Abstract
The invention provides a kind of new joint combustion technology and device thereof, volatile matter in the coal combustion process and fixed carbon are divided into two stage burnings, to improve combustion atmosphere, improve its efficiency of combustion, reach the high effective smokeless burning of bituminous coal, provide a kind of new high-effect, the burner of simple and feasible for promoting moulded coal.The present invention is applicable to small-sized industrial boiler, back yard industry kiln, is applicable to boiler for domestic and all life cooking stoves.
Description
The present invention relates to a kind of new solid fuel ignition technology and device thereof.
Existing is small-sized industrial boiler, back yard industry kiln and the domestic life cooking stove of fuel with the coal, all continues to use and is just burning method, that is: the face that catches fire is descending by the interrupted coal in top.This method is at the coal initial stage soon, and burner hearth is to burn under the situation of lack of air, and performance part is separated out for paroxysmal, and combustion atmosphere is uncontrollable, and the part fugitive constituent is drained with flue gas, and not only efficiency of combustion is low, and contaminated environment.
Task of the present invention has provided a kind of new two-stage combustion technique, and the combustion process of fugitive constituent and fixed carbon is divided into two sections, organizes combustion atmosphere different, that adapt, improves efficiency of combustion, and smoke effect is arranged.Task of the present invention also is two-stage combustion technique is provided and a kind of function admirable of designing, the burner of simple and feasible.This device (burner) is widely used for small-sized industrial boiler, back yard industry kiln, domestic life boiler and all Civil energy-saving cooking stoves.
The present invention finishes with following method: bunker coal is divided into two sections organizes burning.That is: the fugitive constituent of fuel being separated out burning and fixed carbon burns and separately to carry out, according to fugitive constituent separate out the burning and the burning of fixed carbon different process, the different atmosphere that adapts is provided, minimizing interferes with each other, make main burning composition fixed carbon have stable burning condition, make whole combustion process keep nominal situation.
Bunker coal is at first finished fugitive constituent and is separated out burning, enter the fixed carbon combustion zone again after forming semicoke or coke, under the thermal condition that adapts, smooth combustion, adopt the method for this two stage combustion, obviously improved the work atmosphere of whole combustion process effectively, more rational tissue burning, improve efficiency of combustion, eliminate black smoke.
Adopt reverse burning machine to form the combustion chamber, changed the paroxysmal that fugitive constituent separates out and separated out for stable, make the fugitive constituent ratio of combustion more abundant, but still can't make fixed carbon that a combustion atmosphere that adapts is arranged, inert material (ash content) is all the time on the top of combustion chamber simultaneously.Top, combustion chamber is the high-temperature region, so be easy to slagging scorification, and has destroyed the grate firing process, again because ventilative inconsistency, and the destruction with gasification of also can causing burning, efficiency of combustion decreases.
The two stage combustion mechanism of the tissue burning that utilization fugitive constituent and fixed carbon separate, design is by the volatilization chamber of axes intersect and the combustion chamber of carbon combustion chamber combination.
Below with reference to accompanying drawing its device is described in further detail:
With reference to accompanying drawing, form carbon combustion chamber (1) by fire grate (3) and furnace chamber, volatilization chamber (2) is in carbon combustion chamber (1) one side, its axes intersect; Carbon combustion chamber (1) be a vertical configuration, and the chamber (2) of volatilizing is horizontal, or the end is inclined upwardly and installs bell (7) (as shown in Figure 1), and end cap (6) (as shown in Figure 2).
Bunker coal adds from volatilization end, chamber (5), by annular air compartment (6) air supply, coal is in the heating of volatilization chamber, drying, volatilization, burning, be pushed into charcoal combustion chamber (4) after forming coke, entering carbon combustion chamber is the coke that has abundant heat to prepare, supply with carbon burning from fire grate (3) underfeed through the air that slag gives hot capacity, the ash content slagging scorification of formation is discharged from the bottom fire grate.
Discharge and imperfect combustion gas and carbon particle mixing burning once more from secondary air hole (2) from the air that secondary air duct (1) blasts.
Device shown in Figure 1 is a raw coal burner, except that burning raw coal, also can burn coal briquette.
Device shown in Figure 2 is the honeybee coal burner, except that burning common garden shape honeybee coal, also can burn square honeybee coal.
Fig. 1, microburner shown in Figure 2 can not installed reinforced propulsive mechanism, and equipment is simple, and is easy to operate.
The alumina silicate fibre heat-insulation layer is all laid in the burner periphery of practical application, and shell is metal structure, or cement gives structural member processed, according to the purposes difference, can be designed to the series of products of different size, produces by factory is specialized.
Claims (7)
1, a kind of solid-fuelled two-stage combustion technique is characterized in that the fugitive constituent of bunker coal and fixed carbon are divided into the method for two stage burnings.
2, by the mode of claim 1 regulation, the burner of being made up of carbon combustion chamber (4), volatilization chamber (5) secondary air duct (1), secondary air hole (2), fire grate (3) it is characterized in that volatilizing chamber and carbon fires the axes intersect and the UNICOM of chamber.
3, by the regulation of claim 2, volatilization chamber (5) is characterized in that the periphery is provided with annular passage (6).
4, by claim 1 and 2 regulation, the angle of cut of it is characterized in that volatilizing chamber and carbon combustion chamber axis is 60 °～90 °.
5, by claim 2 regulation, fire grate (3) is characterized in that the inclination angle is 0 °～60 °.
6, by the regulation of claim 2, installing cover plate (7) in volatilization end, chamber (5) can be closed after it is characterized in that adding bunker coal.(as shown in Figure 1).
7,, know that honeybee coal volatilization shown in Figure 2 end, chamber is furnished with end cap (6) and it is characterized in that to regulate intake or to bank up a fire by the regulation of claim 2.
