Foaming priming in boilers
WebWhen 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 This factor is by design. WebPriming is the carryover of varying amounts of droplets of water in the steam (foam and mist), which lowers the energy efficiency of the steam and leads to the deposit of salt crystals on the super heaters and in the turbines.
