The first trials and explosions started in the late 1700's and the first patented boiler was not until 1867. Steam boilers brought about the industrial revolution by providing room/building heat, building materials (lumber from saw mills), trains, ships and many other uses. Today healthcare, educational and institutional facilities use steam for building heat, domestic hot water, and humidification where desired. Effective water treatment and operation can help not only optimize operating costs and increase reliability of the boilers themselves but also the steam network as a whole.Steam Boilers: The Truth or Consequences< /br>Dan Weimar, Dr.Eng, Member, Chem-Aqua, Inc., Irving, TXProtecting Your Steam Network< /br>Henry Becker, Earthwise Environmental, Chicago, ILSteam Boiler Pre-Treatment: It’s Not Just Chemicals!< /br>Joseph Ham, Member, DuBois Chemicals, Sharonville, OH
