摘要 |
A washer having a controlled-gap scrubber is connected to the gas outlet of a pressure blast furnace and an expansion turbine for the recovery of energy is connected downstream of the controlled-gap washer unit while a bypass is connected across the turbine. The system has operating regions A and B on a diagram in which the gas pressure is plotted along the ordinate and the volume rate of flow of gas from said blast furnace is plotted along the abscissa, the region A being defined between the turbine-insertion and the turbine-operating characteristic curves plotted on the diagram, the region B being defined between the turbine-operating characteristic curve and the corrected blast-furnace characteristic curve. The pressure in the blast furnace where the operating point is in region A while the gas traverses the turbine is controlled by varying the gap width of said control-gap washer unit in response to the pressure. The pressure in said blast furnace when the operating point is in the region B is controlled by varying the cross-section of the bypass valve, the gap of the washer being controlled in response to the differential pressure thereacross. |
