摘要:
A feedback pipe is connected to the outlet and inlet sides of a storage blower directing unburned gas from an oxygen blast converter to a storage tank. Alternatively, the unburned gas is discharged to the atmosphere. Control valves moving in contrary directions are coupled to a single controller for maintaining the pressure in the storage delivery pipe constant regardless of whether unburned gas is discharged to the atmosphere or directed to the storage tank.
