turbine pressure Steam

The invention relates to the field of power engineering and can be used in the design and modernization of the cylinders of medium pressure steam turbines operating with reheat steam and turbines for nuclear power plants. The medium pressure cylinder of a steam turbine includes a housing with a chamber propusk, the guide apparatus of the first stage behind him with a clearance of rotor blades of the first stage with a peripheral band, the sides of the stator, placed radially above the brace blades of the first stage, mounted on the stator side of the diaphragm of the second stage so that between the shell and the casing is formed an annular cavity, and between the shell and the butt guide device is made of an axial gap. When this axial clearance between the output edges of the guide vanes and the inlet edges of the blades of the first stage is carried out within z*= z/(t1sin1) = 1.5 to 2.5, where z is the distance from the output edges of the guide vanes upstream of the inlet edges of the blades along the axis of the turbine; t1- step guide vanes;1- the exit angle of the steam flow from the guide vanes, and an annular Polo the
