The actor defect of low nitrogen burner introduces

One, interest:
1, as a result of drawing combustion area, weakened partial combustion intensity, inside proper time, restrained of NOx form.
2, combustion of small negative charge is smooth. Because reduced bottom wind force, when making fuel burns in low density, very smooth also. Can accomplish 40% bear to stabilize combustion even.
3, when small negative charge, it is better that circumfuse of blaze of the chamber of a stove or furnace is spent. Water-cooling wall absorption of heat is even.
2, defect:
1, because light wind position, make a lot of sending wind is in break away from the chamber of a stove or furnace to did not attend combustion, and this part sirocco also is from empty beforehand implement absorbed a lot of caloric, can form smoke evacuation temperature to cross low phenomenon consequently. It is especially when small negative charge.
2, enter wind force as a result of what weakened bottom the chamber of a stove or furnace, make issue wind 2 times hold in the palm help ability up to weaken, cuttings pick-up quantity is added, cuttings pick-up contains carbolic quantity to add, especially when high load capacity.
3, take wind as a result of what weakened bottom the chamber of a stove or furnace, make the tigidity of wind is weakened, combustion area is patulous, when high load capacity, brief present water-cooling wall the knot is anxious.
4, because bottom of the chamber of a stove or furnace is anoxic,burn, fit a lot of recovering from an illness sexual gas, make grey melting point drops, form cold broken bits to fight even have the appearance with anxious knot.
5, the drawing as a result of combustion area, in period of high load capacity, can form superheater overheating, decrease Wen Shui to measure insufficient phenomenon, austere when, form screen to cross a knot even anxious.
6, because a lot of recovering from an illness of sexual gas and combustion area patulous, make knot of the bottom in water-cooling wall anxious austere, because take off anxious the bring back to life that make, deflagrate, attaint scoops up phenomenon of broken bits machine to have show effect.
7, because the knot when high load capacity is anxious,affected water-cooling wall absorption of heat, make temperature of bottom of the chamber of a stove or furnace rises, and because the position can is opposite only,light wind the flue gas of upside of the chamber of a stove or furnace undertakes cooling, and be without an influence to temperature of bottom the chamber of a stove or furnace, consequently the fit of NOx of bottom of the chamber of a stove or furnace writtens guarantee accordingly anxious and add, high load capacity continues time is longer, the effect that reduces NOx is less, exceed original NOx amount even.
8, cent of rising of combustion of bottom of the chamber of a stove or furnace, upside lights the theory that burns coke, with coal fines portion of combustion " rising divides ash content of watchcase of → of combustion of coke of → of combustion of portion of rising giving → to come off, the theory that rising divides those who follow watchcase ash content to come off ceaseless cent gives " not conform to. Consequently, when high load capacity, the combustion time of a lot of coal fines spins, coal fines of not complete flaming is taken flue. Form flying ash to contain carbolic quantity to increase.
