Sensitivity Analysis Of Oxyfuel Power Plant System

Jul 01, 2015 The flue gas temperature is usually set relative to its acid dew point to avoid corrosion issues in the ducting and stack and the coal mill system in a power plant. Due to a smaller flue gas amount in an oxy-firing plant, a rise on flue gas temperature is expected, which in turn affects the overall heat balance in the system.
