Water Tube Boilers | Spirax Sarco
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.

Basics of hot water heating boilers - Specifying Engineer
2020/9/18 · All boilers require control of three basic elements to operate safely and efficiently: water flow, air flow and fuel flow. The heat exchange surfaces for hot water boilers must be in contact with water to prevent the heat exchange surface from overheating. Low level water sensors are required to ensure this.
