Background technology
Vacuum burner is that burning fuel to produce the equipment of heat, for example, is used for fire in military hardware, commercial production
Arrow igniting, metal smelting and process chemical substance.The vacuum burner before designing, without throttling arrangement, needs to couple special
Choke valve, increased system weight and cost, and adverse effect caused to system reliability.Additionally, due in vacuum environment
Burning belong under pure oxygen state burning, generally more than 2000 degrees Celsius of temperature, the vacuum burner before designing adopts resistance to height
Warm coating or composite are to avoid damaging, but are the increase in system process complexity and cost.Integrated on vacuum burner
Pore throttling device simultaneously goes out in mixed gas and uses suitable material at air cover board, can effectively reduce use cost, weight and
Installing space, and improve burner reliability, tolerable temperature and working time.
Content of the invention
The technical problems to be solved in the utility model is to provide a kind of vacuum premix burner with pore throttling device.
The vacuum premix burner with pore throttling device of the present utility model includes throttling of fuel joint, fuel is led
Pipe, fuel give vent to anger sleeve, sealing base plate, oxygen throttle joint, compression plug screw, oxygen catheter, high temperature resistant go out air cover board, placket
Body, rear cylinder body and earthenware fixed block.
High temperature resistant go out air cover board be arranged in conveyor front barrel and the integrally welded groove of rear cylinder body, after sealing base plate is welded on
The cylinder other end, fuel conductor and oxygen catheter are welded on rear cylinder body, and fuel sleeve weld of giving vent to anger is stretching into inside rear cylinder body
Fuel conductor on, throttling of fuel joint and oxygen throttle joint are respectively welded on fuel conductor and oxygen catheter, in fuel
It is respectively provided with a compression plug screw, earthenware mounting blocks are welded on conveyor front barrel, and fuel passes through fuel on conduit and oxygen catheter
Throttle joint, fuel conductor and fuel give vent to anger sleeve enter rear cylinder body inner chamber, simultaneously oxygen pass through oxygen throttle joint and oxygen
Conduit enter rear cylinder body inner chamber mix with fuel, then from high temperature resistant go out air cover board gas outlet discharge and light.
It is integrated with throttling pore on described throttling of fuel joint and oxygen throttle joint.
Fuel is welded with described fuel conductor give vent to anger sleeve.
Described high temperature resistant go out air cover board adopt molybdenum alloy.
This utility model compared with prior art, has an advantageous effect in that：
Integrated pore throttling device eliminates special choke valve, reduce system cost, weight and improve work can
By property；In burning, temperature highest goes out and improves tolerable temperature and working time using molybdenum alloy at air cover board.
The vacuum premix burner with pore throttling device of the present utility model.Groove between conveyor front barrel and rear cylinder body
Install high temperature resistant go out air cover board after weld together, the rear cylinder body other end is welded with sealing base plate, oxygen catheter and fuel conductor
It is welded on rear cylinder body, fuel gives vent to anger sleeve weld on the fuel conductor stretching within rear cylinder body, oxygen throttle joint and combustion
Material throttle joint is respectively welded on oxygen catheter and fuel conductor, is respectively provided with a pressure on oxygen catheter with fuel conductor
Tight plug screw, earthenware mounting blocks are welded on conveyor front barrel.It is integrated with throttle orifice on oxygen throttle joint and throttling of fuel joint, save
Single choke valve, makes that whole combustion system space is less with quality, and cost is lower and reliability is higher；High temperature resistant give vent to anger
Cover plate improves the tolerable temperature of burner using molybdenum alloy, and the working time is longer.
