A boiler is an encased vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or a steam. The steam or hot water is then usable for transferring the heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gun powder. This is very good and efficient means for transferring heat for a process but it can also be extremely dangerous." Although they all pretty much work on the same principles, special attention needs to be added in checking out each individual boiler. The wrong valve opened or closed can be a disaster and a safety hazard.
The two most general types of boilers are hot water and steam boilers. Most small and large commercial buildings, manufacturers and business use hot water boilers. Water is heated to dispersing temperatures, typically 140-180F, and usually returned about 20F lower. These systems are called "closed loop", with minimal fresh water make-up. Hot water boilers are preferred because they normally do not need operators or major water chemistry. Since they operate at lower temperatures, hot water boilers can operate at higher fuel conversion efficiencies than steam boilers.
Steam boilers are used in many different applications, their one purpose: to use water and transform it into steam by heat. Some boilers heat the steam even hotter than the boiling point temperature. This is referred to as superheated steam.
