Description

Efficient combustion bavin energy-saving heating boiler

The utility model relates to a kind of boiler, relates to a kind of efficient combustion bavin energy-saving heating boiler of civilian band warming installation specifically.

Present raising along with people's living standard, also used civil boiler band warming installation in some samll cities and towns and pastoral area, rural area, often go up the civil boiler that occurs at present, the fuel used coal that all adopts basically, in pastoral area, rural area coal resource scarcity, coal price is higher, so coal-fired heating boiler is difficult to be accepted by peasants and herdsmen.And in the rural area, the pastoral area, other combustible is but very abundant, the boiler of therefore developing with non-coal fuel combustion is a blank.

The purpose of this utility model is to provide the simple in structure of pastoral area, a kind of suitable platform rural area use, thermal efficiency height, and environmental pollution is little, and volume is little, and cost is low, with the efficient combustion bavin energy-saving heating boiler of non-coal fuel combustion.

The purpose of this utility model is achieved in that

The furnace water jacket upper side of interior dress recirculated water connects the flue water jacket, be installed into water pipe in said furnace water jacket bottom, outlet pipe is installed on said flue water jacket top, said furnace water jacket top is a boiler face, in said furnace water jacket, grate is installed, the waterpipe type fire bars is installed on the body of heater above the said grate, it above the said fire bars combustion chamber, have one to burn arch in the said combustion chamber, this burns arch and comprises arch face and side arch face, the said arch face of going up is connected on the body of heater below the flue, last arch face has an arc notch away from the opposite side of flue, connect said curved side arch face below this arc notch, said curved side arch face stays one to go out quirk near the fire bars place, open a fuel inlet that can play draught effect on the body of heater on said below the arch face, open the ventilating opening that ignites on the body of heater below said grate.During use, will fire bavin and add from fuel inlet, and light from the ventilating opening that ignites, fuel is burning the arch internal combustion, with the heating of the recirculated water in the body of heater, burns arch simultaneously and also is heated.

Above a blow-off pipe is installed below the water inlet pipe of said furnace water jacket.The dirt of recirculated water can be removed from here.

Advantage of the present utility model is:

Because body of heater and flue all adopt water jacket structure, so the combustion heat in the combustion chamber can be absorbed by the recirculated water in the water jacket, makes the recirculated water quick heating, and the waste heat of the cigarette that goes out in the flue can be once more absorbs by the recirculated water in the flue water jacket, and the combustion heat is further absorbed; Burn arch owing to connect one in the body of heater, after so the heat that fuel combustion produces is burnt the arch absorption, the temperature that burns arch raises, the heat that so burns arch is the recirculated water in the heating furnace body further, and can further prevent to fire bavin and will burn the time, stove body temperature reduces, and is low when high when effectively preventing the temperature of heating installation; Adopt the connected mode that goes up arch face and side arch face owing to burn arch, thereby guaranteed the space of combustion chamber, so guaranteed the fuel storage area, also guaranteed simultaneously the smoke area, reduce the circulating resistance of cigarette, prevented that effectively the fuel combustion that produces greatly owing to the smoke evacuation resistance is slow, the phenomenon of smoke pollution indoor environment; Owing in the combustion chamber, adopted the special structure that burns arch, so the combustion bavin makes progress away by going out quirk at the pyrotechnics of combustion chamber internal combustion again, so then increased the burning time of fiery cigarette in the combustion chamber, the heat that burns arch can make the unburning material in the fiery cigarette further burn again, makes combustion bavin sufficient combustion; In sum, this boiler is strong to the adaptability of fuel, more common cattle and sheep excrement, corncob, husk, crops straw, weeds, leaf etc. all can be used as fuel combustion in the pastoral area, rural area, quick heating, and temperature retention time is long, thermal efficiency height, heat loss is little, and fuel saving also can be used for heating up water cooking in heating, simple in structure, cost is low.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the suitable figure of structure of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

As Fig. 1, shown in Figure 2, furnace water jacket 4 upper side of interior dress recirculated water connect flue water jacket 9, be installed into water pipe 13 in said furnace water jacket bottom, one blow-off pipe 14 is installed below the said water inlet pipe, outlet pipe 8 is installed on said flue water jacket top, said furnace water jacket top is a boiler face 7, grate 15 is installed in said furnace water jacket, waterpipe type fire bars 12 is installed on the body of heater above the said grate, it above the said fire bars combustion chamber 11, have one to burn arch in the said combustion chamber, this burns arch and comprises arch face 6 and side arch face 5, the said arch face of going up is connected on the body of heater below the flue, last arch face has an arc notch 16 away from the opposite side of flue, as shown in Figure 2, connect said curved side arch face below this arc notch, said curved side arch face stays one to go out quirk 3 near the grate place, open a fuel inlet 10 that can play draught effect on the body of heater on said below the arch face, opening the ventilating opening 2 that ignites on the body of heater below said grate, is cleaning door 1 below the said grate.During use, to fire bavin adds from fuel inlet, ventilating opening is lighted from igniting, fuel is burning the arch internal combustion, recirculated water in the body of heater is heated, burning arch simultaneously also is heated, the heat that so burns arch is the recirculated water in the heating furnace body further, and can further prevent to fire bavin and burn the time, stove body temperature reduces, because the space of combustion chamber is very big, so guaranteed the fuel storage area, also guaranteed the smoke area simultaneously, reduce the circulating resistance of cigarette, prevented that effectively the fuel combustion that produces greatly owing to the smoke evacuation resistance is slow, the phenomenon of smoke pollution indoor environment, the special structure that burns arch has then increased the burning time of fiery cigarette in the combustion chamber, the heat that burns arch can make the unburning material in the fiery cigarette further burn again, make this boiler of combustion bavin sufficient combustion strong to the adaptability of fuel, quick heating, temperature retention time is long, thermal efficiency height also can be used for heating up water cooking in heating.
