A system for warming 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 a first heat exchanger operably connected to receive the heated steam at the second temperature from the output of at least the first section of the turbine and transfer heat to at least one of water and steam in the boiler or the mixer, feedwater for the boiler, and a thermal energy storage system. The system further includes a control unit configured to receive the monitored operating characteristic and control the amount of steam directed through the turbine.

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

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.

A modification of a power boiler is disclosed, which comprises water walls enclosing the furnace for heating water and producing steam; a superheater system provided above the furnace for superheating steam; an additional superheater mounted in the furnace for further superheating steam from the superheater system. A modifying method of a power boiler is also disclosed, which comprises steps of mounting an additional superheater on water walls in a furnace; connecting an output of a superheater system to an inlet of the additional superheater; and connecting an outlet of the additional superheater to a turbine for producing power at an improved plant heat rate.

Boiler and modifying method thereof

A water recirculation system for a steam power plant includes a tapoff line which receives water from a downcomer, and an economizer link which receives water from the tapoff line and transports the water to an economizer.
