Rotary Kiln Burner

The rotary kiln burner is a kind of special engineered burner for nonferrous metallurgy, chemical industry, cement, steel industry etc. At present, according to customer’s situation, this series of burner adopts different flame length and diamter, adopting multichannel structure. The fuel of rotary kiln burner could be coal powder, gas, heavy oil, light oil, coke oven gas, converter gas, etc. According to the working condition, the rotary kiln burner could use multiple fuel.

HD Rotary Kiln Burner could deal with the difficult challenge of different rotary kiln type, different pulverized coal character and different process conditions, which assure the intensive mixing of pulverized coal, primary air and secondary air, high combustion efficiency, high thrust, big speed difference coal and wind blending, supersonic wind speed, the flame in high strength, good rigidity, Strong stability. Now HD Rotary Kiln Burner has possessed a number of independent patent technology property rights, and successfully repeated verification and adopted by several important cement plant.

HD Rotary Kiln Burner is developed and manufactured on the basis of two years collecting the statistical data of the clinker firing system of 300 cement plants, summarizing and analyzing of technology advantages and disadvantages of domestic and foreign advanced pulverized coal burner, adopting the latest combustion technologies theory of large velocity difference and strong Vortex Flow, applying largecomputer simulation technology and CFD(Computational Fluid Dynamics) numerical simulation technology. The performance is up to international advanced level in the field of pulverized coal rotary kiln burner. HD Multichannel Intelligent Vortex Flow Burner is mainly used for the field of cement rotary kiln -- firstly brings military technology to civilian technology; firstly adopt CFD numerical simulation, Fibonacci spiral vortex and stepless regulation; firstly introduce HJ additives for diamond tools to thermal spray techniques.The normal service life of the whole machine is up to 2 years, which has been widely appreciated by the industry.

●Supersonic wind speed, mixture of air and coal with high thrust and large velocity difference.

The external axial wind speed higher than 1.1 Mach; Pulverized coal wind speed 25--30m/s, the mixture of air and pulverized coal mix very well, the burn-off rate of pulverized coal can reach more than 99%. 

●  The flame shape could be stepless adjustment, suitable for different kilns.

Except the coal powder wind channel, other 3 wind channels could be adjusted at any time to suit for All kinds of complicated work environment.

● Good flame shape, powerful flame, good stiffness, no peak temperature.

The whole firing zone has strong and even thermal radiation, which is helpful to the growth of clinker agglomeration and mineral crystal phase, no hurting the kiln crust, with excellent maintainability of refractory brick.

●  Environmental friendly, low nitrogen oxide emission.

Because of the greatly largely decreasing usage of primary air, at the same time, on the function of the external axial flow and Vortex Flow wind, avoiding peak temperature;significantly decreases NOx emission by 20-35% compared with traditional low momentum pulverized coal burner.

● Low primary air volume, obvious energy-saving effect.

Coal saving:the primary wind is 4%-5%, the flexible adjustment of external axial flow and Vortex Flow wind, high combustion efficiency. Compared with traditional rotary kiln burner, coal saving is up to 5-15%.

Electricity saving:the installed capacity of the wind distribution skill of combustion system is greatly decreased, compared with traditional rotary kiln burner, electricity saving is up to 15-35%.

●  Wear proof and anti corrosion, long service life.

The head of the burner adopts HJ additives for diamond tools combined with thermal spray techniques, it has better corrosion proof and abrasion proof performance, with antioxidant above 1200℃. The normal service life can be up to 1 year under full load, and the whole machine is up to 2 years.
