Abstract
The utility model relates to an adjustable type powder-shaped fuel spray gun which comprises a delivery pipe and a combustion nozzle, wherein the delivery pipe is used for delivering fuel and combustion-supporting air. The delivery pipe is composed of a fuel pipe and an air blast pipe, the fuel pipe is used for delivering the fuel, the air blast pipe is sleeved outside the fuel pipe, and an air blast channel is formed between the air blast pipe and the fuel pipe. The combustion nozzle is connected with the delivery pipe, and an adjusting ring is arranged between the combustion nozzle and the delivery pipe. The adjusting ring is provided with an oil transporting hole and a plurality of adjusting air grooves which are arranged on the surface of the outer side of the adjusting ring, the oil transporting hole and the fuel pipe are matched in a connection mode, and the adjusting air grooves and the air blast channel are matched. The adjustable type powder-shaped fuel spray gun has the advantages of enabling fuel and air to be atomized secondarily in high pressure, and enabling combustion to be sufficient. Meanwhile, the length of flame can be adjusted by pressure, so that powder fuel can have good combustion time, combustion is sufficient, released heat value is high, residual is little, drainage is little, and the adjustable type powder-shaped fuel spray gun has high environmental-friendly performance.
Description
Technical field
The utility model relates to a kind of burner, is specially a kind of adjustable dusty fuel spray gun.
Background technology
Existing boiler is generally sent into the powder fuels such as coal dust or oil plant and a wind in the boiler by burner and is burnt in actual motion.The problem that such method of operation exists is that primary air flow is limited, and the powder fuel needed enough oxygen that burns can not be provided, and efficiency of combustion is low, can not discharge fully the calorific value of fuel, residual many after the burning simultaneously, and exhaust emission is serious.In addition, according to the characteristics of burning feeding, powder fuel carries the pressure that needs low, to keep the enough heating flame time, is convenient to powder fuel is fully heated, and makes burning more abundant; And the pressure of air-supply should be relatively large, and enough oxygen so just can be provided; Existing burner can't head it off; Moreover existing burner can't provide whirlwind, and also uncontrollable air-supply air-flow angle is regulated to carry out firepower, regulates length and the diameter of flame.Therefore need to improve existing burner.
The utility model content
The purpose of this utility model is the deficiency that exists for the above existing burner, provides a kind of efficiency of combustion high, the adjustable dusty fuel spray gun that wind-force can be regulated.
The utility model is achieved in that adjustable dusty fuel spray gun, comprise carrier pipe and burner noz(zle) for delivery of fuel and combustion air, described carrier pipe forms air-supply passage by forming for delivery of the cartridge of fuel, the ajutage that is enclosed within the described cartridge outside between described ajutage and the described cartridge; Described burner noz(zle) is connected with described carrier pipe, is provided with adjustable ring between described burner noz(zle) and described carrier pipe; Be provided with oil transportation hole and some adjusting wind grooves that is positioned at outer surface on the described adjustable ring, described oil transportation hole and described cartridge are in mating connection, and described adjusting wind groove matches with described air-supply passage.By regulating the oil transportation hole on the adjustable ring and regulating the wind groove and can regulate flame length and burning time etc.
Described burner noz(zle) is inboard to be formed with blending space with adjustable ring, and described oil transportation hole and adjusting wind groove converge with blending space and be communicated with, and fuel and air are mixed in blending space.
The spout internal diameter of described burner noz(zle) is less than blending space internal diameter, can make fuel and air mixture form the high-pressure spray state, fully mixes with air in blending space.
Described adjusting wind groove can be helical form, and combustion air can form whirlwind under the guiding of adjusting wind groove, and the raising air mixes with fuel.
Described ajutage is provided with combustion air inlet, is used for being connected with air duct.
Compared with prior art, the advantage that has of the present utility model is: by the outlet of two sections small-bores, can make fuel and air carry out secondary high-pressure atomizing, and under the mixing of whirlwind and fuel, make burning more abundant; And flame length can be regulated by pressure, makes powder fuel can have better burning time, sufficient combustion, and it is high to discharge calorific value, and residual few, and discharging is also few, has the very high feature of environmental protection.
Description of drawings

Fig. 2 is the A-A section sectional structure chart of the adjustable dusty fuel spray gun of the utility model;
Fig. 3 is the structure chart of adjustable ring.
The specific embodiment
Below in conjunction with accompanying drawing the adjustable dusty fuel spray gun of the utility model is described in detail.
Adjustable dusty fuel spray gun, as depicted in figs. 1 and 2, comprise carrier pipe 1 and burner noz(zle) 2 for delivery of fuel and combustion air, described burner noz(zle) 2 is connected with described carrier pipe 1, between described burner noz(zle) 2 and described carrier pipe 1, be provided with adjustable ring 3, be used for regulating the conveying of high pressure combustion air and fuel.Described carrier pipe 1 forms air-supply passage 13 by forming for delivery of the cartridge 11 of fuel, the ajutage 12 that is enclosed within described cartridge 11 outsides between described ajutage 12 and the described cartridge 11.As shown in Figure 3, be provided with oil transportation hole 32 and some adjusting wind grooves 31 that is positioned at outer surface on the described adjustable ring 3.Described adjusting wind groove 31 arranges some as the case may be, and it is used to form high-pressure blast.Described oil transportation hole 32 and described cartridge 31 are in mating connection, and described fuel is by described oil transportation hole 32; Described adjusting wind groove 31 matches with described air-supply passage 13, and described combustion air is by described adjusting wind groove 31.By regulating the oil transportation hole 32 on the adjustable ring and regulating wind groove 31 and can regulate flame length and burning time etc.
Described burner noz(zle) 2 inboards are formed with blending space 5 with adjustable ring, and described oil transportation hole 32 and adjusting wind groove 31 converge with blending space 5 and be communicated with, and fuel and air are mixed in blending space 5.Spout 21 internal diameters of described burner noz(zle) 2 are less than blending space 5 internal diameters, can make fuel and air mixture form the high-pressure spray state, fully mix with air in blending space 5.Wherein, described adjusting wind groove 31 can be helical form, and combustion air can form whirlwind under the guiding of adjusting wind groove, and the raising air mixes with fuel.Be provided with combustion air inlet 4 at described ajutage, be used for being connected with air-supply passage 13.
By the outlet of two sections small-bores, can make fuel and air carry out secondary high-pressure atomizing, and under the mixing of whirlwind and fuel, make burning more abundant; And flame length can be regulated by pressure, makes powder fuel can have better burning time, sufficient combustion, and it is high to discharge calorific value, and residual few, and discharging is also few, has the very high feature of environmental protection.
