Water Handbook - Once-Through Cooling | SU

2  · In untreated once-through cooling systems, the metal loss may reach 100 mils (0.1 in.) per year. Treatment typically reduces the corrosion to 10 mils (0.01 in.) or less per year. In addition to metal loss, deposit problems are caused by corrosion product accumulation in a heat exchanger tube exposed to an untreated stream of cooling water.

Boiler Blowdo

Boiler Blowdown of steam boilers is often neglected or abused. The purpose of boiler blowdown is to control solids in the boiler water. Boiler Blowdown protects boiler surfaces from scaling and/or corrosion problems. Even if you are using a good steam boiler water treatment program, you will still be required to have some form of boiler blowdown.
