Abstract
Method and system for adjusting a measured reheat outlet steam temperature ('R') to approximate a reheat outlet steam temperature setpoint ('R') in a boiler. An Ris compared to an R. If the Ris less than the Rand a position of a fuel nozzle tilt (“TILT”) is below a high limit of the fuel nozzle tilt (“TILT”), the TILTis increased while a flow rate of a secondary flue gas recirculation (“SFGR”) is kept constant. If the Ris less than the Rand the TILTis at the TILT, the SFGRis increased. If the Ris greater than the Rand the SFGRis greater than a low limit of flow rate of the SFGR (“SFGR”), the SFGRis decreased, while the TILTis kept constant. If the Ris greater than the Rand the SFGRis at the SFGR, the TILTis decreased.
