Abstract
The utility model relates to a secondary wind combustion aid structure. Two oblong holes are arranged on the bottom of a fire grate, a secondary wind pipe is communicated with the holes, and the upper part of the wind pipe is extended to a secondary wind disk point. When the utility model is used, a stove door is opened, air under the fire grate enters a combustion chamber along the secondary wind pipe, the combustion is more sufficient, the heat consumption is reduced, and the discharge of carbon monoxide gas is reduced.
Description
The utility model relates to the combustion-supporting structure of a kind of secondary wind, belongs to the technical field of stove.
In the combustion process of coal in burner, often because the barrier effect in the interior coal seam of burner hearth makes oxygen replenishment abundant inadequately, so that flame combustion is bad in the combustion chamber, the content that is entered the carbon monoxide in the atmosphere by chimney is very high, contaminated environment, and the thermal efficiency is also very low.
The purpose of this utility model is to provide a kind of secondary wind combustion-supporting structure, it can overcome above-mentioned shortcoming, open two slots under the fire grate of combustion-supporting structure, communicate with secondary ventiduct, extend secondary wind dish again, make air enter the combustion chamber, make burning more abundant, improve its thermal efficiency along airduct.
The purpose of this utility model is achieved in that
Grate (2) top is the garden disking body, and extend to a side bottom, and fire grate (2) has 2 slots (27), and secondary air channel (34) communicates with this hole (27), and secondary air channel (34) top and secondary wind dish (8) join.Secondary wind dish (8) is a garden dish, middle part porose (28), and a breach (29) is arranged at the bottom.Secondary air channel (34) is long channel-section steel (30), and its top is connected with another channel-section steel (31), and its right side becomes an arc (32).

Now in conjunction with the accompanying drawings the structure of the combustion-supporting structure of secondary wind is described in detail:
By Fig. 1,2,3,4, shaft (14) is fixed in above the furnace bottom (1) with bolt and nut, fire grate (2) is housed in the body of heater, be that filling is with alumina silicate heat-preservation cotton (6) between burner hearth (5) and the water jacket (7), filling is with rock wool (4) between water jacket (7) and the shaft (14), water jacket (7) supports with an angle steel (3) with fire grate (2) joint, secondary wind dish (8) is contained in burner hearth (5) top, wind dish (8) top is movable burner hearth (10), heat absorbing sheet (9) is housed all around, and fire drawn cover (1) is sleeved on the movable burner hearth (10), and stove hat (12) is contained in fire drawn cover (11) top, water jacket (7) upside is connected with one and connects water pipe (13), and body of heater (14) right part is shaft sub-assembly (15).
There is a handle (16) shaft (14) side, is fixed on the eye ring seat (17), on the stove hat (12) bell (18) and stove circle (20) is housed.
Shaft (14) right lower quadrant is equipped with a fire door (21), and fire door is contained on the firedoor frame (22), and shaft (14) is affixed with screw (23) nut (24) with furnace bottom (1), and stove hat (12) is fixed in the shaft top with screw (25).
By Fig. 5,6,7, fire grate (2) top is a garden disking body, and extend to a side bottom, and the inwall bottom surface of inner chamber is domatic, and fire grate (2) has 2 slots (27).
By Fig. 8,9, secondary wind dish (8) is a garden dish, middle part porose (28), and a breach (29) is arranged at the bottom.
By Figure 10,11, secondary air channel (34) is long channel-section steel (30), and its top is connected with another channel-section steel (31), and right side camber (32).
Combustion-supporting structure mainly is that 2 slots are set under fire grate, and secondary ventiduct (34) communicates in the hole therewith, and extends upwardly to secondary wind dish (8) input combustion chamber.This ventilation duct (34) is arranged on burner hearth (5) outside, fits in water jacket (7).When heating-cooking, just open fire door (21), a large amount of air below the fire grate (2) some along secondary air channel (34) through preheating be transported to the combustion chamber, airborne oxygen combines with the sufficient carbon monoxide of unburned, make burning more abundant, both reduced energy consumption, improve the thermal efficiency again, reduced the harmful components in the discharging waste gas.
Compared with prior art, secondary air combustion aid structure has following advantages:
1. 2 slots are arranged at the fire grate bottom, communicate with the secondary air channel of burner hearth outside, The Secondary Air dish is extended in the airduct upper end, can provide large quantity of air to the combustion chamber, makes burning more Add fully, improve the thermal efficiency;
2. reduce the excretion of an oxidation;
3. free from environmental pollution;
4. minimizing hear rate.
Claims (3)
1. combustion-supporting structure of secondary wind, it is characterized in that its grate (2) top is the garden disking body, extend to a side bottom, and fire grate (2) has 2 slots (27), secondary air channel (34) communicates with this hole (27), and secondary air channel (34) top and secondary wind dish (8) join.
2. according to claim 1, described structure is characterized in that secondary wind dish (8) is a garden dish, middle part porose (28), and a breach (29) is arranged at the bottom.
3. structure according to claim 1 is characterized in that secondary air channel (34) is long channel-section steel (30), and its top is connected with another channel-section steel (31), and its right side becomes an arc (32).
