WebbA steam turbine is a rotating machine that converts the energy of the steam (by virtue of its pressure and temperature) into the mechanical energy of the rotor. For this purpose, the pressure energy of the steam is converted into kinetic energy and then it is utilized to move the moving blades that are mounted onto the rotor of the turbine. WebbAn impulse turbine uses steam impinging upon the turbine rotor blades to rotate the turbine rotor. As the velocity of the steam is directly proportional to the amount of energy transferred to the rotor, the velocity of the steam is increased using nozzles prior to it impinging upon the rotor blades. Impulse Turbine Design
