In Velocity Compounding Steam Is Passed Through?

This high-velocity steam first enters the first ring of moving blades where some portion of velocity is absorbed. Then it passes through the next ring of fixed blades. The fixed blades changed steam direction and direct to the second ring of moving blades.

What is velocity compounding of steam turbine?

Compounding of steam turbines is the method in which energy from the steam is extracted in a number of stages rather than a single stage in a turbine. In all turbines the rotating blade velocity is proportional to the steam velocity passing over the blade.

What happens in velocity compounding?

In velocity-compound staging a set of stationary nozzles is followed by two sets of moving blades with a stationary row of impulse blades between them to redirect the flow. Ideally this allows twice as much power to be extracted than from a single impulse stage for…
