Abstract
The utility model relates to a car type combustion apparatus using coal-slurry or coke slurry as fuels, which belongs to combustion apparatuses using the coal-slurry or the coke slurry as fuels, more specifically the precombustion before the coal-slurry or the coke slurry enter the heating facility. The utility model comprises a precombustion chamber (3) and an air chamber (6) on the periphery. A refractory layer (5) is arranged between the precombustion chamber (3) and the air chamber (6). One end of the precombustion chamber is provided with a combustor (8), and the other end is a fire ejecting opening (2) connected with the heating facility (1). The combustor (8) is provided with a primary wind inlet pipe (10), and the wall of the air chamber (6) is provided with a secondary wind inlet (14). The utility model is characterized in that the refractory layer (5) is provided with a wind inlet pipe (4). The utility model can reduce heat dissipation to the greatest limit. Besides, the utility model has reasonable and uniform flame and air mixing. The heating facility can be conveniently removed, and thus, the utility model ensures convenient maintenance and ash removal.
Description
Technical field
The utility model belongs to water-coal-slurry, water coke slurry combustion apparatus, is specially the precombustion before the burnt slurry of water-coal-slurry, water enters heating facility.
Background technology
Water-coal-slurry is used widely as high-efficiency cleaning fuel; The burnt slurry of water is that calorific value is higher, sulfur-bearing is lower, ash content clean energy resource still less, but above product requires strict especially because of containing 30% above moisture to burning situation.There are following problem in existing water-coal-slurry, water coke slurry combustion apparatus: one, do not possess travelling performance, be unfavorable for igniting maintenance dedusting; Two, secondary wind enters from tangential slot, and is too concentrated, is unfavorable for that flame gas mixes; Three, because flame retardant coating should not be too thick thereby heat loss is bigger.
The utility model content
Technical problem to be solved in the utility model is in order to overcome above-mentioned defective, to provide a kind of and can reduce heat loss, more reasonable, the more uniform car-type water-coal-slurry of flame gas mixing, water coke slurry combustion apparatus to greatest extent.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: car-type water-coal-slurry, water coke slurry combustion apparatus, comprise precombustion chamber and peripheral air chamber thereof, be flame retardant coating between precombustion chamber and the air chamber, be provided with burner at an end of precombustion chamber, the other end is the bocca that connects heating facility, blast pipe is set on the burner one time, be provided with atomizer in the middle of the burner, the wall of air chamber is provided with the secondary wind inlet, and flame retardant coating is provided with blast pipe.
Described car-type water-coal-slurry, water coke slurry combustion apparatus, its blast pipe are a plurality of.
Described car-type water-coal-slurry, water coke slurry combustion apparatus, an end of its precombustion chamber is provided with peep hole, and peep hole is positioned at the top of burner; Peep hole is constant slope, also can insert oil burner oil drop fire.
Described car-type water-coal-slurry, water coke slurry combustion apparatus, an end of its precombustion chamber is provided with ash removing opening, and ash removing opening is positioned at the below of burner, is convenient to dedusting.
Described car-type water-coal-slurry, water coke slurry combustion apparatus, its air chamber below is equipped with land wheel.
Described car-type water-coal-slurry, water coke slurry combustion apparatus, its heating facility are Industrial Stoves or boiler.
Compared with prior art the beneficial effect that the utility model had is: because the utility model is provided with land wheel, ash removing opening, can remove heating facility very easily, add cheap fuel such as firewood from the bocca end, just can light a fire, cost reduces greatly, and easy to maintenance, is convenient to deashing; Because flame retardant coating is provided with a plurality of blast pipes, secondary wind enters preheating chamber at an angle from the flame retardant coating periphery, and radiant heat is sent to burner hearth again, has reduced heat loss to greatest extent, and it is more reasonable, more even that flame gas mixes.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is done further detailed narration:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
1 heating facility, 2 boccas, 3 precombustion chambers, 4 blast pipes, 5 flame retardant coatings, 6 air chambers, 7 peep holes, 8 burners, 9 atomizers, 10 blast pipes, 11 ash removing openings, 12 land wheels, 13 ground rails, 14 secondary wind inlets
Shown in Fig. 1-2: an end of precombustion chamber 3 is provided with burner 8, the other end is the bocca 2 that connects heating facility 1, blast pipe 10 is set on the burner 8 one time, be provided with atomizer 9 in the middle of the burner 8, the periphery of precombustion chamber 3 is an air chamber 6, the wall of air chamber 6 is provided with secondary wind inlet 14, is flame retardant coating 5 between precombustion chamber 3 and the air chamber 6, and flame retardant coating 5 is provided with blast pipe 4.Root wind enters through blast pipe 10 from air chamber 6, and secondary wind enters air chamber 6 by the outside through secondary wind inlet 14, rotates into precombustion chamber 3 through oblique blast pipe 4, and precombustion chamber 3 internal flame gas are rotated at a high speed; Because wind is 360 ° and injects from the periphery that it is more even that flame gas is mixed, and is more conducive to burning; Precombustion chamber 3 is sent back to precombustion chamber 3 again by the radiant heat that flame retardant coating 5 is radiated air chamber 6 simultaneously, has reduced heat loss to greatest extent.
