In water tube boilers, the water is present inside the tubes and the fire or hot gases surrounds these water tubes. Examples of water tube boilers are: La-Mont boiler, Benson boiler, Stirling boiler, Babcock and Wilcox boiler, Yarrow boiler and Loeffler boiler .
Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.
Water tube boiler occupies a less floor area when compared to a fire-tube boiler that requires a large floor area. Water-tube boilers are lighter in weight and therefore transportation is also not tedious. Fire tube boilers on the contrary are heavy in weight and therefore they cause a lot of challenges to transport.
Fig.2.2.3 Schematic diagram of a marine type water tube boiler Coal-fired water tube boilers are classified into three major categories: stoker fired units, PC fired units and FBC boilers. Package water tube boilers come in three basic designs: A, D and O type
A fire-tube boiler works in the following way: First of all, a feed pump pumps water into the boiler. The grate is used to place the coal fuel. The fire is introduced into the furnace through a fire hole. As the fire ignites the fuel, the heat is produced. The produced heat transfers to the flue gases.
2021/5/26 · The Stirling boiler is a bent tube, externally fired, stationary water tube boiler with natural circulation. It has a pressure range of maximum 60 bar and a steam production of about 50000 kg/hr. Efficiency of Stirling boiler is up to 60% to 80%.
2009/7/29 · Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam
is the major by-product. In such cases dual fuel fired boiler is more effective from economic and environment point of view. 2. WORKING PRINCIPLE OF OIL & BF GAS FIRED WATER TUBE BOILER: The working principle of water tube boiler is
Page 3 of 34 2. Water tube boilers: Water tube boiler is a type of boiler in which water passes through the boiler where the tubes are placed in combustion chamber. They are Babcock & Wilcox boiler : Babcock and Wilcox, this type has a single drum, with feed
Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the firebox.
2020/4/12 · FIRE TUBE BOILER Hot flue gases flow inside tubes that are submerged in water within a shell. • Pressures up to about 10 bar • Produce up to 14 tonnes of steam/hr • Can meet wide and sudden load fluctuations because of large water volumes • …
