<p>The inlet stage, particularly control stage has a nozzle ring for impinging an impeller with steam. A steam mass flow density is passed through the nozzle on its circumference. The sizes or the distances of the nozzles of the nozzle ring are varied against each other on its periphery. The sizes of the nozzles of the nozzle ring, are decreased towards a steam inlet in the nozzle ring. Independent claims are also included for: (1) a control stage with a nozzle ring, particularly four controlled subrings; and (2) a steam turbine with an impeller and a nozzle ring for receiving a regulating wheel.</p> |
