  • Oxy-fuel power plant operation - ScienceDirect

    A power plant's ability to adapt to load change requirement is very important. In a conventional air-blown plant, the load change requirement can be easily met with changes in fuel feed and combustion air flow rates. In an oxy-fuel plant, there is a need for several pieces of equipment to operate in unison to allow smooth load changes.
