锅炉水动力试验主要是调整炉膛下辐射48片水冷壁进水量的分配,以适应炉膛热负荷的分布,使各片水冷壁在下辐射区出口工质干度基本一致,保障水冷壁的安全运行。先通过冷态调整,初步正定水冷壁进口48只节流调节阀的开度,在热态下再进行校核性试验。 Boiler hydrodynamic test mainly adjusts the distribution of water inflow of 48 water walls under the furnace chamber to adapt to the distribution of furnace heat load so that the dryness of the working medium at the lower radiation area of ​​each water cooling wall is basically the same so as to ensure the safe operation of the water wall. First through the cold adjustment, the initial positive water wall imports 48 throttle control valve opening, and then carried out in the hot state of the test.
