Abstract
The utility model relates to an energy saving boiler, which belongs to a water heating boiler. The heat efficiency of fuel can be raised, and the pollution of exhausted smoke gas to the environment is reduced. The utility model mainly has the technical feature that the outer wall of a boiler body is arranged on an outer layer of an existing boiler water tank; an air returning pipeline is arranged between the outer layer of the water tank and the outer wall of the boiler body; an outlet above the chimney in the furnace body is arranged in the air returning pipeline; one side of the bottom of the air returning pipeline is provided with a main smoke channel which is outward turned; the upper end of the main smoke channel is provided with a chimney. When the afterheat in the smoke gas passes through the air returning pipeline, the afterheat exchanges the heat with the water in the water tank. Meanwhile, the dust separation can be realized in the main smoke channel, and the dust content of the smoke gas can be reduced.
Description
The utility model belongs to hot water space heating boiler.
Extensive use at present be the hot water space heating boiler of fuel with coal, its primary structure burner hearth is below body of heater, the burner hearth top is a chimney, the centre position of body of heater is around the heating pipe who is communicated with water tank, fuel burns in burner hearth, after heating pipe's heating, flue gas is directly discharged through the chimney of top.The weak point that this boiler exists is that the thermal efficiency is lower, and a large amount of heats is discharged with flue gas during because of burning, does not fire clean flue dust and enters and caused serious air pollution in the atmosphere.
The purpose of this utility model provides a kind of power economized boiler, improves the thermal efficiency of fuel, and reduces the pollution of the flue gas of discharge to environment.
The utility model is to realize like this.A kind of power economized boiler, the bottom of body of heater is a burner hearth 9, there is inner chimney 7 the burner hearth top, be surrounded with the aqueduct 8 that communicates with water tank 2 at the middle part of body of heater, water tank 2 is located at the skin of burner hearth and chimney, the top of water tank is equipped with the outlet pipe 6 that communicates with fin, return pipe 10 is arranged at the bottom of water tank, be provided with furnace body outer wall 3 at water tank 2 skins, interlayer between water tank 2 skins and the furnace body outer wall 3 is a return air duct 5, and the top outlet of inner chimney 7 is located in the return air duct 5, and bottom one side of return air duct 5 is provided with the flue collector 12 that outwards turns out, chimney 1 is fixed on the upper end of flue collector 12, and the side of flue collector 12 is provided with dedusting mouth 13.
Compare with existing boiler, the beneficial effects of the utility model are owing to adopted return air duct formula structure, the heat of discharging in the chimney circulate in body of heater after discharge again, heat is fully used, and has improved the thermal efficiency of fuel; Simultaneously,, flue gas is separated with flue dust, gets rid of the most of flue dust in the flue gas because flue gas forms eddy current in flue collector bottom, thus the flue gas that body of heater is discharged obviously clean, reduced pollution to environment.
Fig. 1 is a structural representation of the present utility model.
Be described further below in conjunction with embodiment.
The below of burner hearth 9 is a fire bars 11, and fuel heats the aqueduct 8 of top in burner hearth 9 internal combustion.Because aqueduct 8 communicates with cylindrical water tank 2, the water Convective Heating in water after the heating and the water tank, by outlet pipe 6 output hot water, behind radiator heat-dissipation, water temperature reduces, and is back in the water tank 2 by return pipe 10.Flue gas in the burner hearth 9 circulates downwards through return air duct 5 by the top outlet of inner chimney 7.Because the waste heat supply temperature in the flue gas is higher, thereby carry out heat exchange, further the water in the heating water tank 2 with water in the water tank 2.Flue gas flows down to the flue collector mouth of boiler bottom, owing to flue gas moves along the rounded flow direction in the bottom of return air duct 5, so at flue collector 12 bottoms formation eddy current, flue gas is separated with flue dust, flue gas is discharged along chimney 1, and flue dust falls into flue collector 12 bottoms, disposes by dedusting mouth 13.The top of body of heater is provided with loam cake 4, and coal from burner hearth 9 also can start loam cake 4 and pass through inner chimney 7 to the burner hearth coal at ordinary times, and the coal of Jia Ruing is more like this, can prolong burning of coal time and temperature retention time.
