FIELD: power engineering.
SUBSTANCE: circulation reactor of oxygen firing with a fluidised bed comprises a chamber (15) of the reactor and a gas distribution device (50), designed in the lower section of the reactor chamber for gas introduction into the reactor chamber. Besides, the gas distribution device comprises the first system (70) of gas supply and the second system (75) of gas supply for introduction of gas enriched with oxygen into the reactor's chamber (15). The first system (70) of gas supply comprises the first wind box (71), and the second system (75) of gas supply comprises the second wind box (80), and at the same time the first wind box has a common wall (77) with the reactor chamber, and the second wind box arranged under the first wind box, has a common wall (76) with the first wind box.
EFFECT: reduced content of carbon dioxide in burning of carbon-containing fuels.
