  Principle of steam turbine:

  The steam energy is converted mechanical work by expansion through the turbine. Expansion takes place through a series of fixed blades(nozzles) and moving blades. In each row fixed blade and moving blade are called stage. produced by: KorynenkoMykyta, LyubovMykhaylo

  What exactly is the turbine?

  Turbine is an engine that converts energy of fluid into mechanical energy The steam turbine is steam driven rotary engine. produced by: KorynenkoMykyta, LyubovMykhaylo

  Impulse steam turbine:

  The basic idea of an impulse turbine is that a jet of steam from a fixed nozzle pushes against the rotor blades and impels them forward. The velocity of steam is twice as fast as the velocity of blade. Pressure drops take place in the fixed blade (nozzle). produced by: KorynenkoMykyta, LyubovMykhaylo

  Слайд 7

  Reaction steam turbine:

  A reaction turbine utilizes a jet of steam that flows from a nozzle on the rotor. Actually, the steam is directed into the moving blades by fixed blades designed to expand the steam. The result is a small increase in velocity over that of the moving blades. produced by: KorynenkoMykyta, LyubovMykhaylo
