heating stove, its basic principle is that fuel gasification is sent into fuel gas burner combustion again through the heat exchanger heat supply, and the shortcoming of this device is that heat exchange efficiency is low, cost is high, volume is big, the tar material of incomplete combustion causes secondary pollution.Simultaneously, this equipment is owing to directly use combustion product gases as the heat energy heat supply, exists again to use dangerously, and inflammable, explosive etc. can be inscribed, and when drying material, all is restricted for the use of grain, timber, food service industry.
Inventor of the present utility model once disclosed 87202635 patent applications " downdraft gasification combustion furnace " in 1987.For the gasification that solves the heating gasification furnace and combustion process in conjunction with problem, adopt the double vaporizer of doing of hopper, intercalated water sleeve combines the method for composition heat exchanger natural wind oxygen supply with the combustion chamber, burner is simplified greatly.
The purpose of this utility model is to disclose a kind of the heat exchange efficiency low and safe in utilization problem of reverse combustion furnace to solve the aforementioned hot wind furnace of supplying hot blast.
The purpose of this utility model is to realize like this, reverse combustion heat supplying stove is made up of combustion chamber, barrel, chimney, fire grate, cleaning door, the double combustion chamber of making heat exchanger of top a. that the double barrel of doing vaporizer is positioned at the combustion chamber is the interlayer furnace wall, multilayer tubulation structure; B. combustion chamber one end has blower fan 15 air-supply in interlayer 5,6 and in the tubulation 4, and the other end is a hot-blast outlet, and combustion product gases is discharged from chimney.C. the fixedly air supplying ring 7 of uniform fresh air inlet is established in interlayer furnace wall in combustion chamber, barrel bottom corresponding positions installs the movable air supplying ring 8 of uniform fresh air inlet, the fresh air inlet position is corresponding in the middle of the interlayer furnace wall, combustion chamber, and the air communication of the interlayer of flowing through is crossed fresh air inlet and provided oxygen to the combustion chamber.Jacket wall is obliquely installed deflector in the combustion chamber, and one or more cleaning doors are established in the bottom, combustion chamber, and chimney is set up defences and ended the anti-overflow ring that tar overflows.
Adopt reverse combustion furnace technique for displaying progress effect following points of the present utility model:
1. hot blast and flue gas are isolated, for clean hot air, and the normal pressure operation, safe in utilization, the scope of application is extensive.
2. the air-flow that blows into fresh air inlet in the interlayer forms circulation in the combustion chamber, greatly improves efficiency of combustion, and there is not secondary pollution in burning fully.
3. by rotation activity air supplying ring, can control the fuel chambers combustion position, thereby control air outlet temperature is simple, convenient.
4. simple in structure, it is low to manufacture cost.
The utility model can use sawdust, wood fragments bits, crops straw skewer, rubbish the like waste to be fuel, is used for the drying, heating etc. of industry, agricultural.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of reverse combustion heat supplying stove.
Among the figure 1. chimneys, 2. anti-overflow rings (preventing that tar from overflowing) 3. lead cigarette awl tube 4. heat-transfer pipes (many of multilayers) 5. in cover (burner hearth) 6. overcoat (furnace wall) 7. fixedly air supplying ring 8. movable air supplying ring 9. barrels 10. sealing rings 11. barrels cover 12. cleaning doors, 13. deflectors, 14. combustion chambers, 15. axial flow blowers, 16. fire grates, 17. fresh air inlets.
Adopt reverse combustion heat supplying stove of the present utility model, fill it up with fuel after the igniting in barrel, start blower fan, regulate air supplying ring with control air outlet temperature, fuel falls automatically with combustion process in the barrel, and the thermal efficiency reaches 60-80%.
