Abstract
Gasification equipment with a gasification furnace which maintains a. high cold gas efficiency, and suppresses a temperature rise of the gasification gas to minimize ash deposition is disclosed. A part of a CO2 gas separated from an exhaust of a power generation plant is compressed by a. recovered CO2 compressor 25. The compressed CO2 gas is used for transport of coal (pulverized coal). The CO2 gas is supplied, together with the pulverized coal, into a gasification furnace to accelerate the formation of CO by an endothermic reaction between C and CO2 and suppress a temperature raise within a coal gasification furnace 15, thereby producing a gasification gas.
