Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. 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
The boiler's job is to apply heat to water to create steam. There are two approaches: fire tube and water tube. A fire-tube boiler was more common in the 1800s. It consists of a tank of water perforated with pipes. The hot gases from a coal or wood fire run through the pipes to heat the water in the tank, as shown here:

Condensing boilers are up to 98% efficient. If you are replacing an aging boiler or building a new facility, installing a condensing boiler will improve your energy efficiency and reduce your operating costs. ZBG can provide fire tube and water tube condensing boilers that mainly fire natural gas, LPG, coal gas, light oil, heavy oil, diesel, etc.
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.

Water tube boilers. In the watertube boiler, the water is inside the tubes and gases of combustion go around the outside of the tubes. The advantages of a watertube boiler are a lower unit weight per pound of steam generated, less time required to raise steam pressure, a greater flexibility for responding to load changes, and a greater ability
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.
Generally speaking, water tube boilers can generate steam more rapidly. This is why steam automobiles shifted to monotube boilers as they developed, they could be up to full pressure in about a minute, give or take.
