WebAug 14, 2024 · Oil, grease, or other organic contaminants can also cause carryover due to foaming. The alkalinity in boiler water can react with these contaminants to produce a crude soap that causes foaming and carryover. Selective vaporous carryover occurs due to the solvent properties of steam. 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.
