Description
Technical field
The present invention relates to a kind of aluminum ingot melting furnace of continous way heating, in particular by the aluminum ingot melting furnace with heat radiation Yu Convective Heating mode of biomass fuel.
Background technology
Existing aluminum ingot melting furnace species is more, mainly has oil burner, gas furnace and coal furnace etc. for the fuel that it is used, and the mode of heating up is generally included：Heat radiation heating is heated with thermal convection current,Considered from the contribution of metal molten heat,The latter is much bigger than the former,Therefore,With regard to the structure of current smelting furnace,The reachable part of the high-end thermal convection current of stove is the position heated raw material and make its fusing,And bottom is then the position of storage alloy solution,It is easy to upward in view of the most advection heat of heat transfer is accounted for,And the liquid metal for being in bottom can only maintain liquid by hot spoke heat,Generally,The heating burner noz(zle) for maintaining alloy to keep liquid without solidification is provided near the upper surface of bottom liquid alloy as alloy melting furnace,This heating burner noz(zle) is main heating burner noz(zle),And the auxiliary combustion nozzle for further enhancing heat is set in thermal convection current rising passway,What this existing main burning heated nozzle had the stove use of auxiliary combustion heated nozzle again is all oil burner or gas furnace,Reason is that the combustion flame size of this two class A fuel A is easily controlled,So that liquid metal maintains have a rational heat distribution in terms of not solidifying with the solid metallic persistently size of fusing amount,But,For the green fuel of the relatively broad use in current rural area --- for the biomass fuel that straw or sorghum make,Above-mentioned body of heater is just no longer appropriate for.In view of this, it is necessary to which collateral security aluminium ingot heating fusing keeps noncondensing angle to set out with fusing metal, and design is a kind ofIt is newThe furnace binding of aluminium ingot fusing, especially with the aluminum ingot melting furnace of biomass fuel, current this problem is not solved effectively.
The content of the invention
The purpose of the present invention is that the above-mentioned deficiency for prior art, there is provided a kind of melting furnace of utilization biomass fuel heating fusing aluminium ingot.
The purpose of the present invention is achieved through the following technical solutions
A kind of melting furnace of utilization biomass fuel heating fusing aluminium ingot, is made up of 4 regions, and 1st area is raw material heating part, and fire grate is supported comprising furnace charge（4）, charging aperture and furnace charge burner hearth being accommodated, 2nd area are furnace bottom melting tank part, including hearth of melting furnace（1）, radiate heat reflection plate（2）And advection heat computer heating control door（3）, 3rd area be combustor section, including flame export control door（5）, combustion chamber stove grate（6）, fuel extruding dredge plate（7）, side wall burning oxygen supply air-line system（11）, fire grate burning oxygen supply air-line system（12）, 4th area are part of the fuel supply, including may be reversed box-shaped fire grate（8）, fuel filler bucket（9）, fuel propulsive systems（10）, box-shaped fire grate preheating air-line system（13）, general characteristic is that the arrangement in 4 regions is L-shaped, 1st area L-shaped structure highest part, the radiation heat reflection plate in 2nd area（2）, Convective Heating control door（3）With hearth of melting furnace（1）In the lower floor in 1st area, the i.e. lower half of L vertical portions, 3 area's furnace charge flame export control doors（5）, combustion chamber stove grate（6）, fuel extruding dredge plate（7）, burning oxygen supply airduct system（11,12）, one end docks with 2nd area, and the other end and 4 area's fuel may be reversed box-shaped fire grate（8）, fuel filler bucket（9）, fuel propulsive systems（10）, box-shaped fire grate preheating air-line system（13）Constitute a combustion chamber body of heater.
Beneficial effect：
For 2 area's hearth of melting furnace（1）Top sets radiation heat reflection plate（2）The radiant heat of 3 area combustion flame exports can be reflected back hearth of melting furnace（1）In, this is than radiationless heat reflection plate（2）In the case of acquired radiant heat it is many, advection heat computer heating control（3）Folding can both control the number that convection heat heats to 1st area, furnace bottom hearth of melting furnace can be kept again（1）Temperature height change, flame export control door（5）Folding can realize that to 2nd area and the how many control of 1st area heat supply and plate is dredged in the extruding of the fuel on 4 area tops（7）The loose biomass fuel of density can be produced extruding, to increase the density of feeding fuel, may be reversed box-shaped fire grate（8）The bottom of flattening Shi Shi 4 area parts of the fuel supply keeps complete, upset erect after just can carrying out horizontal blowing, that is, play a part of to be fuel preheating, burning oxygen supply, while improving flame combustion chamber flame intensity again, radiate heat reflection plate（2）Under stove wall be that the heating of liquid metal can be so more beneficial for bottom angled with insulation, combustion chamber stove grate（7）It is divided into 2 sections, 2 sections of fire grate gap densitys are different, and just splaying is more dredged for burning, be conducive to the ventilation of macro particles fuel with it is combustion-supporting, tapered into burning tip fuel particle, the closeer fire grate of density arrangement can keep ventilation to ensure that the loss that smaller particle fuel will not be too early.
The aluminum ingot melting furnace composition of biomass fuel heating is simple, there is good construction and system integration feature, it is easy to debug, O＆M, in the industry with good promotional value.
