RANKINE CYCLE DEVICE AND COGENERATION SYSTEM

摘要

A Rankine cycle apparatus (20) includes a pump (23), an evaporator (24), an expander (21), and a condenser (22). The evaporator (24) has a plurality of heat transfer tubes (28) arranged in rows in a flow direction of a high-temperature fluid to be heat-exchanged with a working fluid. The heat transfer tube (28) located in a most upstream row in the flow direction of the high-temperature fluid is defined as a most upstream heat transfer tube (28k). For example, the most upstream heat transfer tube (28k) forms an inlet of the evaporator (24) so that the working fluid flows into the evaporator (24) through the inlet and first passes through the most upstream heat transfer tube (28k).
