Description
Technical field
The utility model relates to fire row combustor fields.
Background technique
Fire row combustor is typically used in the heating such as module furnace, wall-hung boiler, water heater, steam generator, supplying hot water, for steaming
On the device of vapour, pedestal and several fiery pieces being disposed in parallel on pedestal, the spray that setting is aligned with fiery piece on pedestal are generally included
Mouth, nozzle spray combustion gas into the blast tube of fiery piece, in the process, by spraying injection principle, are able to drive surrounding
Air enters blast tube and combustion gas mixing, and mixed gas is discharged from the fire hole of fiery piece and is burnt later.
In recent years, since environmental issue is more and more severeer, most stringent of boiler is formally implemented on April 1st, 2017 in Beijing
Discharged nitrous oxides standard, it is desirable that the reduced value < 30mg/ that newly constructed boiler nitrogen oxide emission is 3.5% in benchmark oxygen content
m3While CO emission reduced value < 95mg/m3, subsequent multiple cities and area enact and enforce Beijing standard successively.
Main heating equipment of the burner as boiler, is the main source of boiler air pollution emission, selects more low NOx row
Burner high-volume is the main means for reducing boiler air pollution emission, energy saving to greatest extent and burner weight
Want performance indicator.
The discharge amount of nitrogen oxides and carbon monoxide depend on fuel gas buring it is abundant whether, combustion gas full combustion then can
Effectively reduce the discharge of nitrogen oxides and carbon monoxide.Traditional single injector fire row combustor is difficult to ensure the standard of oxygen and combustion gas
True mixed proportion occurs at present therefore, it is difficult to control the discharge amount of nitrogen oxides and carbon monoxide through high-accuracy electronics control
The all-premixing burner that system control combustion gas processed and air are premixed in full premix ratio, burning nature is abundant, and chemistry is endless
Full combustible loss is less, and the thermal efficiency is high, and nitrogen oxide emission can accomplish < 30mg/m3, carbon monoxide < 95mg/m3, discharge amount
Fully meet requirement.Although all-premixing burner can fully meet the air pollution emission of newly constructed boiler in terms of energy-saving and environmental protection
Standard, but to guarantee that the stability of full premix combustion controls it is necessary to carry out accurately ratio to combustion gas and air simultaneously, this is
The high nonlinear Control of difficulty.In combustion, the ratio control of combustion gas and air will definitely not occur all-premixing burner
Two kinds of situations: if premix air is insufficient, and there is no Means of Secondary Air Supplement, that is, anoxycausis, CO emission will
It can be substantially increased, here it is bad one of the reasons of full premix boiler energy-saving effects in actual use most of at present: such as
Fruit premix air is excessive, that is, crosses and premixes, when igniting is easy detonation.The steady flame problem of full premix combustion is another problem,
It is difficult to stablize flame using the fire hole structure that mechanical means is processed, almost global all-premixing burner is all using high temperature resistant
Metallic fiber establishment net package fire hole surface carry out steady flame, the method for this steady flame of micropore is very effective, but cost is very high,
And service life is short, is expensive vulnerable part, metallic fiber establishment net blocking in order to prevent influences burning, just must be tight to combustion gas
Lattice filtering and air-filtering processing, this not only adds the operating costs of boiler, and influence whether the stability of air-fuel ratio.Head
Portion's structure is more complicated and heavy to prevent tempering phenomenon, and it is complete pre- for having biggish noise all in high pressure, high load capacity
The shortcomings that mixed burner.
