Does the fluidized air volume of the return device of the circulating fluidized bed boiler need to be adjusted at any time during operation?

　　The fluidizing air volume of the returner needs to be adjusted when it is started for the first time. Under normal circumstances, there is generally no need to adjust the air volume. During the operation adjustment period, in order to improve the operating conditions of the boiler, necessary adjustments can also be made to the fluidizing air and loose air of the returner.
