Abstract
Kalina cycle is a power generation system for waste heat source of low temperature. This cycle is mainly used to a single heat source. By the way, there are extremely large potential of waste heat having different temperature region simultaneously. Therefore, this research examined the system which can use two or more heat sources effectively by a single system. Three different systems for two waste heat sources were proposed. Their three system were evaluated for waste water(70℃) and exhaust gas(300℃) as hot heat source. As the result, the power output of system which warming the separator latter part of a cycle directly by an exhaust gas was increased about 40 percent than one of conventional system.
