Introduction To Rotary Kiln Burners
The multi-channel mixed gas burner is developed by Silver Flame Machinery to adapt to the actual situation where the calorific value of combustible waste gas in industries such as steel and chemical industry is too low and a single gas cannot meet the needs of rotary kiln technology. Developed using independent technology, a multi-channel mixed gas burner suitable for combustible gases such as blast furnace gas, converter gas, coke oven gas, calcium carbide furnace gas, electric furnace gas, submerged arc furnace gas, and generator gas. The burner has high combustion efficiency, lively and powerful flames, and is less affected by changes in gas pressure. The structure is easy to maintain.
1. Utilizing the low calorific value waste gas generated in the production process of steel and chemical industries, improving resource utilization, reducing energy consumption, and reducing pollution emissions.
2. Using CFX simulation technology, calculate the relevant parameters of the end flow field, design a reasonable combustion air and fuel channel structure, form a regular and complete flame shape, adjust flexibly, stabilize the flame without fluctuations, do not sweep the kiln lining, and the temperature distribution meets the process requirements.
3. By optimizing the configuration of combustion supporting axial and swirl air, the kinetic energy of the external axial flow air is increased, and the high-temperature secondary air entering the kiln is fully utilized to reduce the proportion of primary air and energy consumption.
4. The use of a multi porous radiative distribution structure improves the airflow and temperature field of the flame core, improves the flame shape, increases fuel burnout rate, and reduces CO and NOx emissions.
5. The burner channel adopts a new drag reduction structure and process to reduce the impact of gas pressure fluctuations on flame shape.
6. The nozzle material is made of a product that can withstand temperatures ranging from 1350 ° C to 1400 ° C, is wear-resistant, and has a long service life.
