| When the outlet flow of the pre-pump is less than 148t/h, the feedwater pump recirculation door should be opened to prevent the feedwater flow from being too low and causing cavitation of the feedwater pump. When the feedwater flow is greater than 325t/h, the feedwater pump recirculation door should be closed to ensure normal water supply to the boiler. |
