The water is maintained at a certain level to prevent the tubes from getting too hot, and steam is allowed to escape through a narrow pipe. Maintaining the pressure inside the boiler was difficult and tragically, while the industrial revolution was at its height, explosions killed thousands of engineers each year.

Types of Marine Boilers and Difference Between Water Tube

On the other hand in water tube boilers, the water flows inside the tubes and the heat surrounds these tubes. Generally we use the water tube boiler in order to generate the super heated steam like on steam ships etc. the pressure generated on water tubes is always higher the smoke type of boilers.

The Differences Between Water Tube Boilers and Fire Tube

How A Water Tube Boiler Works. A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler.

Steam Boiler Water Level Monitoring: A History of

Reliable water level detection is vital to prevent damage to a plant and its personnel. Modern boilers are designed to provide clean dry steam and detection of incorrect water level in the drum. Too high a level can give wet steam, leading to turbine blade erosion and if the level is too low, the boiler tubes can overheat and risk explosion
