The experience of operating powerful energy steam turbines has clearly shown that a significant share of losses with reduced steam consumption is accounted for by the steam distribution system, which is characterized by intensive throttling of steam

Control valves are actuating elements of a steam turbine control system; the quality of their performance directly affects the reliability of the overall steam turbine unit. Accordingly, these valves must meet very stringent requirements. Among the f

Among the characteristics of the power-generating steam turbines, the specific metal intensity ranks very high. Low-pressure cylinders (LPCs) that use a two-tier Baumann stage have the lowest value of this parameter. The Baumann stage allows a 50% in

The specific metal consumption is a metal amount spent per an installed power unit. This criterion is important for turbine quality assessment. This criteria drops rapidly when a turbine power increase remarkably leaves behind its total metal consump

Annotation The O. Reynolds equation is the only one in the scientific world that is derived from equations that are valid for a medium that has completely different surface forces than the surface forces in real turbulent flows. It is shown that by v
