Description

Back-fire type normal pressure Natural Circulation domestic heating stove

The utility model belongs to the heating setting, is specifically related to a kind of domestic heating stove.

In the prior art, the domestic heating stove kind is more, its structure difference, and characteristic is different.For the urban and rural residents that do not have heating system, domestic heating stove more and more is subjected to people's popular welcome.But present most domestic heating stove heat energy utilization is insufficient, and the consumption coal is more, and environment is had certain pollution.

The purpose of this utility model provides that a kind of furnace binding is reasonable in design, and heat energy utilization is abundant, and can reduce the novel household furnace of environmental pollution.

Technical solution of the present utility model is: this domestic heating stove is made up of body of heater, burner hearth and intercalated water sleeve.Wherein intercalated water sleeve is arranged on upper of furnace body, and it comprises inner water sleeve and outer water jacket, and inner water sleeve places outer water jacket center, and the inner water sleeve upper end is communicated with outer water jacket top by vertical tube, and the inner water sleeve lower end is communicated with outer jacket sidewall by annular gap.The water jacket water inlet is positioned at outer water jacket bottom one side, and delivery port is positioned at outer water jacket top center, and flue is arranged on the body of heater middle part, and is positioned at inside and outside water jacket joint.Burner hearth is arranged on the body of heater bottom, and fire door is positioned at the burner hearth front side, and fire bars is positioned at burner hearth bottom, also is provided with ash penetration hole below fire door.

For ease of the control furnace temperature, on flue, be provided with by-pass cock, when the needs furnace temperature raises, the adjustable plate of by-pass cock to be opened, furnace temperature just can rise to optimum efficiency at short notice; Otherwise, the adjustable plate of by-pass cock to be closed or semi-closed, furnace temperature then can keep constant relatively.

During the furnace operation, flame in the burner hearth is directly pounced on the body of heater top through inner water sleeve, form once circulation, then return down from inner water sleeve top baffling, to the cavity between the inside and outside water jacket, form secondary cycle, the interior most of heat of stove this moment is absorbed and used, and the residue flue gas is discharged from the flue at body of heater middle part.

Further describe the utility model below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model front view;

Accompanying drawing 2 is the utility model side view.

With reference to accompanying drawing, intercalated water sleeve is positioned at body of heater 8 tops, is made up of outer water jacket 4 and inner water sleeve 5, and inner water sleeve 5 upper ends are communicated with outer water jacket 4 tops by vertical tube 3, and inner water sleeve 5 lower ends are communicated with outer water jacket 4 sidewalls by annular gap 14.Water inlet 11 is arranged on outer water jacket bottom one side, and delivery port 13 is arranged on outer water jacket top center.Flue 2 is arranged on the body of heater middle part, and by-pass cock 1 is housed in the flue.

Inner flue gas of the stove is through the secondary cycle reverse fire combustion, volume of smoke drops on the annular gap 14 of inside and outside water jacket joint, can not be aspirated away by chimney, be provided with cleaning door 6,10 in body of heater inside and outside water jacket joint and flue bottom one side for this reason, in order to regular removing cigarette ash, so also can avoid cigarette ash to emerge surrounding environment is polluted with flue gas.

Burner hearth 15 is positioned at the body of heater bottom, and its peripheral steel plate that adopts welds, liner furnace lining 16, and fire door 7 is positioned at upper furnace the place ahead, and fire bars 12 is positioned at burner hearth bottom, is provided with 3 ash penetration holes 9 below fire door 7, and the effect that replenishes auxiliary air can also be played in this hole.

The utility model is compared with existing domestic heating stove, has big, the fuel of heating surface area Consume less, thermal efficiency high, it is simple in structure, low cost of manufacture, service life Long, effective environmental contamination reduction are a kind of household heating stoves that is easy to promote.
