How is a Rateau steam turbine structured______________?
Show answer Hide answer
Answer: C. pressure compounded impulse steam turbine
Explanation
A Rateau turbine uses multiple pressure stages each consisting of a nozzle ring and a moving impulse blade wheel. Steam pressure drops incrementally across each successive set of stationary nozzles increasing steam velocity progressively. This pressure compounded impulse design distributes total enthalpy drop across many stages to keep rotor speeds manageable. Pressure compounding divides total steam pressure drop into several smaller steps across multiple impulse stages. Each stage extracts kinetic energy from the steam before passing the remaining pressure to the next nozzle ring. Rateau turbines combine impulse blading principles with multi stage pressure staging to achieve high power outputs.
Reaction steam turbines feature continuous pressure drops across moving blades unlike pure impulse Rateau designs. Velocity compounded impulse turbine describes Curtis staging rather than pressure compounded Rateau turbines. Pressure velocity compounded turbines combine both staging methods rather than relying purely on pressure compounding.
