The present invention is a system and method of power medium expansion that functions with a rate of efficiency higher than systems found in prior art. Novel features of the system increase the overall efficiency with the use of a power medium that begins the cycle in the liquid state and enters the gaseous state. An additional novel feature is the use of additional heat that may also increase the overall cycle efficiency. Another additional novel feature is recuperating energy that can supplement the phase change of the power medium along with isolating the components from the ambient.

Processes for recovering electrical power from a process unit waste heat steam generation system are described. A power-recovery turbine reduces the pressure of a stream of superheated steam to a pressure lower than that needed by the steam reboiler for use in other process units or equipment in the plant.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

The heat cycle facility includes: a first vaporizer that vaporizes a first liquid heating medium by combusting fuel; a first motive power generator that generates motive power by using as a drive fluid a first gas heating medium obtained at the first vaporizer; a condenser that condenses the first gas heating medium discharged from the first motive power generator by heat-exchanging the first gas heating medium for a second liquid heating medium; a circulator that pressurizes the first liquid heating medium obtained at the condenser and supplies the pressurized first liquid heating medium to the first vaporizer; a second vaporizer that produces gaseous ammonia by heat-exchanging the second liquid heating medium for liquid ammonia; and a supplier that supplies the liquid ammonia to the second vaporizer.

A power generation facility in an embodiment includes: a boiler; a high-pressure turbine to which steam generated in the boiler is introduced; a low-pressure turbine provided downstream of the high-pressure turbine; and a condenser that condenses steam discharged from the low-pressure turbine. The power generation facility further includes: a feed pipe that leads feedwater in the condenser to the boiler; a heat storage and steam generation device that has a heat storage function that uses surplus energy generated in an own system to store heat, and a steam generation function that has part of feedwater led by the feed pipe introduced thereinto and turns the feedwater into steam by the stored heat; and a steam supply pipe that supplies steam generated in the heat storage and steam generation device to an own system.

A control system controls a temperature of a fuel which is supplied to a combustor of a gas turbine via a fuel gas heater, which heats the fuel of the gas turbine, by adjusting a flow rate of heated water which is supplied to the fuel gas heater. The control system includes a water flow rate adjusting unit that adjusts the flow rate of the heated water which is supplied to the fuel gas heater based on a difference between a target temperature of the fuel and the temperature of the fuel on an outlet side of the fuel gas heater.
