Scale And Sludge In Steam Boiler Related Information

  • scale and sludge formation in boilers

    Scale and sludge formation in boilers. In boilers, water evaporates continuously and the concentration of the dissolved salts increases progressively. When their concentrations reach saturation point, they are thrown out of water in the form of precipitates on the inner walls of the boiler. If the precipitation takes place in the form of loose and slimy precipitate, it is called sludge.Learn More
