Question

List the advantages are obtained if superheated steam is used in steam prime movers.

Answer 1

Adding heat at higher temperature will increase the mean temperature of heat addition so an increase in super-heat at constant pressure (as shown in figure from 1 to 1′)increases the and hence the cycle efficiency. Moreover increase the super-heat will shift the expansion line(as shown in above fig.
