Comparison between Impulse and Reaction Steam Turbines

In Impulse Turbine, steam totally extends in the spout itself. Consequently its weight stays steady on the two finishes of the moving sharp edges.

In Reaction Turbine, Fixed sharp edges go about as spouts. Consequently steam grows both in settled and moving cutting edges constantly as it disregards them. In this manner the weight drop happens progressively and ceaselessly over both the settled and moving edges.

In Impulse Turbine, Blades Passage is of consistent cross segment territory, as there is no extension of steam.

In Reaction Turbine, Blade entry is of variable cross-sectional zone (joining type) because of extension of steam.

In Impulse Turbine, As weight stays consistent in moving cutting edges, the general speed of steam disregarding the moving sharp edges stays steady

In Reaction Turbine, Continuous development of steam implies relative speed in the moving cutting edges increments.

In Impulse Turbine, Blades are of symmetrical profile types : consequently, assembling of cutting edge is straightforward.

In Reaction Turbine, The sharp edge shapes are of aerofoil and non-symmetrical sort; subsequently fabricating is troublesome.

In Impulse Turbine, Because of vast weight drop, the steam speed and the running rate are high.

In Reaction Turbine, Due to little weight drop, the steam speed and the running pace are low.

In Impulse Turbine, Because of vast weight drop in the spouts, the quantity of stages are less. The extent of a motivation turbine for power yield is nearly little.

In Reaction Turbine, Because of little weight drop in each stage, the quantity of stages are more for a similar weight drop. Subsequently the measure of the response turbine for a similar power yield is extensive. Response turbines are multi-arrange turbines as it were.
