Water tube boiler has the advantage of safety, rapid heat transmission, and fast reaction to meet steam demand. On the other hand, it has a higher initial cost, is big in size, and more complicated to operate in comparison to the fire tube boiler. Examples of water tube boilers are Babcock and Wilcox boiler, Benson, Stirling boiler, etc.

Anyone who has ever boiled a pot of water for cooking knows how this process works. Making steam continuously, however, is a little more complicated. An important variable to measure and control in a continuous boiler is the level of water in the "steam drum" (the upper vessel in a water-tube boiler).

Steam boiler is kind of boiler where the water is heated inside tubes and the hot gasses surround them. A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi).
