Abstract
An adjustable strengthening burning device of wide coal comprises a rear arch formed by a movable rear arch and a fixed rear arch. An air pipe is arranged on one side of a hearth of the fixed rear arch; the air pipe is connected with a sealed loose joint of a furnace fan air passage; a secondary air spray nozzle is arranged on the air pipe; and the air pipe is connected with an air pipe rotating driving system. The movable rear arch enables a furnace to adapt to different types of fire coal and to run under optimized state, and has high efficiency of the furnace. Cold air of the furnace fan air passage enters the hearth to strengthen burning, lower carbon content inside discharged smoke ash content, and simultaneously cool the air pipe and the secondary air spray nozzle. The air pipe rotating driving system enables the secondary air spray nozzle to face the hearth with a proper angle. Moreover, combination of the movable furnace arch and the secondary air spray nozzle enables the furnace to have higher adaptability for fire coal types and to obtain better running state.
Description
Technical field
The utility model relates to mechanical grate coal furnace, is that a kind of wide coal of mechanical grate coal furnace can be regulated intensified burning apparatus concretely.
Background technology
The energy-conservation key of mechanical grate coal furnace is burning, and the key of burning depends on chimney arch, and the arch of chimney arch and relevant physical dimension have determined the height of boiler efficiency.Existing fixed chimney arch mechanical grate coal furnace chimney arch designs at a certain coal, chimney arch can not change in running, usually the fire coal that when real work, adopts of boiler be difficult to design consistent, moreover China's coal is a lot, very different, in case coal-fired kind changes, will influence the boiler operatiopn effect, boiler efficiency is reduced, can not reach design objective.When the mechanical grate coal furnace of moving furnace arch changes in coal-fired kind, guarantee that by regulating moving furnace arch combustor exit flue gas flow rate, flame degree of filling and flame temperature reach desirable operational effect, but it also exists in the smoke evacuation phosphorus content of ash content higher, influences the drawback of utilization rate of coal.
Summary of the invention
The mechanical grate coal furnace that the utility model will solve existing moving furnace arch exists the phosphorus content of ash content in the smoke evacuation higher, influence the technical problem of utilization rate of coal, provide a kind of and can not only make boiler adapt to the variation of coal-fired kind and reach in desirable operational effect and the smoke evacuation ash content the lower wide coal of phosphorus content and can regulate intensified burning apparatus.
The utility model takes following technical scheme to solve above-mentioned technical problem: a kind of wide coal can be regulated intensified burning apparatus, comprise by movable rear arch and the fixing rear arch formed of rear arch, fixedly burner hearth one side of rear arch has airduct, airduct is connected with the loose joint of boiler fan air channel sealing, overfire air jet is arranged on the airduct, and airduct connects the airduct rotary drive system.
Force down or raise movable rear arch, change the arch and relevant physical dimension of rear arch, make boiler adapt to wide coal fuel, in the best condition operation.The cold wind in boiler fan air channel enters burner hearth through airduct, overfire air jet, and overheavy firing makes phosphorus content reduction in the smoke evacuation ash content, also airduct, overfire air jet is cooled off simultaneously.The airduct rotary drive system drives airduct, overfire air jet rotates, and adjusts overfire air jet with suitable angle subtend burner hearth.Moving furnace arch is strengthened combining of wind with secondary makes boiler get a greater increase to the adaptability of coal-fired kind, and running status is better.
Movable rear arch is hinged on the base of boiler side walls, and movable rear arch is fixedlyed connected with hinge axis, and the rear arch drive system connects hinge axis.What the rear arch drive system adopted is prior art, for example is that the driving handle of rear arch drive system is installed in outside the boiler side walls, and driving handle one end connects hinge axis, and the rotating drive handle makes movable rear arch rotate around the axis of hinge axis, forces down or raise movable rear arch; Or the drive motors of rear arch drive system makes movable rear arch rotate or the like around the axis of hinge axis through transmission mechanism.
Overfire air jet is a 15Cr1MoV heat resisting steel material.
The overfire air jet outside coats refractory material.Refractory material protection overfire air jet.
Refractory material is the high-alumina refractory concrete.
The airduct rotary drive system is in the boiler side walls outside.
The flexible handle of airduct rotary drive system connects an end of airduct.The angle of manual adjustments overfire air jet.
The motor of airduct rotary drive system connects an end of airduct through reduction gearing mechanism.The angle of motorized adjustment overfire air jet.
Airduct and fire grate plane parallel, and vertical with boiler side walls.
The utility model has the advantages that: movable rear arch makes boiler adapt to different types of fire coal, operation in the best condition, boiler efficiency height; The cold wind in boiler fan air channel enters burner hearth, and overheavy firing makes phosphorus content reduction in the smoke evacuation ash content, simultaneously airduct, overfire air jet is cooled off.The airduct rotary drive system makes overfire air jet with suitable angle subtend burner hearth.Moving furnace arch makes boiler higher to the adaptability of coal-fired kind with combining of overfire air jet, and running status is better.
