Question 12.19: A steam power plant operates on a theoretical reheat cycle. ...
A steam power plant operates on a theoretical reheat cycle. Steam at boiler at 150 bar, 550°C expands through the high pressure turbine. It is reheated at a constant pressure of 40 bar to 550°C and expands through the low pressure turbine to a condenser at 0.1 bar. Draw T-s and h-s diagrams. Find :
(i) Quality of steam at turbine exhaust ;
(ii) Cycle efficiency ;
(iii) Steam rate in kg/kWh.
