High Hydrogen fuel Flat-flame ultra-low NOx emission oil and gas combination burner
Technical field
The present invention relates to a kind of petrochemical industry burner apparatus, in particular to a kind of high ultralow NOx of Hydrogen fuel Flat-flame
Discharge oil and gas combination burner.
Background technique
There is most Furnace at present, since, at a distance of relatively closely, burner flame shape is set between boiler tube and boiler tube
It counts unreasonable, just will appear flame and lick boiler tube, lead to the non-uniform temperature on boiler tube, it is serious that local overheating region is easy coking,
Greatly shorten time between overhauls(TBO) and boiler tube service life.
Last century the nineties are entered, with the needs of energy conservation and environmental protection, most oil refining, chemical industry, chemical fertilizer factory are all right
The recycling of the self-produced gases such as the self-produced dehydrogenated tail gas of each device (containing Gao Qing), resolution gas, desorption gas, is no longer sent to torch
Burning.Since these refinery gas have the features such as hydrogen content is high, calorific value is relatively low, and gas quantity and component change with oil quality, because
This will integrate these factors in the design of burner, and according to environment protection emission NOx requirement up to standard, realizing ultralow NOx at present
Burning, present manufactory is general lack of such solution and for reaching the burner product of ideal effect.
" petroleum refining industry pollutant emission standard " (GB 31570-2015) regulation of State Environmental Protection Administration's publication
2015-07-01 comes into effect, and one type area NOx emission requires to be lower than 100mg/m3.Domestic petroleum chemical heating furnace burner
Low NOx drainage combustion technology can only mostly guarantee that NOx emission reaches 50PPM or so (80 ~ 120 mg/m3), and foreign countries is similar
Burner product is discharged up to 20 ~ 30PPM.On the burner using a variety of technological means for inhibiting NOx, such as: fuel staging combustion
Burning, bias combustion, fuel fires again, flue gas recirculation etc., still, the advanced effect of external similar product is not achieved always.
There are some places interfered with each other in structure application, when practical application, cannot be adjusted numerous technologies according to operating condition again
Whole, therefore, some products there is that flame rigidity is bad, and flame drifting burns phenomena such as insufficient, NOx emission index also pole
