CYCLE OF STEAM ENGINE

Modified rankine cycle is used for reciprocating steam engine because of loss of negligible amount work(given by area 2-2’-3-2 as shown in figure). There is reduction in the stroke length which reduces the size cylinder which further reduces material used and cost.

WORKING OF STEAM ENGINE

Steam exerts pressure over the piston and piston reciprocates inside the cylinder. The reciprocating motion of piston is converted into the circular motion pf crankshaft through piston rod and connecting rod. The D-slide valve again gets the reciprocating motion from the crankshaft by means of an eccentric. The circular motion of crankshaft is converted into the reciprocating motion of the slide valve through the eccentric, eccentric rod and the D-slide valve rod.
