Fire-tube boiler

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low ...

Steam Boiler vs Hot Water Boiler

10/12/2016 · In contrast, a hot water boiler will typically require an expansion tank, a circulator, and a flow check valve. Most importantly, a hot water boiler will require a motorized pump. Cost of Implementation. The cost associated with steam boiler vs hot water boilers are approximately the same.

Water Tube Boiler - Definition, Components, Working

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. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Boilers

tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure obtainable is limited by their large shells to about 300 psi. Fire-tube boilers are used for heating systems.

around 11/4 to 13/4 pounds of stored water for t every pound of steam per hour for which the boiler is rated. This water content is a function of the convection tube spacing which dictates the boiler pressure vessel diameter. It is also related to one of the design standards that has developed over time for firetube boilers. That design

2. BOILERS - Bureau of Energy Efficiency

Water tube or “water in tube” boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum type. These boilers can be built to any steam capacities and pressures, and have higher efficiencies than fire ...

STUDY ON BOILER

For example, steam locomotives have fire-tube boilers, where the fire is inside the tube and the water on the outside. These usually take the form of a set of straight tubes passing through the boiler through which hot gas flows. In a cast iron sectional boiler, sometimes called a "pork chop boiler" the water is contained inside cast iron sections.
