Utility model purpose of the present utility model can adopt following technical scheme to realize:
The flat flame burner of a kind of hydrogen manufacturing conversion furnace tipburn high-temperature preheated air has the flat flame high and low pressure gas gun of coaxial setting, and flat flame high and low pressure gas gun is positioned at burner upper shell center; The shower nozzle of described flat flame high and low pressure gas gun is arranged in the internal chamber of brazier brick; The place has a negative pressuren zone at the low pressure gun head; Described flat flame burner has aeration structure three times, three aeration structures have wind air duct, secondary wind air duct (10), tertiary air ventilating opening (7) respectively, a described wind air duct (5) is arranged on the top of brazier brick, a wind passage (9) of wind air duct (5) one end and burner shell one side, an end is communicated with the brazier brick internal chamber; Described secondary wind air duct (10) is communicated with quirk brick burning gallery with circular passage between the burner shell by brazier brick and brazier brick; Described tertiary air ventilating opening (7) is arranged on the brazier brick and with the brazier brick internal chamber and is communicated with, and tertiary air is by having the circular passage between quirk brick and the brazier brick.
Described high-low pressure gas gun is dismounting type separately.
Owing to adopt above-mentioned technical scheme, the utlity model has following superiority:
1, two gas guns of high-low pressure have been adopted, if low pressure gas pressure＜0.015mpa, not enough for preventing to spray energy, adopt the high pressure gas ejection structure, when the low pressure gas hypotony, combustion flame is easily unstable, causes flame to lick boiler tube, adopt high pressure gas to replenish injection, can improve flame rigidity.Avoiding flame to lick the boiler tube phenomenon takes place.
2, adopt " air classification mixes for three times " mode, direct current wind flows to wind facies and combines with interting, and the inclined hole on brazier brick is introduced air, forms root direct current wind and interspersedly flows to the air distribution technology that wind facies combines.
3, combustion process is that chemical energy is transformed into heat energy, high-temperature flue gas has interior energy, and capacity for work can be arranged, and high-temperature flue gas ejiction opening speed designs is up to 60m/s, this speed makes the burner inlet place draw into certain negative pressure, and this negative pressure helps the ejector action of low-pressure fuel gas greatly; The high temperature and high speed flue gas has strong mechanical disturbance simultaneously, not only helps the convection heat transfer' heat-transfer by convection of radiation chamber, and plays the backflow effect of flue gas, makes radiation chamber cross section temperature be tending towards even.
4, the flat flame burner of hydrogen manufacturing conversion furnace tipburn high-temperature preheated air adopts the preheated air of temperature above 450 ℃ as combustion air, adopts unique internal mix structure, reinforced high pressure liquid amount diffusion strength aroused in interest; Adopt multi-stage angle-variable formula blowing system, combustion gas flame and combustion air are formed have certain thermodynamic cycle flow field; Make a large amount of PSA low pressure gas that (0.002～0.02Mpa) can directly be used as fuel, also makes the NOx growing amount be better than the advanced discharge standard in the world.
