摘要: A system for controlling the pressure of the gas generated from a converter in noncombustion state and collected in a hood with atmospheric air being excluded from the hood including cooling and dust removing means for the gas before the gas is stored. The pressure of the gas within the hood is detected as one signal factor, said detected signal factor being applied to an adjusting instrument so as to actuate a mechanism in said system for controlling the pressure of the gas by opening and closing a damper located in a duct leading from the hood. The system further includes a mechanism for delaying the time the damper in said duct is opened or closed by applying a signal factor other than said signal factor derived from the pressure of the gas in said hood to said adjusting instrument.

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.
