ABSTRACT:
A system is disclosed for increasing the main steam temperature in a boiler/turbine installation to the maximum level consistent with safe operation of the installation. The difference between the main steam temperature and a system parameter is determined and used as an index to adjust the main steam temperature set point upward or downward. The system parameter selected for comparison with the main steam temperature may be the allowable variance between the main steam temperature and the main steam temperature set point or may be a "safety margin" temperature selected so as to be below the maximum allowable temperature for the installation.
