Boiler (power generation) - Wikiped

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.

Common Boiler Problems, Part 2: Improper Blowdown Techniqu

Mar 09, 2018· The concentration of undesirable solids in a boiler is reduced through proper feedwater treatment and the proper operation of a continuous purge (blowdown) system, and by performing intermittent blowdowns on a regular basis. The sodium zeolite water softening process is the predominant method of water treatment for boilers operating at low pressures with saturated steam. In this ion …
