6/10/2020 7 Example 4 Steam at 40 bar, 400 o C enters a high-pressure turbine and expands to 8 bar. The extracted steam is then reheated to 400 o C and is expanded again to 10 kPa in a low-pressure turbine. Calculate the thermal efficiency of the steam cycle, if the specific heat of the boiler is 3000 kJ/kg. Assume the pump work is negligible and the steam cycle is ideal.

Lecture 2 - Steam Turbine | Power Station | Boiler
2020-11-4 · Boiler A boiler must functions properly as the boiler operation determines the quantity of steam available to produce the rotary motion of the turbine. When more power input for the generating process is required, because of an increased load on the system, the boiler must deliver more steam to the turbine.
