The four-channel pulverized coal burner is a new kind of lighting equipment which is developing in the international market.It is superior to the three-channel safe pulverized coal burner that China has been constantly marketing and promoting, and far superior to the multi-channel burner, an outdated machine and equipment.SR series products introduced by our company with excellent technology are more suitable for all kinds of cement rotary kilns and waste heat boilers.
The pulverized coal is ejected outwards from the coal ventilation duct through the cyclone belt at a certain Angle of external diffusion, and is sent to very high angular momentum and moment by the adjacent swirling wind, spiraling forward at high speed, and then diffuses axial outward again to meet the high-speed-out axial flow wind beam.The insertion of axial flow wind beam further enhances the mixing of coal and wind (including secondary air around), and can adjust the emission level of fire. It can adjust the length and size of fire according to the need to exceed the need of fire appearance.The role of the management center wind is to promote the management center part of the small amount of fine coal and CO ignition, so that the ignition more sufficient, and play the effect of steady flow.Due to the principle of ignition and the high speed of swirling and axial winds, ignition is very fast and thorough.
The appearance of the flame is more standard and detailed: to overcome the irregular appearance of some three-safe passage burners and the defects of sweeping the kiln skin, so as to increase the service life of the kiln lining;
Environmental protection and energy saving: it can reduce the volume of primary air exhaust from 20~ 25% of multiple channels and 12.5~ 15% of three safe channels to 7~ 10% and at least 4%.In addition, the relative improvement of secondary air speeds up the heat exchanger in the cooling machine and improves the heat utilization ratio of cement clinker.And the sufficient ignition of coal to exceed the goal of saving resources;Compared with the multi-channel, the coal saving is about 10%, and the coal saving is about 3%.
Can ignite low value easy coal, fake and inferior coal, anthracite, reduce cost cost;
Improve the quality and production capacity of cement clinker: because of the improvement of secondary air, cement clinker can be refrigerated more adequately and rapidly, thus improving the quality of cement clinker;Because of the high efficiency of ignition and cement clinker refrigeration speed to increase kiln production;
Reduce the water content of CO and NOX: Because the coal wind mixing is more sufficient and the ignition is more rapid and thorough, the water content of CO and NOX in the organic waste gas at the kiln end is reduced, which is beneficial to the safe operation of electric dust removal and environmental protection.
Free online adjustment is convenient: according to different coal quality and processing technology regulations, the length, size and height of the fire can be arbitrarily adjusted, and the scope of adjustment is large;
Long service life: the nozzle is made of material, which can resist oxidation at 1200℃;The wear-resisting ceramic protective layer at the entrance of pulverized coal can avoid the erosion of pulverized coal on the burner.
