Abstract
The utility model relates to an atmospheric vertical boiler with a spiral chimney. The utility model is composed of a boiler shell body 1, a water jacket 2, a spiral water pipe 3, an energy-saving net 4 and a boiler grill 5. The water jacket is inlaid and fixed in the periphery of the primary combustion cavity 6 and the secondary combustion cavity 7 of the boiler shell body and a smoke exhaust cavity 8. The spiral water pipe is inlaid on the center of the water jacket of the interiors of the secondary combustion cavity and the smoke exhaust cavity, and is communicated with the water jacket up and down. As the utility model is additionally provided with the spiral water pipe, the smoke gas generated by combustion forms a spiral rising smoke passage in the secondary combustion cavity and the smoke exhaust cavity, the heat quantity contained in the smoke gas is fully absorbed by the water of the water jacket and the spiral pipe, and the heat efficiency is improved.
Description
The utility model belongs to the improvement of heating boiler.
There is the temperature height of the flue gas that discharges out of the furnace in the small-sized heating boiler of now not establishing the flue gas heat absorption plant, and makes boiler have the low shortcoming of the thermal efficiency.
The purpose of this utility model is a kind of atmospheric vertical boiler with spiral flue of development, and the heat that contains in the flue gas of this boiler emission can fully be absorbed, and then its thermal efficiency is improved greatly.
The utility model is made up of furnace shell, water jacket, pipe with spiral pipe, in water jacket is inlayed admittedly around furnace shell primary combustion chamber and second-time burning chamber and smoke extraction chamber.Pipe with spiral pipe is set in the water jacket center that is in second-time burning chamber and smoke extraction chamber, and it also is connected up and down with water jacket.
The utility model is owing to set up pipe with spiral pipe, the flue gas that makes burning produce forms spiralling flue in second-time burning chamber and smoke extraction chamber increased the running length of flue gas in body of heater, and its heat that contains can fully be absorbed by the water in water jacket and pipe with spiral pipe and the vertical water pipe.Improve its thermal efficiency, can reach 75-80%.But also has advantage simple in structure, safe and reliable, easy to use.
Fig. 1 is an overall structure cutaway view of the present utility model.
Embodiment: present embodiment is made up of furnace shell 1, water jacket 2, pipe with spiral pipe 3, energy saving net 4, fire grate 5.Water jacket 2 edge solid around furnace shell 1 primary combustion chamber 6 and second-time burning chamber 7 and smoke extraction chamber 8 in, pipe with spiral pipe 3 is set in the center that is in the water jacket 2 in second-time burning chamber 7 and the smoke extraction chamber 8, it also is connected up and down with water jacket 2.Also stud with a vertical water pipe 9 in the centre of pipe with spiral pipe 3, it also is connected up and down with pipe with spiral pipe.Cover on body of heater 1 and be provided with the hot-water outlet pipe 10 who is connected with water jacket 2, the pipe 12 that is connected with flue 11 is with the normal pressure mouth 13 that is connected in the stove.Be provided with return pipe 14 and the blow-off pipe 15 that communicates with water jacket in the bottom of furnace shell.Intrinsic fire grate 5 is inlayed in bottom in furnace shell 1, have slag notch 17 on the furnace shell below fire grate 5, stud with energy saving net 4 in the furnace shell on fire grate 5, also have shoot door 19 on the furnace shell 1 below energy saving net 4, have feeding port 20 on the furnace shell 1 on fire grate 5.Have secondary air outlet 21 on the furnace shell 1 on energy saving net 4.
