ABSTRACT:
A steam generation apparatus includes a primary source of hot water supplied to an enclosed hot water receptacle maintained at a pressure of approximately 300 psi. Supply and return lines pump the hot water in a recirculating manner through a serially connected supplemental heating device until the hot water has reached a temperature of substantially 400.degree. F. whereupon a thermal valve associated with the supplemental heating device opens to deliver the heated water to an expansion tank. Steam formed within the expansion tank is transmitted through a steam outlet line to appropriate using apparatus. The initial hot water source may alternately include industrial by-product heated waste water on a primary heating station serially connected between a water supply and the enclosed hot water receptacle. Water condensed in the expansion tank is recycled to either the hot water receptacle or primary heating station. Solar energy collector devices are readily adaptable for providing either or both the primary and supplemental heating of the water.
