True or False: In a circulating fluidized bed boiler, a combustion mode in which the static pressure of the flue gas at the furnace outlet is lower than the external atmospheric pressure is called negative-pressure combustion. （）
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (√)
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (Incorrect)
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (X)
Error. Positive and negative pressures should be distinguished by the pressure in the boiler combustion chamber~~
Error: Negative pressure combustion should mean that the pressure in the combustion chamber is lower than atmospheric pressure.
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (Correct)
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (×)
For circulating fluidized bed boilers, a combustion mode in which the static pressure of the flue gas at the furnace exit is lower than the external atmospheric pressure is called negative-pressure combustion. (Mistake)
