FIELD: electricity.
SUBSTANCE: invention can be used during creation of the electricity generating sources. Off-gas separation from the solid and / or liquid reaction products is carried out by burning in gaseous fuel of a metal selected from the group consisting of alkali metals, alkaline earth metals, Al and Zn, and mixtures thereof. In the reaction stage, the gaseous fuel is burned with the metal with formation of the off-gas, as well as other solid and / or liquid reaction products. In the separation stage, the off gas is separated from the solid and / or liquid reaction products, and additionally adding a carrier gas. Carrier gas is withdrawn as a mixture with the off-gas. Separation stage is carried out in a cyclone reactor comprising a reaction zone on which the supply devices for the gaseous fuel are located, for the metal M and for the carrier gas, a separation zone and a uniform evaporation chamber, as well as a discharge device for the off-gas and the carrier gas mixture. Gaseous fuel, the metal and the carrier gas can be combined and then together supplied into the reaction zone. In the uniform evaporation chamber, a discharge device for solid and / or liquid reaction products is located. Supply devices geometry is such that a cyclone is produced.
EFFECT: invention allows to improve the off-gas separating efficiency for its further use in a boiler and / or heat exchanger.
