In the roasting operation of chemical rotary kiln, the operator can flexibly adjust the flame according to the calcination needs, such as coal feed, internal and external net air volume and wind speed can be flexibly adjusted to meet the needs of kiln conditions The relevant content of the adaptability is as follows:
1. Operate through the handle during adjustment, instruct the instrument and device to monitor, and the adjustment operation is flexible, simple, convenient and wide in scope. There is also a problem that is easily overlooked, that is, the rotary kiln system must have strong adaptability to fuel, so that the fuel can be fully utilized and the yield can be improved;
2. The chemical rotary kiln has strong adaptability to fuel, which is beneficial to the use of low-volatile and low-activity fuels. The combustible components of coal are mainly volatiles and fixed carbon. Inferior coal anthracite with low volatiles has a lower ignition temperature than ordinary bituminous coal. Much higher
3. When using low-volatile bituminous coal, anthracite coal and high-ash inferior bituminous coal for calcining clinker in chemical rotary kiln, in addition to controlling the fineness of coal powder, the most important thing is to have a suitable coal powder burner to strengthen the ignition of coal powder combustion;
4. The new multi-channel pulverized coal burner adopts hot flue gas recirculation technology, that is, a 200m / s even supersonic external wind and coal wind and internal wind form a large speed difference, which causes a negative pressure recirculation zone in the burner outlet area. The high-temperature flue gas and high-temperature secondary air that have been ignited are sucked into the burner nozzle and mixed with the low-temperature primary air and coal, so that the unfired pulverized coal gas flow mixture is quickly heated, and volatiles are precipitated and quickly ignited.
