[Class 110 (iii)] Steam generated in water jackets of combustion chambers C is used in the combustion turbine A, or may be directed to a separatesteam turbine driving the same shaft B, or another shaft. Air is supplied by a compressor D to an inlet c, and fuel by a pump C. A valve E controls the entry of the gases into the turbine. Water is sprayed into each jacket by a pump G. Steam from the jackets may be collected in an accumulator G and supplied under control of a valve g to the turbine, or to another. Steam may also be injected through nozzles h in a condenser H. The accumulator may be dispensed with.
