Industrial boilers are closed vessels that use a fuel source or electricity to heat water or generate steam for industrial heating and humidification applications. The basic concept of a boiler involves a heat source (furnace) and a heat exchanger (pipes or tubes) or heat transfer medium which allows water to be heated above its boiling point.
