Abstract
The utility model pertains to melting furnace spraying guns and relates in particular to a synthetic fuel spraying gun used for industrial boiler or glass melting furnace. Central cavity of the spraying gun contains an inner slurry feeding pipe 2 and connects externally an air supply pipe 1 with an air inlet 3 on the side. The inner slurry feeding pipe 2 is positioned at front center of the spraying gun; inside the air supply pipe 1 are in turn mounted a female screw 4 for an air inlet duct; an outward conical inner nozzle 5 front end of which is provided a helically connected annular air inlet duct; an outward conical outer nozzle 6 connected helically to front end of the outward conical inner nozzle 5 and having an extending forehead and a retreating interior, which form an air inlet passage with a externally connected air cap 7. Realizing double-layer atomization, the utility model separates uniformly the gas flow within the fuel gun by adjusting the air cap and regulating the clearance between the outer and inner nozzles to control the ratio of air flow to slurry feeding and saves energy and lowers consumption by controlling the melting furnace temperature through fuel entrance regulation, thereby guaranteeing the safe, economic and stable operation of the melting furnace.
Description
Affiliated technical field
The invention belongs to the melting furnaces spray gun, particularly a kind of Industrial Boiler or glass melter use synthetic fuel spray gun of being used for.
Background technology
China is at the Industrial Boiler of usefulness or the Fuel lance of glass furnace use, and existing fuel lance can only be regulated oil pressure, the adjusting amount of fuel of oil gun according to the load variations of kiln, atomizing effect is bad, easy coking and blocking, and flow is unadjustable, make blast and air quantity wayward, influence is produced.
Summary of the invention
The objective of the invention is to overcome above technical deficiency, provide a kind of slurry, air quantity is adjustable, double-deck atomizing, the synthetic fuel spray gun of sufficient combustion.
Task of the present invention is that the center cavity of synthetic fuel spray gun is interior flow inlet, external side is provided with the air feed pipe of air inlet, the spray gun front central is provided with interior flow inlet, in the external air feed pipe, the nut that air inlet duct is set is installed successively, the leading section spiral connects the outer taper inner nozzle that the ring-type air inlet duct is set, and the outer taper outer nozzle of receiving in prolonging before taper inner nozzle front end spiral connects is outside formed air intake passage with external blast cap.
Synthetic fuel spray gun has following characteristics, at the air inlet duct of the external air intake nut of blast pipe, with the synthetic fuel mixing of flow inlet, enter the outer taper inner nozzle of front end, mix, realize double-deck atomizing through outer taper outer nozzle slurries, regulate blast cap, the ratio of controlling air quantity and supplying slurry is adjusted in the gap of the interior outer nozzle of control, and the interior air-flow of oil gun is evenly separated, control enters the fuel of melting furnaces, the control kiln temperature, energy-saving and cost-reducing, guarantee the melting furnaces safe and stable operation.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows the synthetic fuel spray gun section of structure.
Among the figure, 1-air feed pipe; The 2-flow inlet; The 3-air inlet; 4-air intake nut; The 5-inner nozzle; The 6-outer nozzle; The 7-blast cap
The specific embodiment
With reference to accompanying drawing 1, the external air intake nut 4 of the flow inlet of synthetic fuel spray gun, the connection of front end spiral is provided with the outer taper inner nozzle of ring-type air inlet duct, and the front end spiral connects outer taper outer nozzle 6, forms air intake passages with external blast cap 7.During synthetic fuel spray gun work, work as 2Mp
aPressure-air from blast pipe 3 air feed pipes 1, enter inner nozzle through air intake nut 4, the synthetic fuel that enters from flow inlet 2 mixes, front end through outer nozzle 6 with reach the synthetic fuel slurries that mix, spiral wind-force by outer nozzle 6 generations, make the atomizing once more of synthetic fuel slurry, spray the combustion chamber that enters glass melter from gun slot, fully burning.
Synthetic fuel spray gun is applicable to glass melter, cement plant melting furnaces and boiler of power plant.
