Abstract: A power plant system can comprise a first gas turbine having a first efficiency to produce a first exhaust flow, a first electrical generator driven by the first gas turbine, a first heat recovery steam generator to receive the first exhaust flow and generate a first steam flow, a second gas turbine having a second efficiency less than the first efficiency to produce a second exhaust flow, a second electrical generator driven by the second gas turbine, and an exhaust gas conditioning device to reduce temperature of the second exhaust flow, a steam turbine driving a steam electrical generator to receive the first steam flow. The second gas turbine can be selectively operated to generate electricity with the second electrical generator under peak loading conditions when a sum of output from the steam electrical generator and the first electrical generator are less than an electrical demand from a grid.

Abstract: A combined power generation system improves the generation efficiency of a pressure difference power generation facility by using at least one of air for cooling a turbine of a gas turbine power generation facility and waste heat of flue gas generated by the gas turbine power generation facility. Working fluid to be used in a supercritical fluid power generation facility is cooled by using cold energy of liquefied natural gas. The system includes an air discharge channel via which compressed air is discharged; a fuel gas heater for heating the natural gas to be introduced into the pressure difference power generation facility by performing a heat exchange between the discharged air and the natural gas being heated; and a cooling air inflow channel for guiding the cooled air passed through the fuel gas heater to a turbine of the gas turbine power generation facility.

Abstract: A method for the short-term adjustment of the output of a steam turbine of a combined-cycle power plant, includes: opening, respectively closing, a backed-up turbine valve of a pressure stage, according to a required change in output; comparing a desired pressure with a pressure measurement upstream of the turbine valve to measure pressure of steam mass flow flowing into the pressure stage; and opening, respectively closing, a feed line for introducing a variable proportion of water into the steam mass flow as soon as the pressure falls below or exceeds the desired pressure; the variable proportion of water is introduced into the steam mass flow until an adjusted desired steam temperature is reached, which is determined from the difference between a basic specified desired steam temperature and the default value of a controller which operates at least proportionally and evaluates the difference between the pressure measurement and the desired pressure.

Abstract: A system for processing saltwater or brackish water while recovering energy otherwise wasted in electricity generation by a natural gas generator or turbine. Heat in the generator exhaust is used to directly heat and process the water in the saltwater or brackish water into high quality steam, separating the majority of salt and contaminants from the water, and leaving potable water that can be permitted and released to the environment or sold for agricultural or industrial use such as oilfield activities. The system also captures and liquefies CO2 in the generator exhaust.

Abstract: A gas turbine engine includes a primary flowpath fluidly connecting a compressor section, a combustor section, and a turbine section. A heat exchanger is disposed in the primary flowpath downstream of the turbine section. The heat exchanger includes a first inlet for receiving fluid from the primary flowpath and a first outlet for expelling fluid received at the first inlet. The heat exchanger further includes a second inlet fluidly connected to a supercharged CO2 (sCO2) bottoming cycle and a second outlet connected to the sCO2 bottoming cycle. The sCO2 bottoming cycle is an overexpanded, recuperated Brayton cycle.
