System and method to improve boiler and steam turbine start-up times

Abstract:

A system for reheating a power generation system including a boiler and a mixer fluidly coupled to the boiler, a turbine first section operable to receive steam from the boiler at a first temperature. The turbine supplies steam at a second temperature to the boiler or mixer. The system also includes a first flow control valve operable to control a flow of steam through the turbine, and a sensor the sensor operable to monitor at least one operating characteristic in the boiler system. The system further includes a control unit configured to receive the monitored operating characteristic and control at least the first flow control valve, to control the amount of steam directed through the turbine.
