Abstract
A power plant includes a power machine and a flue gas flow path following downstream of the power machine. A flue gas flow path is scavenged with fresh air before the flue gas flow path is acted upon with flue gas. To carry out the scavenging operation, air is extracted from a pressure accumulator and the air is introduced into the flue gas flow path downstream of the power machine. The power machine can be an exhaust gas heat exchanger.
Claims8
A power plant, comprising:
- a pressure accumulator;
- at least one power machine;
- an exhaust gas heat exchanger downstream of the power machine;
- a flue gas flow path extend fluidly from the at least one power machine to the exhaust gas heat exchanger;
- and
- a line leading from the pressure accumulator to the flue gas flow path having a shut-off member.
