FIELD: chemistry.
SUBSTANCE: invention relates to the chemical industry. A device contains a drier (1) with a fluidised bed, a lignite-heated steam boiler, a steam turbine. Lignite is subjected to indirect drying in the drier (1). The dried lignite is cooled, crushed and supplied into the steam boiler. Flue gas from the steam boiler undergoes absorption purification to separate CO2. The device of flue gas purification includes an absorption column (14), a desorption column (12), a reboiler (13). Energy, required for absorption purification is partially taken from the drier (1).
EFFECT: invention makes it possible to reduce the amount of low-pressure steam, required for flue gas purification.
