  • Boiler and Condenser Pressures - Rankine Cycle

    2019-7-14 · Boiler and Condenser Pressures. As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles.
