Proper Boiler Blowdown Procedure | Cleaning Steam Boilers

Only pure water leaves the boiler as steam is produced; any dissolved solids are left behind. Even though the condensate is pumped back into the boiler, some is inevitably lost and must be replaced with make-up water. Over time, the concentration of dissolved solids from the make-up water increases in the boiler as pure water is removed as 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.
