Abstract
The present invention relates to a kind of coal burner for grain drying tower air stove, belong to coal burner.One time ajutage is attached with coal dust shower nozzle by flange, coal dust shower nozzle is fixing with maintenance door to be connected, maintenance door is connected with burner body by folding, hands is taken turns, screw telescopic bar, guide vane wheel and air deflector link together and are installed in coal dust shower nozzle, burner body from-inner-to-outer is high-temperature flame-proof layer and water-cooled layer respectively, water pump is positioned in water tank, this water pump is connected with water-cooled layer by water pipe, secondary blast pipe is connected with burner body, fix internal with burner body of wind deflector is connected, and it is positioned at the oral area of secondary blast pipe, diesel oil ignitor is positioned at the outside of fire hole.Advantage is novel structure, working stability, is easily maintained, and the coal dust time of staying in burner high temperature district is long, thus efficiency of combustion is high, and its efficiency reaches more than 95%, and burning is completely, energy-efficient.
Description
Technical field
The invention belongs to a kind of coal burner, refer in particular to the coal burner for grain drying tower air stove.
Background technology
Grain heat-drying drying tower for many years has been used up chain-type air stove, and chain-type air stove burn-off rate is low, thermal effect
Rate only has about 70%, by changing its combustion system, becomes coal dust firing mode, can improve the burn-off rate of coal, can reach 98%
Left and right, the thermal efficiency brings up to about 95%.The most existing coal powder burner, for air quantity, the length of flame and flow
Control be difficult to apply in the transformation of grain heat-drying air stove, make up to drying requirement.
Summary of the invention
The present invention provides a kind of coal burner for grain drying tower air stove, to solve existing coal dust firing dress
Put and be not suitable for the problem that grain drying tower air stove uses.
The present invention adopts the technical scheme that: one time ajutage is attached with coal dust shower nozzle by flange, coal dust shower nozzle
Fixing with maintenance door being connected, maintenance door passes through folding and is connected with burner body, handwheel, screw telescopic bar, guide vane wheel and lead
Stream device links together and is installed in coal dust shower nozzle, and burner body from-inner-to-outer is high-temperature flame-proof layer and water-cooled layer respectively,
Water pump is positioned in water tank, and this water pump is connected with water-cooled layer by water pipe, and secondary blast pipe is connected with burner body, wind direction water conservancy diversion
The plate fixing oral area that be connected and be positioned at secondary blast pipe internal with burner body, diesel oil ignitor is positioned at outside fire hole
Portion.
It is an advantage of the invention that novel structure, working stability, be easily maintained, the circulation of water-cooled layer during burner operation simultaneously
The heat of water can collection and utilization, during the heating of this coal burner, ramp-up time shortens, and the thermal efficiency is high, and igniting easily, heats up
Hurry up, work efficiency greatly improves；Air output, coal-fired input quantity can be altered as desired, and can be at regulated in wider range furnace temperature and fire
Flame length, meets and is actually needed；Coal burner internal temperature field is uniform.The coal dust time of staying in burner high temperature district
Long, thus efficiency of combustion is high, its efficiency reaches more than 95%, and burning is completely, energy-efficient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
One time ajutage 12 is attached with coal dust shower nozzle 2 by flange 7, and coal dust shower nozzle 2 is fixing with maintenance door 4 to be connected,
Maintenance door 4 is connected with burner body 6 by folding, and handwheel 8, screw telescopic bar 9, impeller inducer 1 and air deflector 10 are connected to
Together and be installed in coal dust shower nozzle 2, burner body 6 from-inner-to-outer is high-temperature flame-proof layer 15 and water-cooled layer 16, water pump respectively
18 are positioned in water tank 13, and this water pump 18 is connected with water-cooled layer 16 by water pipe 17, and secondary blast pipe 5 is connected with burner body 6,
The wind deflector 14 fixing oral area that be connected and be positioned at secondary blast pipe 5 internal with burner body 6, diesel oil ignitor 11
It is positioned at the outside of fire hole 3.
Wind powder mixture is spurted in coal dust shower nozzle 2, after impeller inducer 1 and air deflector 10 by an ajutage 12
Shunting also mixes with secondary blast, controls handwheel 8 and drives the movement of screw telescopic bar 9 to keep impeller inducer 1 and air deflector 10
Position, thus control the swirl strength of wind powder mixture, thus regulate the mixing of primary and secondary air, make wind powder mix homogeneously with
And the enough pulverized coal particle suspension stay time, after diesel oil ignitor 11 is lighted, flame is along high-temperature flame-proof layer 15 rotation spray
Injection, water pump 18, by the water pump of water tank 13 to water-cooled layer 16, is reduced the temperature of high-temperature flame-proof layer 15 by the recirculated water of water-cooled layer 16,
Ensure the safety and stability of burner.
