WebCompounding of steam turbines is the strategy in which energy from the steam is extracted in a number of stages rather than a single stage in a turbine. A compounded steam turbine has multiple stages e.g it has more than one set of nozzles and rotors. These are arranged in series either keyed to the common shaft or fixed to the casing. WebMay 22, 2024 · Impulse Turbine – velocity compounding. A velocity-compounded impulse stage consist of a row of fixed nozzles followed by two or more rows of moving blades and fixed blades (without expansion). This divides the velocity drop across the stage into several smaller drops. In this type, the total pressure drop (expansion) of the steam take place …
