------------------------------------

Turbine, there are some fixed nozzles and moving blades are present on a disc mounted on a shaft. Moving blades are in symmetrical order. The steam enters the turbine casing with some pressure. After that, it passes through one or more no. of fixed nozzles into the turbine. The relative velocity of steam at the outlet of the moving blades is same as the inlet to the blades. During Expansion, steam's pressure falls. Due to high-pressure drop in the nozzles the velocity of steam increases.

This high-velocity jet of steam flows through fixed nozzles and it strikes the blade with constant pressure. An impulse turbine, steam produced only impulsive force to the blades. Now blades are starting to move in the same direction of the steam flow. Due to change in momentum, turbine's shaft is starting to rotate.
An example of Simple Impulse turbine is a DA-Laval turbine.
