Abstract

As fresh water resources are increasingly scarce, water-saving technologies are quite important for power plant in water leaking area. Conventional techniques for saving water in power plant include air-cooled condensers (ACCs) of power generating units, air-cooling of auxiliary cooling water, dry ash removal and desulphurization of activated coke, etc. Conventional water-save technologies will cost much more than non-water-saving technologies. A new water-saving technology named Getting Water from Lignite (GWFL) is proposed in this article. This technology is applied to coal with more than 30% moisture content, such as lignite. GWFL technology not only recycles water from coal, but also save the heat from the steam out of boiler. It is the most appropriate technology for high moisture coal fired power generation. Other categories of water-saving technologies shall be chosen based on the drought rate and construction budget.
