Abstract:
A method of generating power, comprising:supplying a carbonaceous fuel substantially free of nitrogen and sulfur to a gas generator; supplying a first oxidizing fluid substantially free of nitrogen and sulfur to the gas generator at a sub-stoichiometric rate relative to the carbonaceous fuel; combusting the carbonaceous fuel with the first oxidizing fluid in the gas generator to produce a combusted gas; discharging the combusted gas to a first power take-off device; discharging at least a portion of the combusted gas from the first power take-off device to a reheater; combusting the combusted gas with a second oxidizing fluid substantially free of nitrogen and sulfur in the reheater to form a reheated gas; and discharging the reheated gas to a second power take-off device.
