Firetube vs Watertube Boilers: a Comparison

Feb 19, 2015· The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes … The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the two:

Choosing The Right Boiler: Watertube vs. Firetube - Boiler

Each boiler pass should be designed with a cross sectional area to … not need high maintenance, boiler tube, add-on devices if the boiler is designed for optimum flue gas velocities in the first place. Each boiler pass should be designed with a cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing soot build-up within the tubes.File Size: 296KB

Why Water Tube Boilers Are More Efficient Than Fire Tube

Water turns to steam when it comes into contact with sufficient heat. From a design standpoint, water tube boilers and fire tube boilers have completely opposite approaches in how this contact … Water turns to steam when it comes into contact with sufficient heat. From a design standpoint, water tube boilers and fire tube boilers have completely opposite approaches in how this contact happens. In a fire tube design, hot flue gas travels through tubes that are surrounded by the water. In a water tube design, the opposite applies — the water heats by traveling through a tube surrounded by flue gas.
