CYLINDER STEAM TURBINE WITH REGULATORY COMPARTMENT Russian patent published in 2016 - IPC F01D9/00 F01D25/26 

FIELD: combined heat and power.

SUBSTANCE: invention relates to a power system and can be used when designing or upgrading steam turbines. Cylinder of a steam turbine with a control compartment, consisting of outer and inner shells of steam input pipes, annular steam supply chamber in the flow passage with unidirectional movement vapor stream consisting of the non-regulated pressure stages, clips, mounted in the outer casing of the cylinder. Inner cylinder body has several pressure stages, regulates compartment. Other unregulated stage are located in the outer cage of the cylinder barrel. Annular chamber steam divided by radial partitions, made of two parts with a clearance there between to steam supply section coinciding with the sections of the guide apparatus of the first stage formed by guide vanes with the lengthened towards the steam input chord and the geometry of the airfoil, which coincides with the same outline points of the blades guide vanes.

EFFECT: improved internal efficiency of the flow and the efficiency in the control compartment is achieved, with the exception of heating the cylinder body at high voltages from the internal steam pressure, ensuring the temperature of the cylinder body symmetry to the longitudinal axis, no nozzle boxes.
