Steam Engine with Horizontal Beam and Centrifugal Pump
"Steam Engines" are used to generate power in the form of mechanical energy (here the rotational movement of the Pulley that rotates the Centrifugal Pump) from thermal energy that vaporizes the water used in this cycle and then the steam can operate the piston in the cylinder to make it go forward and backward.
Then we use a simple mechanism called "Beam Engine Mechanism" to change this oscillation motion into rotary motion.
It should be said that "Steam engines" operate on the "Ideal Rankine Cycle"
Usually "Steam Power Plants" are used to generate electricity the same way weather it operates in a closed or open cycle but here we use it to rotate the centrifugal pump.
