Abstract

Methods and systems for steam production are provided. Methods include providing feedwater having an electrical conductivity of less than 200 μS/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 μS/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.
