The existing burner providing thermal source for Suspension Roaster for Aluminium Oxide, is made up of current-carrying tube, valve and burner, structure
Simple and crude.Problem present in production is that gas or liquid fuel transporting resistance are larger, and the mechanically and chemically heat loss of fuel is big,
The thermal efficiency is low, and unit product heat consumption is high, and heat source temperature is unstable；Fuel leads to fuel to fire with air it cannot be guaranteed that reasonable mixture ratio
Burn insufficient, easily form nitrogen oxides, atmosphere pollution；When gas fuel pressure fluctuates, easily there is " tempering " deflagration phenomenon.
Utility model content
For solving the technical problem that above-mentioned existing burner exists, task of the present utility model is to suspend for aluminium oxide to roast
Burn stove provide a kind of fuel combustion abundant, the thermal efficiency is high, heat source temperature is stable, gaseous fuel be not susceptible to " tempering " burning fill
Put.
Complete this utility model Suspension Roaster for Aluminium Oxide burner of above-mentioned task, including before and after the meter that is sequentially connected
Amount adjustment unit, fuel allocation unit and fuel element.
Described metering adjustment unit, including the Hand-operated butterfly valve being sequentially arranged at by tandem on current-carrying tube, effusion meter, gas
Dynamic stop valve I, pneumatic control valve and pneumatic cut-off valve II, the current-carrying tube between pneumatic control valve and pneumatic cut-off valve is installed
Atmospheric valve；
Described fuel allocation unit, including the ring pipe being connected with described metering adjustment unit by current-carrying tube, ring pipe
There is one group along the equally distributed arm of ring pipe, each arm is connected with metal hose, it is single with burning that metal hose passes through bend pipe
Unit connects, and bend pipe is provided with hand-operated valve and pressure gauge；
Described fuel element, including the burner seat connecting with the bend pipe of described fuel allocation unit, there is burning burner seat front end
Mouth, it is indoor that burner is placed in roaster burning.
The rear portion of described burner is cylindrical shape, and its inwall is machined with helix；The head of burner expands into ellipsoid, thereon
There is equally distributed cone barrel aperture.
The advantage of this utility model burner is：
1st, use this utility model device to provide thermal source for Suspension Roaster for Aluminium Oxide, the governor motion of device can be passed through at any time
, it is ensured that fuel is reasonable with air stoichiometry, burning is abundant, heat source temperature good stability, the thermal efficiency for the flow of regulation fuel and pressure
Height, reduces unit product heat consumption.
2nd, the burner inwall of this utility model device is machined with helix, and burner head is ellipsoid, and with uniformly opening
If cone barrel aperture, be conducive to fuel to be fully contacted with primary air and mix, further improve the thermal efficiency.
3rd, fully, nitrogenfree oxide produces, and does not result in pollution to air for fuel combustion.
4th, when gas fuel pressure occurs fluctuation, device will not occur " tempering " and deflagration phenomenon.
