Thermal power plant has heat exchanger arrangement arranged to heat second working fluid before it enters second vapor generator using waste heat from first vapor generator

摘要

The device has a first vapor generator (12) for evaporating a first working fluid connected to a first vapor power machine (14) and a second vapor generator (20) connected to the first machine and to a second vapor power machine (32). The second vapor generator cools the working fluid from the first machine and evaporates a second working fluid to drive the second machine. A heat exchanger arrangement (40) is arranged and designed to heat the second working fluid before it enters the second vapor generator using waste heat from the first vapor generator.
