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 …
TUBE *BOILERS This manual, originally entitled "All About Deliming Coil Type Water Heaters," was prepared as a maintenance instruction for deliming A.O. Smith Burkay copper coil boilers. *This manual has been revised to include Light Lime Deposit Removal instructions for other A. O. Smith copper tube boilers such as DuraMax, Genesis and Legend.
In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.

In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.
