It may be caused by impurities in the water, which foams up as it boils, or simply too high a water level. WebTwo of the most common mechanical causes of carryover are operation in excess of design load and sudden increases in load. Foaming is one of the mechanisms of chemical carryover. Foaming tendencies are increased with increases in alkalinity and solids content. Stable foam bubbles contain boiler solids and are carried forward with the steam ...
