The working of the steam turbines in the United States. A drawing depicts the first stage of the working of the steam turbine. The steam jets strike the blades of the turbine. The blades receive the steam and change their direction. The spindles are driven through the process. A man demonstrates the working of the steam turbine through the tea kettle. A tea kettle is placed to boil the water. The steam comes out of the kettle and revolves the paddle wheel kept nearby. The impulse stage of modern steam turbine being demonstrated. The blades being forced to move due to the pressure of the steam. The direction of steam is changed and it gives more power to the revolving spindles. A man works on the steam turbine. Steam coming out of a tea kettle. The steam moves through stationery blades first and then through the blades in motion. The steam enters from the boiler to the turbine. It then passes through the nozzle. The quantity of the steam at this stage should be constant. The turbine rotates because of the steam and it turns the shaft. The centrifugal force works at this time. The valve in the turbine opens. The small piston moves down. The large piston moves upwards. The force moves the valve. The speed of the turbine is decreased. The quantity of steam is increased and the speed thus increases.
