Difference between Fire Tube Boiler and Water Tube Boiler

Mar 19, 2016 · The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.

Fire-tube boiler - Wikipedia

The earliest form of fire-tube boiler was Richard Trevithick 's "high-pressure" Cornish boiler. This is a long horizontal cylinder with a single large flue containing the fire. The fire itself was on an iron grating placed across this flue, with a shallow ashpan beneath to collect the non-combustible residue.

How a Pressurestat Works

That is the number of degrees between when the pressurestat turns on and when it turns off. If too large there will be a wide range of temperatures reached in the boiler and brew quality will be compromised. If too narrow, the heating element will go on and off too often and the electrical contacts inside the pressurestat will not last very long.

Water-tube or fire-tube condensing boiler, which is the

In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.
