On incrustation of marine boilers - ScienceDirect

In American men-of-war, where they seem to be able to afford more boiler space than in the British Navy, is often used a long circular returntube boiler' the tines being, of large diameter (say 1 ft. or more), with very ample water-spaces around and between them.

Feeding Boilers At The Bottom - ChestofBooks.com

This section is from "Scientific American Supplement". Also available from Amazon: Scientific American Reference Book . One of the most important things to be considered in boiler construction is the position and arrangement of the feed apparatus, but it is, unfortunately, one of the elements that is most often overlooked, or, if considered at all, only in a very superficial manner.

A Thermodynamic Theory of Circulation in Water-Tube Boilers - …

A thermodynamic evaluation is made of the work available for, and the resistance to circulation by, natural convection in a water-tube boiler. This leads to a theory of circulation which is independent of the usual type of hydraulic theory expressed in terms of density difference. The theoretical circulation equation is first used for the

Remaining life assessment for boiler tubes affected by combined effect …

Boilers, the most troublesome components of electric power, chemical and processing plants generate high costs in unscheduled shutdowns, repairs and power replacement. Every occurrence of ruptured tubes leads to emergency shutdown of the entire plant. This paper describes the joint international effort to develop faster and more efficient methods for condition assessment and remaining life
