Abstract
The utility model relates to a flow guide device of a blast furnace gas burner for a boiler, which belongs to the technical field of a burner of a gas fired-boiler. The flow guide device comprises a fixing ring, a rotary flow blade, a gas blade fixing ring and a coke oven gas ignition stable combustion pipe, wherein the rotary flow blade is welded with the gas blade fixing ring and the fixing ring to form a flow guide piece; the flow guide piece is fixed in a blast furnace gas outlet pipeline; the gas blade fixing ring and the fixing ring form internal sleeving type concentric circles; the fixing ring is fixed on the coke oven gas ignition stable combustion pipe; and the diameter of the coke oven gas ignition stable combustion pipe is the same as the diameter of the fixing ring. The utility model has the advantages that the problems of coking at the burner outlet, difficult cleaning and the like are solved; the intensified gas-gas mixing of the burner is achieved; the gas-gas mixture can reach the firing concentration timely; the firing time is shortened; and the purpose of stable combustion is achieved.
Description
Technical field
The utility model belongs to the burner for gas boiler technical field, and a kind of boiler blast furnace gas burner device is provided especially.
Background technology
In metallurgy industry, the comprehensive utilization of blast furnace gas is comparatively paid attention to, need utilize boiler that energy conversion is utilized in order to reduce directly to diffuse.Coal gas side and the air side in the blast furnace gas burner all is equipped with swirl vane in its combustion system of gas fired-boiler at present, the guide vane of each blast furnace gas burner is 18, the angle of inclination is 45 ℃, makes the rotation ejection of coal gas and air, and is contained in anterior flame holder and mixes strongly and burn.But because coal gas band water and higher dustiness, the blast furnace gas ignition point is too near apart from the distance of the swirl vane of blast furnace gas ejiction opening, cause the swirl vane temperature drift, when containing the blast furnace gas process swirl vane of a large amount of dust, dust is bonded on the swirl vane after melting, and causes blast furnace gas burner outlet coking, influence high gas firing through-current capacity, can limit boiler output when serious, be forced to the cleaning of blowing out decoking, have certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler with blast furnace gas burner device, improves boiler combustion efficiency, solves burner outlet coking, is difficult to security hidden trouble such as cleaning.
Boiler blast furnace gas burner guiding device comprises retainer ring, swirl vane, coal gas vane ring, coke-stove gas ignition smooth combustion pipe; Swirl vane and coal gas vane ring, retainer ring are welded to connect, be welded into conducting element, be fixed in the blast furnace gas outlet conduit, coal gas vane ring and retainer ring are the inner cased type concentric circles, retainer ring is fixed on the coke-stove gas ignition smooth combustion pipe, and the diameter of coke-stove gas ignition smooth combustion pipe is identical with the diameter of retainer ring.
The center of coal gas vane ring is a coke-stove gas ignition smooth combustion pipe, is the ignition smooth combustion spout.
Swirl vane is fan-shaped, and material is 1Cr18Ni9T, and fan-shaped last diameter is 392mm, and following diameter is 101mm, highly is 147mm.
Evenly arrange 6 swirl vanes between coal gas vane ring and retainer ring, swirl vane and coke-stove gas ignition smooth combustion pipe clamp angle are 60 degree.
The novel suitable position of blast furnace gas pipeline outlet that is installed in of this use, the steady burning-point fire-fighting of coke-stove gas mouth invariant position, make the distance lengthening of the ignition point of swirl vane and blast furnace gas, the cooling of the blast furnace gas that swirl vane can not caught fire and away from the soot particle that melts reduces the bonding of soot particle at swirl vane.By the through-current capacity of high gas control valve control blast furnace gas, guarantee the smooth combustion of blast furnace gas during operation, solved burner outlet coking, the difficult problem of cleaning.Use after this device, boiler improves greatly with the through-current capacity of burning blast furnace gas, has guaranteed that the full load of boiler is exerted oneself, and has also avoided the grievous injury that unit durability is produced because of frequent start and stop stove decoking simultaneously.
Advantage of the present utility model is mixed at the strong gas gas of burner, makes gas gas in time reach the concentration of catching fire, and shortens ignition time, reaches the purpose of smooth combustion.
