08/09/2020 · The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boilers basic principle is to convert water into steam with heat energy.
Exhaust Gas Boiler. The exhaust gas boiler and economizer are heat recovery units and types of water tube boiler. The flue gases from the exhaust of the engine are used to heat water in the tubes at a specific temperature and limited pressure loss. A circulation pump is used to continuously circulate the hot water in the water tubes of the economizer.
05/02/2015 · System boiler installation costs. A system boiler is just like a regular boiler, except that it doesn't need a large cold water feed tank for operation. For a guide price on system boiler installations, we would recommend looking at the regular boiler costs in the table above and adding £200-£400 to cover the additional costs of a system boiler.
29/10/2017 · The boilers are fitted with different safeties as the steam pressure is up to 8 bars in most cases. There are normally two kinds of boilers on ships, Auxiliary and Exhaust, some ships have composite boilers. Boiler are of two type. STB (Smoke tube Boiler) or donkey boiler; WTB (Water tube Boiler) or High pressure boiler

09/12/2015 · An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum as well as the steam space. The tubes consist of a large number of smoke tubes and a small number of stay tubes. The stay tubes with an increased diameter act as support for the boiler. Both types are welded onto the lower
It is the responsibility of the Chief Engineer to ensure that all members of the Engine room Staff are familiar with the procedures for the safe operation and maintenance of the exhaust gas boiler/economisers. Principles of safe operation, such as ensuring that valves and mountings are operational and correctly set, and the necessity to warm through and cool down in a gradual manner
