Boiler (power generation) - Wikipedia

2019-10-13 · 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.

Steam generation fundamentals - EnggCyclopedia

High pressure steam generation. The point where water turns into steam depends on the water flow rate (boiler load) and heat input rate. With close control of both flow rate and heat input rate, we can make sure that all of the water is evaporated withing the tube and only steam leaves the tube. Therefore, there is no need for having a
