The principle of water supply for boiler blown door

The boiler blows the door to adjust the water level during operation. When the blow door is opened, the pressure drops rapidly, the water level rises rapidly, and the false water level is generated. At this time, the water supply should be increased. When the blow door is closed, the pressure rises first and then falls because of the pressure. Problem. The boiler blows the door to adjust the water level during operation. When the blow door is opened, the pressure drops rapidly, the water level rises rapidly, and the false water level is generated. At this time, the water supply should be increased. When the blow door is closed, the first rise and then fall is also Because of the pressure problem. However, after closing the door, the water should be properly reduced. Preventing large amounts of water, full of water. The water level fluctuation during blowing is quite large. The time of water level fluctuation depends on the length of the opening of the door. The principle is to increase the water supply when opening the door, and reduce the water when closing the door. To see the actual water level trend, the local water level gauge at this time does not reflect it. It will affect the normal safe operation. Http://?ID=377
