FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Power plant with an oxygen-fired boiler with coal heating comprises a steam coil oxygen pre-heating device located on the air separation unit of the oxygen line. Plant is thermally integrated with the condensate system. Thermal energy for the steam coil oxygen preheating device is provided by a tapping line connected to an intermediate pressure steam turbine tapping port. Tapping line of the steam coil oxygen preheating device fluidly connects the steam coil oxygen preheating device to the point of the Rankine steam cycle in fluid communication within the condensate system.
EFFECT: invention improves the efficiency of the power plant.
