Turbine Blade Design

Steam Turbine Turbo Set consist High, Intermediate and Low pressure of Turbine what convert heat energy from boiler to kinetic energy through turbines.

The kinetic energy created from nozzle and then enter the blades by impulse or reaction way that created mechanical energy.

Imagine how much size and design of the steam turbine turbo set which can rotated the shaft which couple to generator which produce 710MW. I should wait until turbine over-houl every 7 years but normally only turbine valves & bearing that be dismantle to maintenance, the blades rarely damage.

The turbine internally is mysterious but still can be prediction what the size and design like the blade.


First time we should calculate thermodynamic power plant cycle to find how much contribution of each turbines. In this time only HP (High Pressure) turbine that describe on details.




















This picture beside describe impulse and reaction way to created mechanical energy. In the HP Turbine is pure impulse turbine.






The Nozzle which created kinetic energy is not describe here. I only assume the steam velocity that be created from the nozzle.




















The blade velocity is defined from turbine rotating 3000rpm (50Hz) and transferred to angle velocity (multiply by 2*3.14*radius), the angle of steam enter to blade and other information to be assumed.
