How to control the ventilation rate of the rotary furnace? I believe many friends do not know. Silicon carbon negative electrode coating equipment and you will take a look at how to control the ventilation rate. Under normal circumstances, when the air volume of the rotary furnace is small, the oxygen supply is insufficient, the combustion speed slows down, and the heat consumption increases. When the ventilation rate is large, the gas flow rate increases, the combustion decomposition time shortens, and the smoke volume after combustion is large, resulting in high heat consumption. This will affect the normal operation of the kiln. Therefore The ventilation rate of the rotary kiln should be controlled. As ventilation is low, oxygen supply is insufficient, combustion speed slows down, and heat consumption increases; When the ventilation volume is high, the gas flow rate becomes faster, the combustion decomposition time becomes shorter, and the amount of flue gas after combustion is large, resulting in high heat consumption and affecting the normal operation of the rotary furnace
However, there are also some factors that can affect the ventilation volume, such as changes in resistance throughout the system, air temperature, whether the system is leaking air, whether cold air is mixed in at the fan inlet, and whether there is cold air present. Is there any interference between the kiln systems due to dust accumulation, blockage, or even material distribution in the pipeline. These factors can all affect the ventilation of the rotary furnace, so it is necessary to adjust and control the ventilation in a timely manner. In production, to control the ventilation rate of the rotary furnace, it is necessary to accurately measure the ventilation rate. The measurement method can be determined by observing the negative pressure at the ventilation inlet of a device. Only by accurately measuring the ventilation volume and controlling the ventilation volume of the kiln can the working capacity of the rotary kiln be maximized
In response to the above influencing factors, the ventilation volume should be adjusted and controlled. When the air temperature of the rotary furnace changes, it needs to be controlled within this range, so different measures should be taken according to different situations. So much for today's silicon carbon negative electrode coating equipment
