What are the Advantages of a Four Channel Pulverized Coal Burner
1. The appearance and characteristics of the flame are good:
The four-channel magnesium pulverized coal burner has a variety of adjustment methods, with different proportions of internal and external air and inlet and outlet jet flow patterns that can be adjusted in a wide range without changing the total air cooling standard, thus obtaining a flame appearance that can integrate into all working conditions
2. Energy conservation and emission reduction: Due to the low primary exhaust air volume and the adjustable proportion of direct current and vortex air, it is beneficial for the ignition of coal powder. Therefore, the four-channel coal powder burner can reasonably reduce coal consumption. Basic theory and practical activities have shown that every 1% reduction in primary exhaust air volume can reduce heat consumption by 8.70 to 10.46kJ/kg of fuel. In addition, the secondary air temperature has significantly increased.
3. Strong adaptability to coal, which can be used as low volatile coal or anthracite; According to the water content (%) of volatile matter ignited, the particle size of pulverized coal is adjusted appropriately (generally the 0.080mm sieve residue percentage is controlled at 0.5~0.75 times of the volatile matter percentage). In addition, the low volatile coal or anthracite can be used for burning in the cement rotary kiln relative to the investment attraction of the combustion machine.
4. Low NOx consumption: When everything is working normally, there is high-temperature smoke and dust flowing back to the air pressure zone at the top of the four-channel pulverized coal burner head, which can prevent partial high temperature. The temperature curve along the kiln length changes stably, so the production of “ignited NOx” and “high-temperature NOx” can be reasonably suppressed, with a reduction of 20-30%. The smoke and dust discharge meets the national environmental protection standards.
5. Reasonable configuration and overall good characteristics: The four-channel coal powder burner has a beautiful and elegant appearance, complete service facilities, low system software friction resistance, flexible and convenient flame adjustment, convenient maintenance, and overall characteristics that exceed the level of overseas multi-channel combustion machines.
6. Technical application and material guarantee service life: The vulnerable positions of the four-channel coal powder burner have been equipped with wear-resistant paint technology, which has increased the wear-resistant service life of the combustion machine by 5-10 times compared to ordinary steel. The head and nozzle of the four-channel coal powder burner are made of heat-resistant steel material, which can ensure that the combustion machine has a service life of about 2 years at the standard of 1100 ℃.
7. Accurate positioning adjustment is convenient and flexible:
The suspension equipment of the four-channel coal powder burner must be retractable and offset according to the working conditions inside the kiln, adjusting its position in the kiln to ensure stable and reliable insulation regulations. The inner and outer waterproof sleeves of the vortex flow safety channel are all of the radial retractable construction, and the visual working conditions must be adjusted immediately to make the nozzle expand and expand the actual effect
