| 摘要 | PURPOSE:To increase the ratio of power recovery without the need for enlarging the scale of a waste heat recovery system by sending both steam and lubricating oil into a displacement type expander and directly exposing the steam and the oil to each other inside said expander. CONSTITUTION:A displacement type expander 12, an evaporator 10 which evaporates working fluid, and a fine temperature difference heat exchanger 11 which heats lubricating oil to a high temperature are mounted inside a waste heat recovery system. The recovery system also contains a condenser 20 which condenses steam discharged from the displacement type expander 12 and a primary to the third pump 21-23 which circulate working fluid and lubricating oil. Steam and lubricating oil which are sent into the displacement type expander 12 are directly exposed to each other inside said displacement type expander, whereby superheating steam of working fluid. The ratio of power recovery can thereby be increased without the need for enlarging the scale of the waste heat recovery system. | ||||||
