Apparatus And Method For Recovering Excess Gas Generated In Ironmaking Process
Abstract: Provided are an apparatus and method for stably recovering an excess gas generated in an ironmaking process. The excess gas recovery apparatus of the ironmaking process includes an excess gas recovery line, one or more gas storage unit, and a compressor. The excess gas recovery line is associated with at least one of a melter-gasifier-side excess gas line and a fluidized bed furnace-side excess gas line. The excess gas recovery line recovers/supplies the excess gas from/to at least one of the melter-gasifier, the fluidized bed furnace, and the reduction furnace. The gas storage unit is disposed in the excess gas recovery line and receives and stores the excess gas. The compressor is disposed in the excess gas recovery line of a downstream side of the gas storage unit. The compressor compresses the excess gas discharged from the gas storage unit. Therefore, a recovery rate of the excess gas can increase, a low-pressure small- capacity gas storage equipment can be used, and an operation control of equipments can be simplified.
