This is caused by calcium and magnesium in the boiler water. When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.
Locating a Water Heater Dip Tube. The water heater dip tube runs from the top of the tank to near the bottom. It is on the inside of the water tank so that you cannot see it. It is inserted into the tank at the cold water inlet. To see it you would have to shut down the tank and remove the cold water supply line.

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes.
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.
As well as from horizontal, vertical. And whether economic boiler is high pressure, or low pressure. There are 1,046 economic boiler suppliers, mainly located in Asia.
