Abstract
A gas and steam turbine system includes a coal mill. A steam turbine has a water-steam loop. A gas turbine has an exhaust gas side supplying exhaust gas. A first heat exchanger is connected to the exhaust gas side of the gas turbine. A steam generator is connected downstream of the exhaust gas side of the gas turbine and upstream of the steam turbine in the water-steam loop for generating steam for the steam turbine. The steam generator has a furnace system connected downstream of the coal mill for supplying flue gas flowing through the steam generator. A second heat exchanger is connected to the coal mill. A first adjustable fractional quantity of the exhaust gas from the gas turbine after being cooled in the first heat exchanger, is delivered to the furnace system as combustion air. A second adjustable fractional quantity of the cooled exhaust gas is delivered to the second heat exchanger for heating air for the coal mill. A third adjustable fractional quantity of the cooled exhaust gas is admixed with the flue gas from the furnace system.
