WebFoaming is the production of persistent foam or bubbles in boilers, which do not break easily. Foaming is due to presence of substances like oils (which greatly reduce the surface tension of water). Priming and foaming, usually, occur together. They are objectionable because; (i) dissolved salts in boiler water are carried by the wet steam to ...
WebJul 22, 2024 · Priming 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. Priming may be caused by improper construction of boiler, excessive ratings, or sudden fluctuations in steam demand. WebUse of Anti-foaming agents such as castor oil. (Anti-foaming agents neutralize the effects of surface tension) Proper treatment of water before entry into the boiler in order to …
WebExcess of impurities, if present, in boiler feed water generally cause some boiler-problems like Scale and sludge formation, corrosion, priming and foaming, caustic embrittlement. I. Sludge and Scale Formation in Boilers: In a boiler, water is continuously evaporated to form steam. This increases the concentration of dissolved salts.
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. 3.
