Abstract

The utility model discloses a honeycomb briquet stove for triple air-controlled, in which a two-time air wind-stopping ring and a triple air-controlled system, making honeycomb briquette combust thoroughly, lengthening combustion time, enhancing fire power, improving combustion temperature and reducing the content of harmful gas in exhaust emission after combusting.

Description

Honeycomb briquet stove for triple air-controlled

The utility model relates to that a kind of secondary wind is combustion-supporting, tertiary air temperature-adjusting type honeycomb briquette stove.

The utility model develops from secondary return air formula honeycomb briquette stove.

In known secondary return air formula honeycomb briquette stove, in general secondary wind air inlet is arranged on the body of heater left and right sides, the air door adjustable size.The secondary eye of wind is in the tile upper side, directly to the honeycomb briquet stove top.Its principle is to limit intake by the size of controlling the secondary air door, thereby makes the honeycomb briquette upper end obtain to replenish air, forms second-time burning.But it is in fact also exactly so.If it is too small that secondary air register is opened, then intake is few and inoperative; It is excessive that secondary air register is opened, and then intake is big, impacts honeycomb briquette top flare and form eddy current, hindered burning and firepower.Therefore, people generally do not use secondary air register in actual the use, draw lime-ash and the dual-purpose main air intake of wind but only use.And the utility model is at above-mentioned situation, and the secondary eye of wind is arranged on around the tile upper end, and opening upwards and is provided with the back-up ring that strile-backs, and prevents that secondary wind from impacting flare, and is provided with main air intake specially, reduces intake, prevents that draft is excessive.Also be provided with fresh air inlet three times, improved the toxic emission condition at last stove case.

The purpose of this utility model is exactly in order to design a kind of secondary wind burning quality that improves, and the honeycomb briquette stove that can carry out the tertiary air temperature adjustment.

Structure of the present utility model and operation principle thereof:

The utility model is constructed as follows (with reference to accompanying drawing 1, Fig. 2, Fig. 3):

1. go up the stove case, 2. secondary intake opening, (totally four)

3. main air intake, 4. gray-drawing port,

5. descend the stove case, 6. secondary windscreen solar or lunar halo,

7. the wind loop that strile-backs, 8. combustion-supporting wind loop,

9. exhaust stack dividing plate, 10. tempering room dividing plate,

11. the tertiary air fresh air inlet, (totally four) 12. letdown tank wind loops,

13. the combustion chamber, 14. exhaust stack,

15. tempering room, 16. letdown tanks,

The groove 17. strile-back, 18. combustion-supporting grooves,

19. heat-insulation layer, 20. fire grates, (totally four)

21. the lime-ash thorax, 22. honeycomb briquettes,

23. following stove tank shell, 24. bodies of heater,

25. the exhaust stack neck, 26. discharging road junctions,

27. table, the 28. secondary eyes of wind, (totally ten six)

29. burner hearth wind groove, (totally six)

1. a wind burning.Be provided with a main air intake (3) specially in body of heater (24) bottom, adjustable primary wind intake.

2. secondary wind is combustion-supporting.Have four secondary intake openings (2) at body of heater (24) middle part, its outlet secondary eye of wind (28) is arranged on combustion chamber (13) on every side, has 16 eyes of wind altogether.At an inboard secondary windscreen solar or lunar halo (6), the combustion-supporting wind loop of arranged outside (8) placed of the secondary eye of wind.

When honeycomb briquette took fire under a wind effect, the coal temperature raise gradually, at first discharged a large amount of coal gas from coal, coal gas second-time burning under the effect of secondary wind.Owing to be provided with wind loop that strile-backs (7) and letdown tank wind loop (12), make that the coal gas in the combustion chamber (13) is able to abundant burning, and make firepower concentrate heat radiation less.After coal gas had discharged, the carbon component in the coal burnt away, and had formed high temperature for the second time.Like this, coal is the high-temperature duration lengthening in whole combustion process, and makes harmful substance reduction in the waste gas.

3. tertiary air temperature adjustment.Under the effect of secondary wind, burning of coal speeds up, and the exhaust system temperature raises, and heat energy loss strengthens, thereby the combustion-supporting effect of secondary wind is reduced.For this reason, the utility model has designed the tertiary air thermoregulating system.Be provided with four tertiary air fresh air inlets (11) at last stove case (1) side-lower.After waste gas enters tempering room (15), mix with tertiary air, discharge out of the furnace by exhaust stack (14) then, exhaust stack is a loop configuration.

The utility model has been owing to adopted new secondary wind structure and tertiary air thermoregulating system, the heat energy of honeycomb briquette is not fully exerted and utilizes, and make and be discharged to airborne EGT and reduce, and pernicious gas reduces, the fire-sealing time lengthening.

Following accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is a forward sight outside drawing of the present utility model.

Fig. 2 is a front sectional elevation of the present utility model.

Fig. 3 is a vertical view of the present utility model.

According to diagram, last stove case (1), body of heater (24), stove case (5) employing iron sheet making down.Secondary windscreen circle (6) adopts the 0.5mm steel plate to make, must not fix, can clear up secondary intake opening (2) easily like this, strile-back wind loop (7), letdown tank wind loop (12), tempering room dividing plate (10), exhaust stack dividing plate (9) all adopts the thick iron plate of 0.3～0.5mm to make, and spot welding is got on and got final product.Fire grate (20) adopts cast iron to make.The no specific (special) requirements of heat-insulation layer (19) can be adopted any insulation material.
