Name:coal burner
Introduction of coalburner:
Muti-channellow NOx discharge burner is designed and developed by our companybased on the technique requirement for lime or dolomite calcine andthe characteristic of temperature distribution in rotary kiln aswell as the mechanism of NOx forming in the process of combustionof fuel.
Purpose:as the source of heat for rotary kiln, to meet the requirement ofsystem quantity of heat.
Principle:by means of muti-channel burning technique, the first air and fuelis divided into different flow, and based on the whirlwind spinningeffect, to speed up the mixing of fuel with first air. Aftermixing, the rapid shooting flow is formed, meanwhile again, bymeans of different speed of flow occurs interface attritionfunction, to make the rapid flow absorb the slow flow, that iswhirl absorb the second high temperature air. Therefore to speed upthe fuel speed of heat and reaction speed of fuel. Using thekinetic energy of rapid current shooting flow to absorb all thesecond air, to make them take place at good physics mixingcondition and burning chemical reaction states.
Characteristic ofcoal burner
1,based on themechanism of forming NOx (forming NOx mechanism and fuel NOxmechanism) during the course of burning of fuel to form NOx, tocontrol the NOx content in fume.
2,Muti-channel low NOxdischarge burner can make the NOx consistence in fume greatlydecrease, 40-60% lower than normal, by applying feedback result toindicate that the NOx content in fume at end of kiln normally is350~400ppm, about 50% lower than ordinary value 800ppm which havereached the advance level in international.
3,Muti-channel low NOxdischarge burner is fixed on the moving device which are designedespecially for the burner. Applying universal model design canensure this burner regulate agility within the degree of 3° atdirection of up-down and right-left. Meanwhile, also to ensure itcan be moved forward and backward over the distance of 700mm,therefore to easy regulate length of flame as well as burneroverhaul.
4,the shape and lengthof flame for Muti-channel low NOx discharge burner can meet therequirement for calcining technics and temperature distribution inrotary kiln, and the shape and length of flame can beadjusted.
5,the temperature offlame can be controlled, that is the top temperature can becontrolled, therefore to prevent the material over-burning, to makethe kiln avoid forming ring block.
6,muti-phase burningand mixing burning can be adapted, also can be used sole burning insingle-phase fuel.
