What is a boiler? A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.

A "Scotch" marine boiler is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smok
The most common firetube type is the scotch marine firetube boiler, which utilizes a large furnace tube and many smaller boiler tubes. The hot gases from the combustion process pass through the tubes transferring the heat to the surrounding water. This process develops the high temperature required to boil the water and begin the steaming process.
Marine Engineering The maritime industry is a rapidly changing one and marine engineering is an integral part of it. Marine engineers working in the industry have to keep themselves abreast with the latest developments and regulations.
Fuel oil burning process - various design burners ; Marine boilers currently burn residual low-grade fuels. This fuel isstored in double-bottom tanks from which it is drawn by a transfer pump up to settling tanks. Here any water in the fuel may settle out and be drained away. Boiler arrangement - combustion process - supply of air
