  • Boiler Project Fundamentals - AIChE

    A steam boiler is used to heat water into steam, and the steam is circulated through a closed-loop piping system to transfer heat and/or humidity to a process. If you have processes that require different steam pressures and tempera-tures within your system, you can use pressure reducers to modify the pressure of the steam for specific pieces Learn More

  • Chemical Treatment for Steam Boilers | Miura America

    Alkalinity is used to "boast" the boiler water pH. This decreases the overall corrosion rates. Phosphates and polymer are used to keep the calcium in solution and keep scaling from developing in the boiler. Amines are used to "boast' the condensate, thus reducing the over all steam system corrosion rates.Learn More

  • Steam Boiler Guide for Chemical Processing Plants | Miura

    The main ingredient of Miura's BOILERMATE® is silica, a corrosion inhibitor. Silica is a naturally-occurring material ideal for water treatment in Miura's once-through boilers. Years of research and experience have shown that watertube corrosion can be controlled by balancing the amount of silicate in the water and corrosive ions.Learn More

  • The Importance of Boiler Water and Steam Chemistry

    For drum boilers operating up to 2000 psig (13.8 MPa), most nonvolatile chemicals and impurities in the steam are carried by small water droplets entrained in the separated steam. Because these droplets contain dissolved solids in the same concentration as the boiler water, the amount of impurities in steam contributed by this mechanical Learn More
