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.

Glossary of boiler terms - Wikipedia

Glossary of boiler terms. Periodic venting of water from the boiler. This water contains the most concentrated precursors for sludge build-up, so by venting it whilst still dissolved, the build-up is reduced. When early marine boilers were fed with salt water, they would be blown-down several times an hour.
