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.

A combined power generation system is provided. The combined power generation system includes a gas turbine configured to combust fuel to generate a rotational force, a heat recovery steam generator (HRSG) configured to heat feedwater using combustion gas discharged from the gas turbine and include a high-pressure section, a medium-pressure section, and a low-pressure section with different pressure levels, a fuel preheater configured to heat the fuel supplied to the gas turbine and include a primary heating part and a secondary heating part, and a high-pressure feedwater supply pipe connected to the high-pressure section to supply high-pressure feedwater to the secondary heating part.
