Carryover and its Causes - Leaders in Steam Engineering .

Fluctuating boiler loads increase the chances of carryover in boilers. When steam demand suddenly increases, the drum pressure drops down. As a result, the drum water will suddenly expand resulting in a phenomenon called ‘priming’. Due to priming, slugs of water will be carried along with the steam resulting in carryover. 3. Drum Size

A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.
