ABSTRACT:
Steam resources, which may in some cases be of forms heretofore considered unusable because of low energy content or corrosive contamination, are used for electrical power and water treatment operations in installations where these formerly separate activities may be combined, with the waste products of one being a valuable input to the other. In one embodiment, discharge heat from a steam driven generating station and contaminated sewage water, each of which formerly presented costly or environmentally hazardous disposal problems, are combined to produce sterilized water reusable for crop irrigation. In another embodiment, fresh water enroute to a municipal utility system is used to condense discharge steam from generating station turbines for return to the boilers while sterilizing the water to reduce or eliminate cholorination requirements. Still another embodiment enables use of turbine driven generators to produce electrical power from corrosive geothermal steam sources without exposure of the turbines to such steam and sewage water may be sterilized as a by-product of the system. Means are also disclosed for the large scale pumping of water utilizing such steam energy.
