Boiler Types - There are many different types of boilers in the boiler room today in a variety of heating applications. There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers.Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers).

2010-8-3 · The final separation of moisture in the steam is accomplished as the steam comes into contact with the W-shaped Chevron elements forming the drier assemblies. Steam enters the driers at a low velocity and makes several abrupt changes in flow direction. This causes the entrained moisture to adhere to the large surface area presented by the Chevrons.
