A pressure vessel is defined as a container with a pressure differential between inside and outside. The inside pressure is usually higher than the outside, except for some isolated situations. The fluid inside the vessel may undergo a change in state as in case of steam boilers, or may combine with other reagents as in case of a chemical reactor.

The lowest feasible condenser pressure is the saturation pressure corresponding to the ambient temperature (i.e. absolute pressure of 0.008 MPa, which corresponds to 41.5°C). The goal of maintaining the lowest practical turbine exhaust pressure is a primary reason for including the condenser in a thermal power plant.
The pressure losses in the heat exchanger units of the boiler are estimated according to the following approximations: • Economizer: the pressure loss is 5-10 % of the pressure of the feedwater entering the economizer. • Evaporator: Once through boilers: in once-through boilers the pressure loss of the evaporator is between 5 and 30 %.
Working pressure in these boilers is in the range of 0.7 Mpa to 2 Mpa and efficiency of the boiler is about 65% - 70 %. Generally a chimney is used to provide the draught.
