Clean Firetube Boiler Waterside Heat Transfer Surfaces The prevention of scale formation in firetube boilers can result in substantial energy savings. Scale deposits occur when calcium, magnesium, and silica, commonly found in most water supplies, react to form a continuous layer of material on the waterside of the boiler heat exchange 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.

The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.
water tubes of the absorption-chamber A. These couples were cali brated in air, and in flowing water before installation, and the calibration was checked after assembly in the tubes. The thermocouple leads, insulated with silk and two coats of varnish, are carried out through a glass tube to the rear of the supporting pipe, P. 3.
Water-tube boilers are best suited to relatively high pressure operation (>40 bar) and have good response to changes in load demand. Tubing is arranged to suit the type of heating fluid, its temperature and pressure, and heat transfer characteristics coupled with the operating conditions of the boiler water.
Steam/water diagrams used in boiler calculations Temperature-heat (T-Q) diagram The T-Q diagram is a useful tool for designing heat exchangers. It can also be used to present the heat transfer characteristics of an existing heat exchanger or heat exchanger network.
A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded b
