Abstract

The utility model relates to a multipurpose smokeless stove, comprising an upright cylinder-shaped stove body, a round barrel-shaped hearth, movable fire bars, a slag outlet, and a coal feeding door. The upper part of the hearth is provided with a fire outlet. The air inlets of a first air entering pipe and a secondary air entering pipe are angled with the outer round barrel-shaped stove wall of the utility model by an angle about 25 DEG to 45 DEG to make first entering air and secondary entering air enter an annular air chamber to rotate by a high speed. A secondary air spraying hole is angled with the inner wall of the hearth by an angle from 25 DEG to 45 DEG to make secondary entering air rotate by a high speed. The movable stove bars can rotate at any time to make slag fall into a slag chamber. When a plurality of fire mouths are needed to be used, a multifunction fire path can be connected with the fire outlet in external. When a power failure is generated, a natural air supplying and secondary air entering bell mouth can be added. The utility model has the advantages of completely smoke abatement, high heat efficiency, high coal saving rate, and long service life.

Description

A kind of smokeless burning stove of using more

The utility model belongs to a kind of and uses smokeless burning stove more, and it can be used as family's warming stove, cooking stove, machine-operated factories and miness cooking stove, drinking water boiler and industrial furnace.

The present coal stove fire grate kind of China is a lot, can be divided into from the smoke-eliminating method and the theory of combustion:

1. just burning method, quantitative coal supply of girdle such as chain furnace, reciprocal grate etc., its shortcoming is to eliminate smoke not thoroughly, floor space is big.

2. backfire is raised coal burning machine as under the drawing plate lifting, and shortcoming is to block dumbly easily, chooses ature of coal.

3. simple and easy gas burner, shortcoming are to choose ature of coal, easily slagging scorification, and accommodation is limited.

4. double-layer grate or individual layer fire grate layering air feed, these class methods are the direct current air feed, can eliminate smoke sometimes, but the air residual coefficient are too big, easily slagging scorification, easy-clear increases because the convection current of air feed direction evokes the flue gas dust-exhausting quantity, the waste coal.

In order to overcome the above-mentioned shortcoming of prior art, the purpose of this utility model provides a kind of and can thoroughly eliminate smoke, dedusting, and economize on coal use smokeless burning stove more.

Many with smokeless burning stove by vertical type cylinder shape body of heater 1, cylindrical shape burner hearth 2, movable fire bars 3, annular air compartment 4, an annular secondary air chamber 5, add coal stove door 7, cleanout door 8, cinder chamber 9, exhanst gas outlet 17, air blast 16 and constitute.Set up the external quirk 18 of using more when this stove uses as many burners, set up secondary air horn mouth 21 during by the nature air feed.

Vertical type cylinder shape body of heater 1 is by inner cylinder body 2 ' and exterior cylinder 1 ' constitute, inside and outside circle cylindrical shell upper end flushes sealing, exterior cylinder is longer than inner cylinder body, the outer cylinder body outer wall promptly is a furnace body outer wall, the inner barrel inwall surrounds spherical hearth 2, furnace depth 〉=diameter, movable fire bars 3 is equipped with in the inner cylinder body bottom, movable fire bars top is provided with cleanout door 8, upper of furnace body 2/3 place is provided with and adds coal stove door 7, adding the coal stove door lower furnace is the primary zone, inner cylinder body inwall just inboard wall of burner hearth is lined with resistant to elevated temperatures refractory material lining 14, is provided with pyrotechnics outlet 17 in upper furnace, is provided with double secondary spray wind hole 6 on add coal stove door 7, upper furnace in secondary spray wind hole is a secondary combustion chamber, be provided with interlayer in the middle of the inside and outside circle cylindrical shell, the interlayer below is provided with enclosed baffle 22, and the annular space on the enclosed baffle is annular secondary air chamber 5, the exterior cylinder bottom is provided with movable air compartment baffle plate 13, by movable air compartment baffle plate, movable fire bars 3, outer cylinder body wall 1 ', dividing plate 22 surrounds a cylindrical air compartment 4.Above dividing plate 22, be provided with secondary wind inleting tube 10, this blast pipe 10 is with and is flexible coupling 11, dividing plate 22 belows are provided with blast pipe 12 one time, the air inlet of one secondary wind inleting tube becomes 25～45 with outer cylindrical wall, rotation obtains even distributing wind with this to make a secondary wind enter in the annular air compartment at a high speed, secondary spray wind hole 6 becomes 25～45 with inboard wall of burner hearth, secondary air is rotated at a high speed forms in the burner hearth to rotate secondary wind at a high speed.Inner cylinder body 2 ' the bottom be provided with movable fire bars 3, when needing, movable fire bars is rotatable, so that scarfing cinder, guarantee one time the well-ventilated, when stove is brought into use, wind enters along the air intake direction and passes movable fire bars 3 after the cylindrical shape air compartment rotates at a high speed and enter the coal seam coal is fully burned, meanwhile secondary air also enters annular air compartment along the air intake direction, rotation at a high speed in annular air compartment, enter burner hearth from secondary spray wind hole direction then, above the burner hearth at a high speed rotation with below the flue gas and the flame that rise vertically join, laterally tangent, make it abundant mixed combustion, form the smokeless flames of strong rotary combustion, the sedimentation rapidly under the tangent effect of joining of the secondary wind combustion flame of the grit of in the flue gas that rises, carrying secretly and rotation at a high speed simultaneously, the flame dust-ladens that pyrotechnics outlet 17 is gone out reduce, thereby reach smoke abatement and dust control and economize on coal, the flame temperature height is difficult for slagging scorification, does not choose the purpose of ature of coal.

This stove can be set up external many with quirk 18 when needs use many burners, how to be connected on the crater 17 of stove with quirk 18, when power failure or short of electricity, can set up nature air feed secondary air horn mouth 21, this air intake horn mouth is connected on and is flexible coupling on 11, is provided with plate 20 on burner 19 and is used for regulating with the fire amount.

The utility model its advantage compared with the prior art is:

1. eliminate smoke thoroughly, good dedusting effect, blackness of exhaustion is below 0～0.3 grade, and dust particle concentration is at 40mg/Nm ³Below;

2. thermal efficiency height, its thermal efficiency can reach 50～70%;

3. ignition temperature can reach 600～1400 ℃;

4. the coal saving rate height economizes on coal 50～70%;

5. multipurpose, applied range;

6. be difficult for slagging scorification, slag tap conveniently;

7. do not choose ature of coal, various coals all can use;

8. long service life is easy to maintenance;

9. removable resettlement, floor space is little;

10. simple to operate, easy to use.
