Description

Energy-saving and efficient return air furnace

Technical field

The utility model relates to a kind of energy-saving and efficient return air furnace, belongs to boiler technology field.

Background technology

At present, the stove and accessory that existing our most of family at present uses, after lighting a fire, stove and accessory environment temperature raises from lower to upper, the heat that fuel produces, and the tail gas that a part is produced by burning is discharged through exhaust outlet.Exhaust outlet is generally arranged on the top of shaft, and this heat just making fuel produce can not be utilized more fully.And in fuel combustion process, the temperature increase of shaft and boiler face is comparatively large, and the temperature increase of whole stove seat not obvious.

Utility model content

The utility model overcomes the deficiency that prior art exists, and technical problem to be solved there is provided a kind of simple and reasonable for structure, circulating-heating, the efficient return air furnace that heat utilization efficiency is high, available heat is raised the efficiency.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: energy-saving and efficient return air furnace, comprise: furnace shell and smoke pipe, body of heater is provided with in described furnace shell, burner hearth and ashes room is provided with in described body of heater, air door, described burner hearth is provided with feeding port, ashes room is provided with ashes mouth, fire grate is provided with between described burner hearth and ashes room, cavity is provided with between described furnace shell and body of heater, furnace shell top is provided with bell, and bell is higher than body of heater, the surrounding of described body of heater is provided with hot-water line, the top of described body of heater is provided with delivery port, bottom is provided with water inlet, described furnace shell is provided with smoke pipe, described smoke pipe is connected with cavity.Change smoke evacuation direction, add thermal cycle.

Preferably, the inwall of described burner hearth is provided with fire-resistant soil layer, between described fire-resistant soil layer and burner hearth, is provided with back secondary wind inleting tube, be connected with ashes room bottom described time secondary wind inleting tube.

Preferably, the inwall of described fire-resistant soil layer is provided with pipe with spiral pipe, and described pipe with spiral pipe is connected with hot-water line.

Preferably, described ashes room is provided with ash bin.

The utility model is simple and reasonable for structure, integrate cooking, heating, toast, easy to use, adopt and cavity is set between furnace shell and body of heater, and at body of heater outer setting hot-water line, burner hearth heating pipe can be made like this, the flue gas produced upwards flows and to be flowed out by smoke pipe through cavity, can carry out post bake simultaneously, and be also provided with pipe with spiral pipe in burner hearth at flue gas to hot-water line, the heat of burner hearth and fume afterheat are effectively utilized, improves heat utilization efficiency.

In addition, arrange back secondary wind inleting tube between burner hearth and fire-resistant soil layer, secondary wind inleting tube, when coal burns, carries out secondary air feed, improves burning of coal efficiency, burn vigorous, firepower is pure, the thermal efficiency is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model energy-saving and efficient return air furnace.

Fig. 2 is the internal structure schematic diagram of the utility model energy-saving and efficient return air furnace.

In figure: 1 is furnace shell, 2 is smoke pipe, and 3 is body of heater, 4 is burner hearth, and 5 is ashes room, and 6 is cavity, 7 is bell, and 8 is feeding port, and 9 is ashes mouth, 10 is fire grate, and 11 is hot-water line, and 12 is intake-outlet, 13 is water inlet, and 14 is fire-resistant soil layer, and 15 are back secondary wind inleting tube, 16 is pipe with spiral pipe, and 17 is ash bin.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment that the utility model is done is described further.

As Fig. 1, shown in Fig. 2, energy-saving and efficient return air furnace, comprise: furnace shell 1 and smoke pipe 2, body of heater 3 is provided with in described furnace shell 1, burner hearth 4 and ashes room 5 is provided with in described body of heater 3, described burner hearth 4 is provided with feeding port 8, ashes room 5 is provided with ashes mouth 9, fire grate 10 is provided with between described burner hearth 4 and ashes room 5, cavity 6 is provided with between described furnace shell 1 and body of heater 3, furnace shell 1 top is provided with bell 7, and bell 7 is higher than body of heater 3, the surrounding of body of heater 3 is provided with hot-water line 11, the top of body of heater 3 is provided with delivery port 12, bottom is provided with water inlet 13, described furnace shell 1 is provided with smoke pipe 2, described smoke pipe 2 is connected with cavity 6, the inwall of burner hearth 4 is provided with fire-resistant soil layer 14, secondary wind inleting tube 15 is provided with between described fire-resistant soil layer 14 and burner hearth 4, be connected with ashes room 5 bottom described secondary wind inleting tube 15, the inwall of fire-resistant soil layer 14 is provided with pipe with spiral pipe 16, described pipe with spiral pipe 16 is connected with hot-water line 11, ashes room 5 is provided with ash bin 17, there is air door.
