Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic diagram.
Detailed description of the invention
This device comprises bellows 1, igniter 4, flame inspection section 2, flame monitor 3, terminal box 5, as shown in Figure 1, described bellows 1 are provided with low fiery fuel gas inlet, and low fiery fuel gas inlet connects low fiery gas nozzle 8, and the outside of low fiery gas nozzle 8 is provided with First air cyclone 10; Described bellows 1 are provided with high fiery fuel gas inlet, and high fiery fuel gas inlet connects high fiery gas nozzle 11, and the outside of high fiery gas nozzle 11 is provided with Secondary Air cyclone 12; Described low fiery gas nozzle 8, high fiery gas nozzle 11 are concentric structure, and low fiery gas nozzle 8 connects a combustion air, high fiery gas nozzle 11 connecting secondary combustion air.
The fiery gas nozzle 11 of described height and Secondary Air cyclone 12 arranged concentric, form premixing space between the two, high fiery gas nozzle 11 exports and secondary combustion-supporting wind passage angle in 90 °.
Described low fiery gas nozzle 8 downstream is provided with low fiery bluff body flame holder 9.
Described low fiery fuel gas inlet is provided with low fiery stop valve 6; The fiery fuel gas inlet of described height is provided with high fiery stop valve 8.
Embodiment
Low fiery combustion gas is carried out eddy diffusion with a combustion air of high speed, high pressure and is mixed after low fiery gas jet orifice ejection, realizes quick, smooth combustion, form low fiery flame after igniter is lighted.According to Load Regulation needs, high fiery combustion gas sprays into secondary combustion-supporting wind air duct from the fiery gas jet orifice of height with the speed of 90 ° of angles, (30 ~ 70) m/s thus makes combustion gas and air pre-mixing for gas-air mixture, from the ejection of ring-type spout, after low fiery flame ignition, form high flame.Low fiery bluff body flame holder makes high-temperature flue gas fully reflux, and ensure that the reliability and stability that low fiery combustion gas is caught fire, and avoids de-fiery state and produces.
Combustor is provided with two cover gas nozzles, and a set of is low fiery gas nozzle, and a set of is high fiery gas nozzle, and two cover gas nozzles are concentric structure, and blast tube is separate.When burner runs under low fire, only open low fiery combustion gas; When low fire runs above, low fire and the combustion gas of height fire are all opened.
First air cyclone and Secondary Air cyclone is provided with respectively in the outside of low fiery gas nozzle and height fire gas nozzle.
High fiery gas nozzle body and Secondary Air cyclone arranged concentric, form certain premixing space between the two.Gas jet orifice outlet and secondary air channel angle in 90 °.
Low fiery bluff body flame holder is provided with in low fiery gas nozzle downstream.
1 burner structure
Architectural feature:
A) concentric structure is adopted to be provided with the separate low fiery gas nozzle of passage and height fire gas nozzle;
B) outside low fire, high fiery gas nozzle, combustion air, a secondary combustion-supporting wind cyclone is provided with respectively;
C) combustion gas, air pre-mixing space is defined between high fiery gas nozzle body and Secondary Air cyclone;
D) a low fiery bluff body flame holder is provided with in low fiery gas nozzle downstream;
2 operation principles
After combustor moves to ignition flame foundation, low fiery combustion gas sprays into primary air from low fiery gas nozzle carries out eddy diffusion mixing, is lighted the low flame of rear formation, and gas jet orifice outlet is 90 ° with empty air flow direction angle; When after the high fiery gas consumption adjusting valve of Load Regulation signal input, high fiery combustion gas from the ejection of height fiery gas jet orifice, and with the change of Load Regulation signal adjustment of combustion gas flow.Combustion gas sprays into secondary combustion-supporting air with the speed of 90 ° of angles, (30 ~ 70) m/s, and its kinetic transformation is diffusion mixing potential energy, makes that combustion gas and air are quick, Homogeneous phase mixing, rapid ignition.In combustion, low fiery bluff body flame holder ensures that high-temperature flue gas fully refluxes, and ensure that the reliability and stability that combustion gas is caught fire, and avoids de-fiery state and produces; Before catching fire, combustion gas and air are entered by autonomous channel and revolve mouth, do not allow mutually to mix, and avoid Annealed Strip and produce.
