In this article, we look at the construction and operation of the marine boilers found on both steam-powered and fuel oil powered ships. The steam generation process is explained and important key phrases are defined. The various uses for steam aboard ship are described, and the difference between the water tube and fire tube basic designs in explained. Learn about how marine boilers work and
function, location and working of mountings and accessories. A) SAFETY VALVE: The function of the safety valve is to permit the steam in the boiler to escape to atmosp0here when pressure in the steam space in the boiler.
Single tube steam boilers have only one fire tube or water tube. Simple vertical boiler and Cornish boilers are single tube boilers. Multi Tubular Boiler. In a multi-tubular steam boiler, there are two or more fire tubes or water tubes. Stationary Boiler. These boilers are mainly used in power plants, and in industrial process work.
Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.
If using non-modulating boilers, it may be better to stage subsequent boilers on once the primary boiler has reached full capacity, rather than cycling multiple boilers on and off to meet the load. On the other hand, with modulating boilers, boiler efficiency increases at part load conditions.
A steam drum is a pressure chamber of a steam boiler located at the upper extremity of steam boiler circulatory system. It is a reservoir of water/steam at the top end of the water tubes. The steam drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.Steam is separated from the water and then discharged at a position above the water level
Evaporator is one of HRSG components which serve to convert water into saturated steam. Evaporator pipes in steam boiler are usually located on the floor (water floor) and also on the wall (water wall). In this pipes, quality of saturated steam at 0.80 to 0.98, so most are still shaped in liquid phase.
