Abstract
The present invention discloses a kind of coal gasifying combustion furnace with double-sided grates to hold coal in between for high speed and high efficiency gasification and complete burning. The present invention produces little harmful and toxic gas, and has low running cost similar to that of coal burning chain furnace, efficient and clean burning effect similar to that of oil burning and gas burning furnace, and wide fuel adaptability capable of gasifying and burning various kinds of combustibles.
Description
Technical field:
The present invention relates to a kind of solid fuel ignition stove, more particularly, the present invention relates to a kind of coal gasifying combustion stove.
Background technology:
Domestic and international existing grate furnace all is that coal is placed on the plane grate of furnace bottom generally, and the single face air-supply is burnt under the fire grate.So far this mode of continuing to use is troubling the development of coal burning technology always, has caused the combustion intensity of stove and efficient lower, incomplete combustion, atmosphere pollution, a difficult problem such as steel consumption is high and can not maximize.
Summary of the invention:
The present invention improves domestic and international existing coal grate furnace technology, provide a kind of simple in structure, coal can be clipped in the middle carry out at a high speed, the gasification combustion furnace of the inside and outside two-sided fire grate of efficient burning, in order further to increase the contact interface first time between coal and the air, grate surface is arranged to nonplanar various geometric curved surfaces.This fire grate available metal material direct pouring or be welded.Its fire grate can be arranged to movable or fixed, and movable fire grate can adopt the fixedly back and forth flexible method work of port silver of whole rotation or big fire bars.Small-sized and specific (special) requirements arranged fire grate in the single on-plane surface also can only be set, this in the outer, base of fire grate be provided with the port tooth upwards erect (also played like this increase between coal and the air the first time contact interface effect).In order to prolong the life-span of fire grate, and make fire grate reliably working, fixed fire grate can adopt hollow-core construction water flowing cooling.Be provided with the vaporizer of a up-small and down-big cavity simultaneously on the two-sided fire grate in furnace chamber, big inclined-plane low spatial structure is adopted in the vaporizer bottom, small bore high spatial structure is adopted on top, be provided with a plurality of cross through hole or many as requested between vaporizer and the furnace chamber and be communicated with perps, vaporizer available metal material or nonmetallic materials are made.Also the gas outlet at furnace chamber is provided with a kind of burner that can mix with air, and burner available metal material or nonmetallic materials are made.
During the gasification combustion furnace operation, coal is sent up-small and down-big vaporizer to from coal filling hole, adopt the mechanism elder generation gas making of the little section thick charcoal layer of (directly) face reduction reaction of the thin charcoal layer oxidation reaction coupling of large interface, generate the high-temperature combustible gas body after burner and air mixed combustion, the semicoke that vaporizer gets off is clipped in the middle through two-sided on-plane surface fire grate and carries out high speed, efficient after-flame, becomes lime-ash and discharges.Thereby low cost, the high efficiency gasification, and combustion of coal have been finished.
Further specify the method for the present invention that realizes below:
Coal is clipped in the middle with inside and outside two-sided on-plane surface fire grate, air is sent into from this fire grate is two-sided, under this condition, the contact interface first time between coal and the air increases exponentially, realized that large interface approaches charcoal layer oxidation reaction, make the burning velocity of coal become several times to improve, simultaneously also efficient after-flame of coal.Up-small and down-big vaporizer in the furnace chamber makes coal be thin and tall shape because of the big space cavity of its ratio of height to diameter, so, has just realized the little section thick charcoal layer of (directly) face reduction reaction, and both arranged between the reactant sufficient time of contact; Small bore also improves the flow velocity of rising hot fluid, has supplied the quantity of carbon dioxide fast, has accelerated the heat convection between the reactant simultaneously again; Add the Fire Radiation of vaporizer outside, the temperature of vaporizer fuel bed is raise.The just inevitable speed of accelerating gasification reaction rapidly of these factors, make that gasification reaction carries out not only fully but also complete.High-temperature combustible gas body in that vaporizer generates burns with low excess air coefficient (1.05) through burner.Thereby the present invention finish the low cost of coal, at a high speed, gasification, and combustion efficiently, reached the purpose of clean utilization coal resources.
Benefit of the present invention is:
1. can become the burning velocity of several times raising fuel, the efficiency of combustion height, the combustion process toxic and harmful is few, has realized the clean utilization of coal.
2. fire grate adopts fixing big fire bars, and movable port silver can reduce the consumption of power, and stirring and disintegrating slag are effective simultaneously, favourable burning.
3. the fixed grate of fire grate adopts hollow-core construction water flowing cooling, and is safe and reliable, prolonged the service life of fire grate simultaneously again.
4. the wide adaptability of fuel can use fine coal and other solid combustible (solid waste) gasification, and combustion.
5. the integrated cost of this gasification combustion furnace is extremely low, the material consumption significantly reduces, the power consumption of gasification, and combustion process is 1/200 of domestic and international fluid bed and an air flow bed, the suitable cost of chain furnace almost, but combustion efficiency can reach the index of fuel oil, gas furnace high effect cleaning.Therefore, its extensively inside and outside existing various coal grate furnaces (comprising large-sized industrial kiln and large-sized boiler) of subrogate country and oil, steam stove.
