Water tube boiler and fire tube boiler in Vietnam

Recently, a client from Vietnam consulted a water pipe boiler and a water pipe boiler. So, what's the difference between the two boilers?

Fire tube boilers

In a fire tube or shell boiler, the hot combustion gases produced by the burner are passed through small tubes arranged in a pressurised cylindrical drum and surrounded by water. Heat energy is transferred to the water which is heated up until it becomes steam. Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.

Water tube boilers

Industrial water-tube boilers work in the opposite way: water is circulated inside the boiler tubes and the tubes are surrounded by hot gases. This type is relatively rare in the UK, but much more common in other parts of the world. Due to the small tube diameter, a water tube boiler can operate at much higher pressures than a fire tube boiler, so they are often used in power station applications that require a high steam output, high pressure steam or superheated steam.
