Abstract
A gas turbine set with sequential combustion is provided with a waste-heat boiler suitable for the generation of synthesis gas. The gas turbine set then operates with chemical recouperation of the exhaust-gas heat. By means of such a power plant, efficiencies can be achieved which come close to those of combined cycle plants. The highest efficiencies are achieved when, in a gas turbine set with sequential combustion, the reactor gas is fired, for as large a part as possible, in a combustion chamber of a highest pressure stage. In order to achieve a particular rate of conversion of hydrocarbon-containing crude fuel and superheated steam into synthesis gas, the reactor has to be brought to a minimum temperature which may be above the temperature of the expanded working medium of the gas turbine. This temperature increase can be ensured by means of additional firing. The additional firing may also be used for starting the production of synthesis gas when a starting-air device is present.
