Difference Between Fire Tube Boiler and Water Tube Boiler
Apr 23, 2016 · Fire Tube Boiler. It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that’s why they fall under the category of low pressure boilers.

KEY COMPONENTS OF BOILERS | Boilers Guide
KEY COMPONENTS OF BOILERS. Boilers are part of a hydronic heating system. Hydronic systems use water to transfer heat to a distribution source, like a radiator, to heat a home. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed.
