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.

Boiler Safety

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat.

"Operate the boiler at its maximum design pressure" is a common saying among boiler designers. But too often, this rule is not followed when energy cost reductions are needed. During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure.

Pressure Steam - an overview | ScienceDirect Topics

Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of increase in efficiency with increase in pressure becomes less as the pressure increases. A limit to the practicable operating pressure is set by the difficulty in separating moisture from steam in the boiler drum.
