Abstract
A power plant with a fossil fuel fired boiler, an air feed system, flue gas system and condensate system. A unitary flue gas heat exchanger spans a bypass line in the flue gas system and the condensate system so as to improve the thermal efficiency of the power plant while minimising complexity.
Claims10
A power plant comprising:
- a fossil fuel fired boiler;
- an air feed line for feeding air into the boiler;
- a flue gas line connected to the boiler for exhausting flue gas from the boiler;
- an air preheater in both the air feed line and the flue gas line configured and arranged to exchange thermal energy from flue gas exiting the boiler to air fed into the boiler;
- a bypass line forming part of the flue gas line arranged to bypass the air preheater;
- a first condensate line connected to the boiler for feeding condensate into the boiler having a plurality of preheaters;
- a second condensate line with first and second distal ends connected the first condensate line;
- and
- further comprising a flue gas heat exchanger, spanning the bypass line and the second condensate line, configured and arranged to transfer thermal energy from flue gas to condensate.
