Abstract

The utility model relates to a vortex type novel burning furnace, which is composed of a furnace chamber, a primary chamber, a primary burning chamber, a secondary burning chamber, four air inlets, a heat absorber, a slag bucket, a feed door, etc., wherein primary inlet air enters the furnace chamber from a slag bucket hole, secondary inlet air and thrice inlet air enter the lower parts of the primary burning chamber and the secondary burning chamber from the feed door, and fourth inlet air enters the secondary burning chamber through a plurality of ports on the upper part, and thus, the secondary burning chamber forms vortex burning-gas flow, and burnable objects is fully decomposed and burnt. The inlet air in every time is heated, the utility model is suitable for the burning of various burnable objects, and has the advantages of nuisance free drain, long fire sealing time, no power for the inlet air, high heat-transfer efficiency of a heat absorption part and long service life.

Description

The novel combustion furnace of vortex

Affiliated technical field

The utility model relates to the novel combustion furnace of a kind of vortex, is applicable to various coals, is particularly useful for various combustibles, comprises the burning of combustiblerefuse.

Background technology

In the various combustion furnace known today, fuel is single mostly, and mostly is the non-renewable energy; Or combustible had relatively high expectations, as faggot of drying etc.; For reaching environment protecting, also to add complicated dust pelletizing system; Mostly be air intake on the structure one time, be difficult to realize abundant burning, improve efficiency of combustion, also be difficult to decompose various toxic gases simultaneously, reach nuisanceless discharging.Many combustion furnace air intakes need power.Black dirt also causes heat transfer efficiency to reduce.

Summary of the invention

The utility model provides a kind of vortex novel combustion furnace, and this combustion furnace fuel source is wide, to various combustibles, comprises combustiblerefuse from various coals, and the higher combustible of some water content is incendivity also.Sufficient combustion, the ignition temperature height, smoke-less pollution need not to carry out dust removal process.Fire-sealing time is long, and fuel consumption is little when banking up a fire.Simple in structure, can divide several major parts assembled.Can remove a large amount of waste combustible materials, reduce fuel cost.

The technical scheme in the invention for solving the technical problem is: divide the high-temperature gas that enters for four times through heating, branch primary zone, secondary combustion chamber carry out twice combustion.Combustion-gas flow at secondary combustion chamber generation vortex has only the high temperature innocuous gas of lightweight to discharge from the hole that the secondary combustion chamber spy stays, and fuel is carried out sufficient decomposition combustion, improves efficiency of combustion, has eliminated smoke pollution simultaneously.

The beneficial effects of the utility model are: available various cheap fuel replace high-priced fuel, remove a large amount of waste combustible materials simultaneously, comprise some combustiblerefuses, realize the harmless treatment of part combustiblerefuse.Improve efficiency of combustion, realize fully burning, reach nuisanceless discharging, pollution removes smoke.Heat sink is difficult for the deposition black dirt, the heat transfer efficiency height, and service life is long.Fire-sealing time is long, and fuel consumption is little when banking up a fire.Air intake does not need power.Do not need simultaneously complicated dust pelletizing system, reduce greatly and make and maintenance cost.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.This figure is the Section View of the novel combustion furnace of vortex.

1. burner hearths among the figure, 2. primary zone, 3. heat dump, 4. slag bucket, 5. secondary combustion chamber, 6. go up the air intake preheater, 7. feed door, 8. insulation furnace wall, 9. second air inlet, 10. the 3rd air inlet, 11. the 4th air inlet, 12. furnace walls, 13. slag bucket holes, 14. fire grates.

The specific embodiment

For the first time air intake is from slag bucket hole 13 air intakes, the heat of the slag that falls in the slag bucket and by the heat of radiation of burner hearth cold wind is heated up rapidly after enter burner hearth.

Second and third time air intake from feed door 7 bottoms second air inlet 9, the 3rd air inlet 10 air intakes, enters primary zone 2 and secondary combustion chamber 5 after the heating in the air channel.

The 4th air intake enters secondary combustion chamber 5 from the 4th air inlet 11 after last air intake preheater 6 heating.

The 4th time air intake branch multichannel enters secondary combustion chamber 5, makes secondary combustion chamber 5 form the combustion-gas flow of vortexs, makes that fuel gas obtains fully, decomposition combustion fully.And by physical action, have only the high temperature innocuous gas of lightweight from the hole that secondary combustion chamber 5 spies stay, to discharge, reach the purpose of nuisanceless discharging.

Slag bucket

4 and 12 peripheries, furnace wall all have insulation furnace wall 8 to prevent heat radiation.

Absorbing by heat dump 3 of heat finished, and pollution-free because of emission gases, little to heat sink pollution corrosion, so the heat transfer efficiency height, service life is long.

Because burning branch air intake is several times finished, each intake can be controlled fully, so sufficient combustion, efficient height, air intake do not need power.Fire-sealing time is long simultaneously, and fuel consumption is little when banking up a fire.

Claims

1, the novel combustion furnace of a kind of vortex, by burner hearth, primary zone, secondary combustion chamber, four air inlets, heat dump, slag bucket, feed doors, go up air intake preheater etc. and form, it is characterized in that the air intake preheater being housed on furnace roof top, an air outlet of last air intake preheater is downwards over against flame, and a circle air outlet is facing to the hole of flame discharge.

2, the novel combustion furnace of vortex according to claim 1 is characterized in that having a plurality of air inlets, and one of them air inlet is opened on upper furnace, and an air inlet is opened on the bottom of secondary combustion chamber.
