FIELD: steam generation.
SUBSTANCE: invention relates to energetically effective configurations of power plants that contain steam boilers, which in turn operate on fossil fuels. Power plant includes fossil fuelled boiler (10), air supply system, flue gas system and condensate system.
EFFECT: unitary flue gas heat exchanger (54) covers bypass line (22) in the flue gas system and the condensate system in such a way as to improve the thermal efficiency of a power plant while minimizing the complexity.
