Abstract

The utility model discloses a semi-gasification energy-saving firewood heating furnace, which comprises a furnace body, a furnace plate and a base, wherein a furnace mouth is arranged on the furnace plate, a furnace core is arranged in the furnace body, and a secondary air duct is formed between the furnace body and the furnace core; a grate bridge is arranged at the lower part of the furnace core, an ash bin is arranged below the grate bridge, an air duct is arranged at the side of the ash bin, and an air inlet valve is arranged on the air inlet position of the air duct; an air inlet is arranged on the side wall of the furnace core, and is communicated with the secondary air duct, and the secondary air duct is communicated with the atmosphere through the bottom of the base; and a smoke vent which is communicated with the furnace mouth is arranged on the furnace plate. In the semi-gasification energy-saving firewood heating furnace, as a secondary air inlet structure is adopted, the combustion condition of combustibles in a hearth is changed, the combustible is burnt twice respectively in the furnace core, so the combustible can be completely burnt, compared with the traditional rural heating mode of burning firewood, firewood is saved by 50%, and the better energy-saving and environmental-friendly levels are realized. The semi-gasification energy-saving firewood heating furnace has a simple structure, is easy to manufacture, and has a good use effect.

Description

The energy-saving firewood warming stove partly gasifies

Technical field

The utility model relates to a kind of stove and accessory, especially a kind of energy-saving firewood warming stove that partly gasifies.

Background technology

At present, with the faggot area of fuel in rural area, China south, winter, the air return stoves that burn coal that adopt burnt the faggot heating more, and about 50 kilograms of day consumption faggots, faggot can not completing combustions, not only wasted fuel but also contaminated environment.Though the existing firewood gasification furnace listing that can use for the rural area warming in a large number on the market now because that it really can usefulness is few, and uses cumbersomely, still awaits improving and promoting.

Summary of the invention

The purpose of this utility model is: a kind of energy-saving firewood warming stove that partly gasifies is provided, and it makes fuel be able to completing combustion, can fuel saving, can play the purpose of environmental protection again, and use simple, to overcome the deficiencies in the prior art.

The utility model is achieved in that half gasification energy-saving firewood warming stove, comprises body of heater, stone or metal plate for standing a stove on as a precaution against fire, base, is provided with fire door on stone or metal plate for standing a stove on as a precaution against fire, is provided with combustion chamber in body of heater, forms secondary air duct between body of heater and the combustion chamber; Be provided with grate in the combustion chamber bottom, below grate, be provided with ash bin, be provided with the air channel, on the air inlet position in air channel, be provided with the air intake valve in the side of ash bin; And on the sidewall of combustion chamber, be provided with fresh air inlet, and fresh air inlet is communicated with secondary air duct, and secondary air duct is communicated with atmosphere by the bottom of base; On stone or metal plate for standing a stove on as a precaution against fire, be provided with the smokejack that is communicated with fire door.

Be provided with every solar or lunar halo between body of heater and combustion chamber, combustion chamber and form secondary air duct between solar or lunar halo forms air-return duct between solar or lunar halo and body of heater, and air-return duct is connected with fire door and smokejack respectively.

Owing to adopted technique scheme, compared with prior art, the utility model has adopted the structure of twice air intake, changed the burning condition of fuel in burner hearth, make fuel in combustion chamber, carry out twice combustion respectively, can make fuel completing combustion, burn the bavin heating mode than the rural area tradition and economize bavin 50%, reach the better level of energy-conserving and environment-protective.The utility model is simple in structure, makes easily, and result of use is good.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is an another kind of structural representation of the present utility model.

The specific embodiment

Embodiment 1 of the present utility model: the structure of the energy-saving firewood warming stove that partly gasifies as shown in Figure 1, during making, produce body of heater 1, stone or metal plate for standing a stove on as a precaution against fire 2 and base 8 earlier, on stone or metal plate for standing a stove on as a precaution against fire 2, produce fire door 3, stone or metal plate for standing a stove on as a precaution against fire 2 is installed to the top of body of heater 1, in body of heater 1, install combustion chamber 4, make and form secondary air duct 11 between body of heater 1 and the combustion chamber 4; In combustion chamber 4 bottoms grate 5 is installed, an ash bin 6 is set below grate 5, produce air channel 7, an air intake valve 10 is installed on the air inlet position in air channel 7 in the side of ash bin 6; And on the sidewall of combustion chamber 4, produce fresh air inlet 9, and fresh air inlet 9 is communicated with secondary air duct 11, secondary air duct 11 is communicated with atmosphere by the bottom of base 8; On stone or metal plate for standing a stove on as a precaution against fire 2, be provided with the smokejack 12 that is communicated with fire door 3.

Embodiment 2 of the present utility model: the structure of the energy-saving firewood warming stove that partly gasifies as shown in Figure 2, during making, produce body of heater 1, stone or metal plate for standing a stove on as a precaution against fire 2 and base 8 earlier, on stone or metal plate for standing a stove on as a precaution against fire 2, produce fire door 3, stone or metal plate for standing a stove on as a precaution against fire 2 is installed to the top of body of heater 1, in body of heater 1, install combustion chamber 4, grate 5 is installed in combustion chamber 4 bottoms, an ash bin 6 is set below grate 5, produces air channel 7, an air intake valve 10 is installed on the air inlet position in air channel 7 in the side of ash bin 6; Between body of heater 1 and combustion chamber 4, be provided with every solar or lunar halo 13, combustion chamber 4 and between solar or lunar halo 13, form secondary air duct 11, and on the sidewall of combustion chamber 4, produce fresh air inlet 9, and fresh air inlet 9 is communicated with secondary air duct 11, the bottom that secondary air duct 11 passes through base 8 is communicated with atmosphere; Form air-return duct 14 between solar or lunar halo 13 and body of heater 1, air-return duct 14 is connected with fire door 3 and smokejack 12 respectively.

In combustion chamber 4, add an amount of fuel in use and light, air enters in the air channel 7 by air intake valve 10, enter into body of heater 1 below by ash bin 6 then, regulate air intake valve 10, the inlet of limit air, imperfect combustion produces a large amount of carbon monoxide owing to lack oxygen to make the fuel in the combustion chamber 4; Simultaneously, air enters into secondary air duct 11 by the bottom of base 8, enters into combustion chamber 4 tops by fresh air inlet 9 again, mixes with the carbon monoxide that produces, and makes it carry out completing combustion on combustion chamber 4 tops; The tail gas that is produced is discharged by smokejack 12.Because secondary air is natural airflow, and is basicly stable, as long as utilize air intake valve 10 to regulate primary air flow, the combustible gas scale of construction that makes the fuel generation can make fuel gas completing combustion less than the secondary air amount, reaches the purpose of energy-saving and emission-reduction.

When needs increase the heating performance of body of heater 1, can increase an air-return duct 4, the flue gas that makes discharge allows the heat of flue gas be dispersed on the body of heater 1 earlier through air-return duct 14, and its effect is to make full use of tail gas heat quantity, and is irrelevant with combustibility.
