Abstract
The utility model relates to an anti-radiation burner which is used in high power high temperature heating and heat treating furnaces. An air inlet is arranged on a burner shell, the inner end of the burner shell is connected with a ceramic swirl plate and a burner brick, a coal gas inlet pipe is arranged on the outer end of the burner shell, a coal gas inlet is connected with a central coal gas burner cap through a connection pipe, the ceramic swirl plate is arranged on the end portion of the central coal gas burner cap, and an ignition burner is arranged in the middle portion of the burner. A flame monitor is arranged on the outer end of the burner shell. Pressure testing connectors are installed on the coal gas inlet and the air inlet. The coal gas inlet, the burner shell, the ceramic swirl plate and the burner brick can be respectively and independently assembled and disassembled. An ignition electrode is threaded through the burner shell and the ceramic swirl plate from the coal gas inlet and can reach near the central coal gas burner cap of the burner. A high temperature-resistant ceramic prefabricated cyclone structure is adopted to bear heat radiation of more than 1100DEG C under the condition without cooling, air cooling is not needed when the burner stops working under the high temperature condition, the anti-radiation burner has the effects that the energy sources can be saved, Nox discharge can be lowered, and anti-radiation burner materials can be saved. Simultaneously, the anti-radiation burner has rational structure, convenient maintenance and easy replacement.
Description
Technical field
The utility model belongs to gas burner, particularly a kind of high power high-temperature heating and heat-treatment furnace radioresistance burner.
Background technology
For various operating temperatures at the high-temperature heater more than 1100 ℃, intermittently used cell-type especially, the car-type high-temperature heater, often technological requirement stove frequent fire door of opening under the condition of high temperature takes on material, require heating system to quit work this moment.Burner must bear the heat radiation more than 1100 ℃ under the situation that does not have cooling. and use the ordinary combustion device,, at high temperature work long hours and cause the distortion of burner internal structure easily, even damage because of its air ejection-eddy flow adopts metal structure.In the practice, damage because of hyperthermia radiation, often require bubbling air cool burner under burner quits work state, cause thus that to be heated the workpiece oxidization burning loss serious, produce bigger thermal loss simultaneously, waste energy in order to prevent burner.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of high power high-temperature heating and heat-treatment furnace radioresistance burner are provided.High-temperature heater is in hot operation, and heating system temporarily quits work.Burner can bear the heat radiation more than 1100 ℃. and the burner internal structure is indeformable, does not damage.
The technical solution of the utility model is:
A kind of high power high-temperature heating and heat-treatment furnace radioresistance burner, it is characterized in that: on the burner shell, air intake is arranged, burner shell right-hand member connects ceramic spinning disk and burner block, burner shell left end has the gas entry pipe, gas entry is connected to the center gas-jet by adapter, periphery is with ceramic spinning disk in gas-jet end, center, is provided with igniter burner at the burner middle part.
On burner shell left end, flame monitor is arranged, pressure measuring tie-in is housed at gas entry and air intake.
Burner is made up of gas entry, burner shell, ceramic spinning disk and the burner block that can distinguish independent dismounting.
Ignitor passes burner shell, ceramic spinning disk from gas entry, and the center gas-jet of arrival burner is neighbouring, burner shell inwall has insulation material.
The utility model characteristics and effect are:
Heating/the heat treatment of the utility model high temperature adopts the prefabricated cyclone structure of refractory ceramics in the heat radiation that does not have can bear under the situation about cooling off more than 1100 ℃ with the radioresistance burner, does not need the air cooling when burner quits work under hot environment.And have the saving energy, reduce the Nox discharging, the effect of saving heat-resisting allay material.Nozzle structure is reasonable simultaneously, maintains easily, changes.
1, this burner sky/coal gas mixed vent adopts the refractory ceramics body structure, and air (cold wind or hot blast) is from this particular design and have the ceramic body ejection of certain angle eddy flow hole, mixes, burns with coal gas from the central nozzle ejection.This ceramic body is prefabricated sintering structure, can be porous direct current pattern or porous eddy flow form, according to the variation of ceramic body project organization, the combustion air of ejection can burn with the coal gas mixed once, also can carry out secondary or multistage mixed combustion, reduce Nox discharging purpose to reach.
2, for the hot blast burning, INSULATION DESIGN in this burner adopts, thus reduce the burner housing temperature, improve operating environment, reduce thermal loss.
3, this burner is provided with electronic ignition electrode or igniter burner installation site, and flame detecting and flow detector are convenient to combustion position is measured control; Ignitor can be extracted out at any time and be screwed into, convenient maintenance.
4, this burner is provided with two-way coal gas feed path, is convenient to implement " big fire-little fire " control burning;
5, burner adopts the segmented modular structure, the convenient installation and maintenance.Burner is divided into three sections: gas entry, burner shell, ceramic spinning disk-burner block are formed, and can dismantle arbitrarily, change for three sections.
6, according to the difference of the outlet geomery of burner block, can obtain different spouting velocities, satisfy the kinds of processes needs.
Description of drawings
Fig. 1 is the structural representation that high power high-temperature heating and heat-treatment furnace are used the radioresistance burner
The specific embodiment
As shown in Figure 1 a kind of high power high-temperature heating and heat-treatment furnace radioresistance burner, air intake 2 is arranged on burner shell 1, burner shell right-hand member connects ceramic spinning disk 3 and burner block 4, burner shell left end has gas entry pipe 5, gas entry is connected to center gas-jet 6 by adapter, periphery is with ceramic spinning disk 3 in gas-jet end, center, is provided with igniter burner 8 at the burner middle part.
On burner shell left end, flame monitor 9 is arranged, pressure measuring tie-in 10 is housed at gas entry and air intake.Burner is made up of gas entry, burner shell, ceramic spinning disk and the burner block that can distinguish independent dismounting.Ignitor 11 passes burner shell, ceramic spinning disk from gas entry, and the center gas-jet of arrival burner is neighbouring, burner shell inwall has insulation material 7.
