The Effects of Carryover in Steam Boiler Systems

It is often possible to add a treatment chemical to boiler water that will counteract foaming. These chemicals, called antifoams, can control carryover to a tolerable level without increased blowdown or additional external treatment. Their use can even reduce fuel consumption by permitting lower blowdown rates while maintaining high purity steam.
