Boiler and Condenser Pressures - Rankine Cycle

Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the

What is Flash Steam? - Forbes Marshall

At atmospheric pressure, water boils at 100 Deg. C. Inside steam piping or any pressurized vessel, steam is generally utilised at a pressure above the atmospheric pressure. When this steam loses its heat either by transferring it to the product being heated or by radiation loss to the environment, condensate is formed.

Basic Steam Theory - Steam Pressure

While at atmospheric pressure (101.3 kPa) water boils when it reaches the temperature of 100 deg.C. we find that at a pressure of, for example, 690 kPa the boiling point has gone up to 169.95 deg.C. You will readily see that to keep the water boiling (and giving off steam) at this higher temperature it has to be supplied with a greater

Boiler Pressure and Central Heating System Pressure -- Why

Where an external expansion vessel is fitted, and the cold boiler pressure is 1 bar, you may see a rapid rise in boiler pressure as the system heats up. This is because, with a pre-charge pressure of 1½ bar, the expansion pocket in the external vessel is only available once the boiler pressure reaches 1½ bar.
