PURPOSE:To improve the evacuating function with respect to noncondensable gas and provide satisfactory power recovery efficiency by connecting both a storage tank of working fluid and a secondary condenser which is to separate working fluid from noncondensable gas to a primary condenser. CONSTITUTION:A waste heat recovery device consists of a displacement type expander 12, an evaporator 11 which evaporates working fluid and a primary condenser 14 which condenses working fluid. Both a secondary condenser 17 which is to separate liquefied working fluid from noncondensable gas and a storage tank 18 of working fluid are connected to the primary condenser 14. The upper part of the storage tank 18 and the outlet 19 of the secondary condenser 17 from which noncondensable gas is discharged are connected by a communication pipe 10 serving to discharge noncondensable gas therefrom. The evacuating function with respect to noncondensable gas can thereby be improved and the power recovery efficiency be also improved. |
