Abstract
The utility model discloses an atmospheric water heating boiler using solid fuel, liquid fuel and gas fuel. The atmospheric water heating boiler is mainly composed of boiler body (2) whose boiler shell forms an air sandwich structure, a burning chamber (13), a boiler mouth (14), a heating pipe (12), a trapeziform discharge flue (8) whose right and back sides are respectively in flat tooth and saw strip shapes, an end gas heating pipe (10), a chimney (6), an end gas reflux controlling valve (7), a water inlet pipe (3), an exhaust valve pipe (4), a vapor valve pipe (9), a dust removal water inlet pipe (5), an impeller exhaust pipe (1), an electric impeller (15), etc. The utility model is characterized in that the utility model can effectively utilize end gas produced by burning, and the heat-exchange area is large. The heat utilizing rate is high, and the utility model saves energy.
Description
The utility model belongs to a kind of fluid heater that is provided with heat-generating device, particularly a kind of atmospheric hot-water boiler that uses solid, liquid, gaseous fuel.
The atmospheric hot-water boiler majority that uses is directly to adorn water in the body of heater now, bottom of furnace body is provided with the combustion chamber, and being the wall and the top of body of heater, the atmospheric hot-water boiler that has all is set as the interlayer that to adorn water, the heating pipe of several layers of equidistantly transversely being staggered down in interlayer and the body of heater is connected, and the bottom of stove and top are respectively equipped with combustion chamber and exhaust opening.More than atmospheric hot-water boiler, the former and needless to say, the fire that the latter because fire in the combustion chamber is directly to after transversely staggered several layers water pipe heats down in the body of heater, the flue gas of its generation is discharged from the exhaust opening of furnace roof at once, so this stove not only heat exchange area is little, heat effect utilization rate is not high, and can not have than utilizing the tail gas that burning produces, and has caused energy waste.
The purpose of this utility model provides a kind of increasing heat exchange area, the tail gas that can effectively utilize burning to produce, and heat is imitated the utilization rate height, and structural design is more reasonably used the energy-efficient water heater of solid, liquid, gaseous fuel.
The utility model mainly by furnace shell be air-interlayer structure body of heater 2, combustion chamber 13, with body of heater in the heating tube 12, fire door 14, the front and back that are communicated with respectively be the trapezoidal cylinder smokejack 8 of flat rack saw strip, be communicated with tail gas heating tube 10 in the body of heater 2, chimney 6, tail gas recycle control valve 7, tail gas backflow delivery pipe 1, electronic impeller 15, water inlet pipe 3, air bleeding valve pipe 4, cap relief valve pipe 9, dedusting water inlet pipe 5 etc. constitute.
Below in conjunction with accompanying drawing detailed description is made in enforcement of the present utility model.
Fig. 1 is a structural representation cutaway view of the present utility model:
Fig. 2 is that A-A of Fig. 1 of the present utility model is to cutaway view.
According to Fig. 1, shown in Figure 2, the furnace shell of body of heater 2 is made air blanketing; The top of body of heater 2 is provided with water inlet pipe 3, air bleeding valve pipe 4, dedusting water inlet pipe 5, cap relief valve pipe 9; Chimney 6 is equipped with on the top of body of heater 2, be provided with a tail gas recycle control valve 7 in the lower end of chimney 6, on the wall that is positioned at the chimney 6 above the tail gas recycle control valve 7, be provided with a tail gas backflow delivery pipe 1 that is communicated in the air blanketing of body of heater 2 bottom furnace shells, an electronic impeller 15 be housed at the following head end of tail gas backflow delivery pipe 1; The bottom of body of heater 2 is located in fire door 14 and combustion chamber 13, water interlayer sealing in combustion chamber 13 and the body of heater 2, base in the combustion chamber 13 and end face and wall face are provided with the heating tube 12 that is communicated in the body of heater 2 with uniformly-spaced arranging, and the heating tube that is communicated in body of heater 2 13 that is positioned at 13 bases, combustion chamber is held concurrently as the grate of combustion chamber 13; Be provided with 6 front and backs that are communicated to chimney 6 from the combustion chamber on combustion chamber 13 end faces in body of heater 2 and respectively be the trapezoidal cylinder smokejack 8 of flat rack saw strip, the bottom of the trapezoidal cylinder smokejack 8 of this flat rack saw strip fixes to straight shape symmetric arrays on the end face of combustion chamber 13 or circular symmetric is fixed with arranging, the every positive back side on combustion chamber 13 end faces in body of heater 2 is between the surrounding of the trapezoidal cylinder smokejack of flat rack saw strip 8 bottoms and the combustion chamber 13 wants good seal, the every positive back side is the trapezoidal smokejack 8 of flat rack saw strip and is provided with 2 flat teeth 11, and the space up and down in each flat tooth 11 respectively is provided with 3 tail gas heating tubes 10 that respectively are communicated in the body of heater 2.
When using the utility model, at first fuel is delivered to ignition in the combustion chamber 13, flame heats the water in the body of heater 2 by the end face and the wall face thereof of heating tube 12 and combustion chamber 13; The tail gas that produced of burning respectively is the trapezoidal cylinder smokejack 8 of flat rack saw strip by the positive back side and tail gas heating tubes 10 of being located in each flat tooth 11 of this flue can heat the water in the body of heater 2 again; Utilize tail gas recycle control valve 7 can make again respectively to be the tail gas of discharging in the trapezoidal cylinder smokejack of flat rack saw strip 8 and get back in the air blanketing of furnace shell of body of heater 2 from the positive back side, inwall by body of heater 2 heats once more to the water in the body of heater 2, and tail gas is drained from impeller blast pipe 1 toward chimney 6 by utilizing the back several times.Just because of be like this, so reach the purpose of this utility model.
