Device for increasing efficiency of drive of thermal power station, has expander e.g. piston expander, provided at exhaust pipe, where hot exhaust gas flow is emitted into atmosphere or to heat consumer through outlet of device

摘要

The device (1) has an expander (4) e.g. piston expander, provided at an exhaust pipe (3) and coupled with a compressor (9) e.g. turbo compressor, by a shaft (10), where low pressure is generated in the exhaust pipe. A hot exhaust gas flow is transversely sucked from the exhaust pipe, the expander, a vacuum pipe (5), a heat exchanger (6), a compressor supply line (8) and the compressor by the low pressure. The hot exhaust gas flow is emitted into atmosphere or to a heat consumer through an outlet of the device. An independent claim is also included for a method for increasing efficiency of a drive of a current- and heat generator.
