METHOD TO OPERATE POWER PLANT WITH INTEGRATED GASIFICATION, AND ALSO POWER PLANT Russian patent published in 2012 - IPC F02C3/28 

FIELD: power engineering.

SUBSTANCE: carbon-containing fuel is gasified and in the form of a synthetic gas is supplied for burning to a burner attached to a gas turbine, besides, at the process temperature, oxygen is separated from air by means of a membrane, oxygen-depleted air is produced, separated oxygen is supplied to a gasifying device for reaction with a fossil fuel, to maintain the required temperature of the process, heating energy is supplied to the membrane, heating energy is partially received from the synthesis gas, and partially - from oxygen and/or oxygen-depleted air in heat exchange with air, and the heated air is supplied to the membrane.

EFFECT: invention makes it possible to increase efficiency of heating air supplied to a membrane.
