ABSTRACT:
A sequence of activating and deactivating arcuate nozzle chambers which together form a structure for admitting steam into a steam turbine and directing it through turbine blades. At least one small and one large nozzle chamber are cooperatively activated and deactivated to provide maximum turbine efficiency. After minimum admission operation has been achieved, a small nozzle chamber disposed arcuately adjacent the activated nozzle chambers is increasingly activated as load is increased. When the small nozzle chamber has been fully activated and load on the turbine increases further, the large nozzle chamber is increasingly activated with load. At a predetermined degree of activation of the larger nozzle chamber, the small nozzle chamber is increasingly deactivated as the large nozzle chamber is increasingly activated. When the large nozzle chamber has been completely activated and the load on the turbine increases further, the small nozzle chamber is again increasingly activated as the load increases. The most efficient turbine operation obtains when the small nozzle chamber is deactivated simultaneously with activation initiation of the large nozzle chamber. Suitable relative disposition of the nozzle chambers allows avoidance of double shock operation of the turbine blades when the previously described method is practiced.
