Boiler Efficiency and Combustion | Spirax Sarco

A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to the plant, and is simply on stand-by.

Locomotive Boiler: Definition, Parts, Working Principle, …

Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be identified by the shape of the tube configuration, with the common types being called A, O, and D style boilers. The cast iron sectional boiler is neither fire tube nor water tube though it has some operating characteristics of a water tube boiler. The water is inside the sections and the fire is outside the sections. Cast iron sectionals used for steam heating may have distinct operating problems that are not typically found in other boiler types, such as the intolerance for poor water chemistry. • A boiler …
