    Deposits of a porous nature allow boiler water to permeate the deposits, causing a continuous buildup of boiler water solids between the metal and the deposits. Because caustic soda does not crystallize under such circumstances, caustic concentration in the trapped liquid can reach 10,000 ppm or more.Learn More

  • Common Boiler Water Problems - Water Treatment Services

    1. Scale Build Up. Poor water quality can severely damage your boiler system. Minerals, like calcium and others, in the water can accumulate in the boiler and pipes as scale deposits. These deposits can slow the passage of steam through the system or block it entirely.Learn More

  • Boiler Water Treatment | Sensors for Process Control

    Conductivity control is important for minimizing the mineral level in the boiler by replacing process water with fresh water. This removal of water is referred to as blowdown. While blowdown is an important process, excessive blowdown should be prevented to avoid wasting water and energy.Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Solutions: To prevent reoccurrence of caustic gouging, operators should prevent accumulation of excessive deposits and control water chemistry so that boiler water does not locally form caustic in areas where chemicals concentrate. In some instances, where caustic gouging along the top of a sloped tube is associated with steam-water separation Learn More

  • Water Handbook - Boiler Fireside Deposit and Corrosion

    Boiler water chemical treatment is necessary to prevent or control scale and deposit formation. The formation of deposits and scale can cause tube failures, restrict circulation, reduce system efficiency and compromise your boiler system's reliability.
