摘要： PURPOSE:To enable efficient recovery by discharging the steam in a collecting duct after a peeled scale, water, steam are collectively collected in a collecting duct upward through a steam discharging duct and recovering a waste water containing a peeled scale from a recovery duct. CONSTITUTION:The flow of a waste water containing a peeled scale is collided with the jet flow injected from low pressure water injecting devices 12a, 12b, its flow is intercepted so as to fly away from the surface of steel and is taken in the hoods 13a, 13b of upper/lower parts. The steam generated in waste water proceeds as accompanying with the flow of waste to be taken in the hoods of upper/lower parts. The steam collected in the collecting ducts 14a, 14b of upper/lower parts through each hood is guided upward through steam discharging ducts 15a, 15b also the waste water collected in the collecting ducts of upper/lower parts is guided downward through recovery ducts 16a, 16b. In this way, the peeled scale, water, steam are efficiently recovered.

摘要： PURPOSE:To effect flow control without causing pressure loss in a centrifugal pump by installing a variable diffuser vane mechanism in the pump. CONSTITUTION:In a centrifugal pump B, a sensor 3, a positioner 5, actuator 4 and a variable diffuser vane mechanism 6 for changing the angle of a diffuser vane are installed. By adding the positioner 5 to the driving cylinder, it is possible to attain within the centrifugal pump B the same function as that of a conventional flow regulating valve to regulate flow rate in accordance with control signal 3a. Furthermore, pressure loss can be made nil. Thus, it is possible to save the shaft driving force in the pump.
