To go from 212F water to low pressure steam requires another 970 BTUs per pound. Increasing the pressure increases the temperature of the phase change, and increases the amount of energy the water/steam can carry. At pressures higher than atmospheric, more heat must be added to water (sensible heat) before it can turn to steam.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

6. The pressure before the economizer can be calculated by adding the pressure loss in the economizer to the feedwater pressure after economizer. The feedwater temperature might be stated in the boiler design assignment. If it is not given, it should be chosen from the range of 200-250 °C.

Steam Boiler: Hydrostatic Test in Steam Boiler

The heat in the steam produced is about 95% of that lost by the gases passing through the boiler. Heat lost by hot gases =Vs(t 1 − t 2)MJs − 1, where V = m 3 gas/sec, s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs (t1 − t2)MJ s −1, t1 and t2 = temperature of hot gases before and after the W.H. boiler, °C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t2, the temperature at which the flue gases leave the boiler, may be reduced to ca. 50 K above the temperature of the water in the boiler.

A boiler is a pressure vessel that is designed to generate heat, produce steam or cool gases. Typically built as a rectangular or cylindrical tube, the vessel is closed at both ends and is fully insulated. Fuels such as wood, coal, oil, or natural gas power the device, making it possible for pressures of 30 bar and more to be created inside.
