    Coal Gasification Boiler (IGCC) | go2alam

    Coal and/or petroleum coke is pulverized and fed into the gasifier along with oxygen that is produced in an on site air separation unit. The combination of heat, pressure, and steam breaks down the feedstock and creates chemical reactions that produce hydrogen .


    Three major types of gasification systems are used today: moving bed; fluidized bed; and entrained flow. Pressurized gasification is preferred to avoid large auxiliary power losses for compression of the syngas. Most gasification processes currently in use or planned for IGCC applications are oxygen-blown.
