FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Power plant with a coal-fired oxygen boiler contains a circuit for thermal integration of the air separation unit. Air separation unit comprises a desiccant heater in which a withdrawal line connects the steam extraction port with the desiccant heater. Drain line of the dryer heater connects the regeneration heater with the Rankine steam cycle point in the condensate system.
EFFECT: invention makes it possible to increase the efficiency of energy production and to reduce the level of emissions of gases into the environment.
