Boiler carryover
WebFluctuating 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. ...
