System to achieve full combustion turbine load in HRSG limited combined cycle plants

A method of suppressing steam production in heat recovery steam generator comprising:

• diverting a flow of feed water upstream from an economizer series;
• controlling the volume of the diverted flow of feed water and bypassing a portion of the economizer series from receiving the controlled volume of diverted flow of feed water;
• returning the controlled volume of diverted flow of feed water to a downstream portion of the economizer series;
• heating the controlled volume of diverted flow of feed water in said downstream portion of the economizer series to reduce an approach temperature;
• transferring the heated controlled volume of diverted flow of feed water to a high pressure steam drum in fluid flow communication with an evaporator;
• mixing the heated controlled volume of diverted flow of feed water with heated steam drum water reducing the temperature of mixed water in the high pressure steam drum;
• passing the mixed water from the high pressure steam drum to the evaporator producing steam;
• reducing the rate of steam production for the mixed water in the evaporator, reducing the steam pressure in the evaporator, and decreasing the steam flow exiting the evaporator;
• transferring the steam flow exiting the evaporator to a superheater;
• and
• metering the steam flow exiting the superheater.
