    May 02, 2000 · The only way to control the cycles of concentration in boilers is to remove (blow down) some of the highly concentrated boiler water. Makeup water replaces blow down and dilutes the remaining boiler water. Blow down is performed two ways; bottom blow down and surface blow down. Ideally, blow down should be done in proportion with steam production.
