    摘要: A combined cycle power generation system (10) includes a steam turbine (14, 16, 18), a combustion system (12) including a compressor (24), a combustion chamber (26), a gas turbine (28), and a HRSG (20) to generate steam with energy from the combustion turbine. A flow line (60, 70) passes superheated steam into the combustion chamber. In an associated method a first source of power is provided via a combustion process having a variable reaction temperature in a first turbine. A second source of power is provided via a second turbine. Components of the system are placed in a mode of increasing power output with steam generated from the HRSG, during which a portion of the steam is provided into a combustion chamber associated with operation of the second turbine.

The system includes a boiler fluidly coupled to the input charge flow, an energy conversion device fluidly coupled to the boiler, a condenser fluidly coupled to the energy conversion device, a pump fluidly coupled to the condenser and the boiler, an adjuster that adjusts at least one parameter of the Rankine power cycle subsystem to change a temperature of the input charge exiting the boiler, and a sensor adapted to sense a temperature characteristic of the vaporized input charge. The system includes a controller that can determine a target temperature of the input charge sufficient to meet or exceed predetermined target emissions and cause the adjuster to adjust at least one parameter of the Rankine power cycle to achieve the predetermined target emissions.

    摘要: In certain embodiments, a system includes a physical computing device having a tangible machine-readable medium including code. The code is adapted to determine an efficiency of a section of a steam turbine based on a relationship between enthalpy difference values and leakage flow rate values between adjacent sections of the steam turbine. The relationship includes a point of equalizing an enthalpy of the leakage and an enthalpy at a destination of the leakage.

The reheater includes a first section disposed downstream of and a second section disposed upstream of the supercritical evaporator along the exhaust gas flow path. Cool reheat steam from the steam turbine system is received by the first reheater section and steam leaving the first reheater section is supplied to the second reheater section upstream of the supercritical evaporator.
