Methods and systems for steam production are provided. Methods include providing feedwater having an electrical conductivity of less than 200 ?S/cm to an electrode boiler, and converting the feedwater to saturated steam by the electrode boiler. The saturated steam is provided as a first fluid to a heat exchange component. Water having an electrical conductivity of more than 200 ?S/cm is provided to the heat exchange component as a second fluid, where the second fluid is heated through indirect thermal transfer with the saturated steam to generate wet steam. The saturated steam is at least partially condensed in the heat exchange component through the indirect thermal transfer with the second fluid. At least a portion of the thus obtained condensed fluid is fed back to the electrode boiler for use as part of the low-conductivity water to generate said saturated steam.

A steam generator that reduces the thermal and hydraulic unevenness in the steam generator, improves the filling capacity of the steam generator with heat exchange tubes, organizes an economizer portion of the heat exchange surface in the steam generator, and reduces the concentration of corrosive impurities in the weld zone of the primary circuit to the horizontal shell. To solve the task in such steam generator containing the horizontal shell and other component, the heat exchange tubes are located in vertical planes, and the inlet and outlet manifolds of the primary circuit are arranged horizontally. The steam generator can also be equipped with at least two output manifolds of the primary circuit furthers, the feed water dispenser can be located below the heat exchange tubes of the steam generator.

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 boiling-water geothermal heat exchanger 1 is provided with a water injection pipe 2 which is installed underground and to which water is supplied from the ground and a steam extraction pipe 3 which is installed underground so as to be in contact with the water injection pipe 2 and has a plurality of ejection ports 5, in which a pressure inside the steam extraction pipe 3 is reduced to the vicinity of a pressure required by a turbine 6, high-pressure hot water which is produced by supplying heat from a geothermal region 4 to water inside the water injection pipe 2 is changed to a single-phase flow of steam inside the steam extraction pipe 3 present underground via the ejection ports 5, and the single-phase flow of steam is extracted on the ground. And in the boiling-water geothermal heat exchanger 1, a heat insulation portion is formed at a part which is in contact with a low-temperature region close to the ground surface, and the heat insulation portion is such that the level of water supplied to the water injection pipe 2 is lowered to form an air layer at an upper part of the water injection pipe 2.
