Boiler and Condenser Pressures - Rankine Cycle

Boiler Pressure. An increase in the boiler pressure is in the result limited by material of the reactor pressure vessel. The case of the increase in the average temperature at which energy is added by heat transfer, requires either a superheating of steam produced or an increase in the pressure in the boiler (steam generator).
