Marine Steam Boilers: Fourth Edition deals with the involved concepts, parts and construction, usage and maintenance, and the future direction of steam boilers. The book covers topics such as the history of steam boilers; theoretical development of steam boilers; and the materials and methods used in their construction. Also covered are the types of boilers - the tank-type boiler, which includes horizontal and vertical boilers; water tube boilers such as the Foster Wheeler boiler, Babcock & Wilcox boilers, and combustion engineering boilers; and dual-fired boilers. The text is recommended for marine engineers who would like to know more about boilers, its different types and the advantages of each, and their operation. Table of Contents.

A monotube boiler, a type of steam generator (early 1900s ) A steam generator is a form of low water-content, similar to a boiler. The usual construction is as a spiral coil of, arranged as a single, or, coil.

Circulation is once-through and pumped under pressure, as a. The narrow-tube construction, without any large-diameter drums or tanks, means that they are safe from the effects of, even if worked at high pressures. The pump flowrate is adjustable, according to the quantity of steam required at that time.

The burner output is throttled to maintain a constant. The burner output required varies according to the quantity of water being evaporated: this can be either adjusted by according to the pump throughput, or by a to maintain the measured temperature. They are used as on ships. Contents • • • • • Types [ ] Stone-Vapor [ ] One of the best-known designs is the Stone-Vapor.

The inner casing of the boiler forms a vertical bell, with an outer airtight cylindrical casing. The oil or gas burner is mounted at the top, above the coils, and facing downwards. The heating element is a single tube, arranged into a number of cylinders. The first helices (in the flow direction) are small-diameter tubes, wrapped in large diameter turns. Succeeding turns are coiled inside this and the tube is of progressively increasing diameter, to allow for a constant flow rate as the water evaporates into steam and forms bubbles. The steam outlet is from the final turn at the bottom of the inner helix.

The outlet is approximately 90% steam (by mass) and residual water is separated by passing it through a. The exhaust gases turn upwards and flow over the outside of the bell, usually passing additional helices that are used as an initial. Clayton [ ] The Clayton steam generator is similar to the Stone-Vapor, but the burner and flow directions are reversed. The heating coil is mounted within a simple cylindrical casing.

Rather than helical, cylindrical layers, the Clayton coils are arranged as layers of flat. Water is pumped into the top layers and forced downwards.

Again, the tube diameter increases in steps, as evaporation takes place. The final turns form a single closely spaced helical cylinder around the burner as a and is heated by radiant heat. The steam output is passed through a centrifugal separator and a dry steam quality of 99.5% is claimed.

Firstly, small diameter tubes are inherently stronger than large tubes of the same construction, as was first appreciated by in the mid-19th century. Secondly, the low water-content means that there is relatively little volume of water per area of heating surface (i.e. Boiler power). As the destructive energy of a boiler explosion is largely due to the sudden release of this energy, and proportional to water volume, a low water-content boiler has a more favourable ratio of useful power (from its area) to risk (from its volume).
