Description
Technical field
The utility model relates to the aggregate oven dry and the burner for heating of a kind of asphalt mixing plant, dry powder mixing plant, asphalt heat recycling equipment, specifically is a kind of oil/coal dual burner.
Background technology
Pitch mix equipment main burner as selecting at present to use mainly contains two kinds of oil burner and coal burners, and the fuel that two kinds of burners adopt is different and cut both ways, and under different situations, enterprise can select to use according to actual needs.In order selectively to use burner, enterprise must dispose oil burner and coal burner respectively, and cost of equipment has high input, and uses also extremely inconvenience.
The application of existing pulverized coal combustion is also very not general.Even there is a small amount of pitch mix equipment to adopt coal burner, also mostly is single channel, two passage coal burners, this burner is because bulky, air channel quantity shape of chamber structure complexity and relative position unreasonable, slagging scorification is serious, scarfing cinder is difficult, combustion furnace stove brick is short fragile service life, combustion instability, temperature are restive, adapt to coal few, pollute number of drawbacks such as big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of oil/coal dual burner is provided, can select to use fuel oil or coal dust to act as a fuel at same burner according to actual needs, oil burner, coal burner are united two into one, it is little, easy to use that tool takes up space.
Another purpose of the present utility model is: improve in the air channel to coal burner, has improved combustion stability, and coal dust can be burnt cmpletely, reduces the slagging scorification phenomenon to greatest extent.
The utility model adopts following technical scheme:
Oil/coal dual burner is characterized in that: comprise the bellows that are arranged at the rear portion, combustion chamber and be set in wind coal pipe, oil gun in the wind box duct from inside to outside successively; The wind coal import of described wind coal pipe rear end is connected by the wind coal machine of conveyance conduit with the outside; The described oil gun port of export is equiped with atomizer, and the hydraulic fluid port of oil gun rear end is connected by the oil pump of oil pipe line with the outside.
Be arranged with one time airduct between described wind coal pipe and the oil gun, the air inlet of an airduct rear end is connected by the clean blower fan of ajutage with the outside; Described oil gun is set with sleeve pipe outward, is equiped with the wind deflector that produces eddy flow wind between sleeve pipe and an airduct, makes the air-out of an airduct form eddy flow wind effect by wind deflector.
Be arranged with secondary air channel between described wind coal pipe and the bellows inwall, the air inlet of an airduct rear end is connected by the clean blower fan of ajutage with the outside.
Described bellows air opening end and the fan housing that is set with taper, the front portion of this fan housing is provided with the hollow tube-shape combustion-supporting that two ends connect, the described combustion chamber of the inner formation of this combustion-supporting; Be arranged with the taper stable flame pan that is fixed on the secondary air channel air opening end in the fan housing, the spacing between stable flame pan periphery and the fan housing inwall forms the eddy flow wind air outlets that the direct current wind air outlet, the stable flame pan that are communicated with wind box duct are provided with most connection wind box ducts.
Be equiped with igniter on the described stable flame pan.
The utility model adopts coal dust as the course of work of burner fuel to be: behind the firing point firearm, the wind pressure of coal dust by wind coal pipe is transported in the combustion chamber that combustion-supporting constitutes and ignites, by the time after the coal dust smooth combustion, igniter stops oil spout, and burner is fuel smooth combustion with the coal dust.During coal dust firing, airduct, secondary air channel, bellows are respectively it wind, secondary wind, tertiary air are provided simultaneously, be the additional enough oxygen of burning of coal dust, make the steady combustion state that coal dust firing is more abundant, flame reaches the best, reduce the slagging scorification phenomenon to greatest extent.For high-volatile bituminous coal, can suitably increase the air intake flow velocity of an airduct, with the length of compression recirculating zone; Suitably reduce the eddy flow wind air quantity of secondary air channel, and strengthen the direct current secondary air flow, make flame reach best steady combustion state, and make second-time burning more complete, thereby make flame reach optimum state.For low-volatite bituminous coal or anthracite, suitably reduce the distinguished and admirable speed of direct current that airduct provides, with the diameter and the length of expansion recirculating zone, the tertiary air that bellows provide replenishes enough oxygen; Suitably increase eddy flow secondary eddy flow wind flow, and reduce the direct current secondary air flow, make flame reach best steady combustion state, and make second-time burning more complete, thereby make flame reach optimum state.This burner is set with the oil gun of band dress atomizer in an airduct, can utilize fuel oil to replace coal dust as burner fuel, thereby realizes coal, oily dual-purpose; During use, close airduct one time, start oil pump to the oil gun fuel feeding, utilize igniter point oil fuel to get final product, secondary air channel, bellows air feed together are combustion-supporting and control fiery type.
The utlity model has following advantage:
One, above-mentioned oil/coal dual burner unites two into one coal burner and oil burner, can independently select to adopt fire coal or fuel oil to act as a fuel at same burner, realization kerosene is dual-purpose, significantly reduce the cost of equipment input, reduce production costs, improve the competitiveness of product in market.When two, this burner utilizes coal dust to act as a fuel burning, airduct, secondary air channel and a bellows while air feed, make coal dust can obtain burning cmpletely, thereby reduced the slagging scorification phenomenon, the a small amount of slagging scorification that exists also is loose condition (of surface), can be attached on the furnace wall, cleaning has prolonged service life easily; The 3rd, because the independent controllability in each air channel can adapt to the many coal burnings from the low volatile to the high volatile.
