Abstract

The utility model relates to an efficiency reverse flame coal saving stove. A ring hollow enclosure (4) with a hole cavity (5) is arranged on the upper surface of a stove body (1). The inner wall of the ring hollow enclosure (4) is provided with a plurality of small fume exhaust holes (6), the outer wall of the ring hollow enclosure (4) is connected with a chimney (7), and the fume exhaust holes (6) and the chimney (7) are communicated with the cavity (5). Thus, the efficiency reverse flame coal saving stove is made.

Description

The back fire high-efficient coal-saving stove

The utility model relates to a kind of improved coal furnace.

Coal furnace is indispensable kitchen range in the daily life, is used to do cooking.Existing coal furnace is of a great variety, come in every shape, but its all waste energy, defective such as contaminated environment.

The purpose of this utility model provides a kind of high-efficient coal-saving stove, utilizes this high-efficient coal-saving stove to do cooking, not only speed fast, save time and fuel saving, free from environmental pollution.

Taked following technical scheme for realizing the purpose of this utility model:

Make a kind of back fire high-efficient coal-saving stove, this coal-saving stove contains body of heater, and burner hearth is arranged in the body of heater; The enclosure of upper of furnace body is the enclosure of ring-type hollow, and the inwall of ring-type hollow enclosure has the plurality of rows pore to communicate with the cavity of ring-type hollow enclosure; The outer wall of ring-type hollow enclosure has chimney also to communicate with the cavity of ring-type hollow enclosure, makes the back fire high-efficient coal-saving stove.

The utility model only is that the enclosure of ring-type hollow is made in the enclosure of upper of furnace body, the chimney of the exhaust smoke hole of ring-type hollow enclosure inwall and outer wall is linked to each other with the cavity of ring-type hollow enclosure get final product, thereby the utility model is very easy to realize.

Utilize the utility model to do cooking, owing to after flame touches cooker, be subjected to cooker to stop the backspace downwards again of its flame, promptly fire is trapped in the time lengthening that stops in the enclosure, thereby its combustible burns once more, has made full use of the energy; Waste gas enters in the cavity from the smoke exhaust holes of enclosure inwall then, drain from chimney again, and owing to back fire of the present utility model burns once more, thereby energy savings, improve the thermal efficiency, pollution abatement, protection environment.

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

The broken section structural representation of Fig. 1, an embodiment of the utility model

The broken section structural diagrams schematic diagram of the burner hearth of Fig. 2, embodiment Fig. 1, enclosure

As shown in Figure 1 and Figure 2,1 among the figure is body of heater, formed burner hearth 3 with refractory material 2 in the body of heater 1, burner hearth 3 following the same fire bars and the dreg chamber of being provided with existing stove and accessory.Body of heater 1 usefulness insulation material of the present utility model is made, refractory material 2 usefulness be refractory brick.Above the body of heater 1 a loop hollow enclosure 4, the top driving fit of the following and body of heater 1 of ring-type hollow enclosure 4.In the inside of ring-type hollow enclosure 4 ring cavity 5 is arranged; The inwall of ring-type hollow enclosure 4 offers some exhaust smoke holes 6; The outer wall of ring-type hollow enclosure 4 is equipped with chimney 7, and exhaust smoke hole 6 and chimney 7 communicate with the cavity 5 of ring-type hollow enclosure 4.The following phase synapsis shape of the top and ring-type hollow enclosure 4 of body of heater 1 is α in an angle, and angle α all can be used by 45 °～135 ° angles, and best angle is 90 °.Some exhaust smoke holes 6 size that is opened in ring-type hollow enclosure 4 inwalls is uneven, and is little and big from chimney 7 hole far away apart from the near hole of chimney 7.Cooker is placed when doing cooking on the fire, and fire falls into and touches behind the cooker back fire downwards, makes combustible gas fully burning again on burner hearth 3 tops, is entered in the cavity 5 by exhaust smoke hole 6 then, is discharged by chimney 7 again.Because flame is burning once more down instead, thereby thermal efficiency height, energy savings, sufficient combustion, free from environmental pollution.Thereby realized the purpose of this utility model.

The utility model has following advantage:

1, simple in structure, easy to manufacture, cost is low, is convenient to promote.

2, thermal efficiency height, energy savings, sufficient combustion, protection of the environment.

Claims (3)
