A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
Learn MoreIn watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.
Learn MoreIn contrast to its internal construction, which includes a small steam drum and small diameter tubes, the water tube boiler is used to generate steam having high pressure and temperature. These small internal parts produce high volume steam for high capacity applications. Water tube boilers are the most widely used boilers.
Learn MoreIn a water-tube boiler ('''Figure 3'''), the water is inside the tubes and combustion gases pass around the outside of the tubes. The advantages of a water-tube boiler are a lower unit weight-per-pound of steam generated, less time required to raise steam pressure, a greater flexibility for responding to load changes, and a greater ability to
Learn MoreMay 30, 2018 · 1. Refineries use Water tube boiler more than Fire tube boilers. 2. Reboilers (Kettle type boilers) are heat exchangers typically used to provide heat to the bottom of industrial distillation columns.
Learn MoreJun 24, 2014 · If you're using the boiler during the summer to make domestic hot water, you won't be able to drain it, of course, so you'll have to deal with the dirty water. The installer didn't clean the boiler. Boiler manufacturers use a lot of oil when they drill and tap the boiler. The installer also uses oil when he threads his pipes.
Learn MoreHow Water Tube Type Steam Boilers Work. One of the latest advances in steam boiler technology is the use of water tube boilers. This type of boiler is distinct from conventional fire tube boilers. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel. They are also much safer than fire tube
Learn MoreNov 19, 2013 · A water-tube design is the exact opposite of a fire tube. Here, the water is inside the tubes and the combustion gases pass around the outside of the tubes. Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a feedwater inlet line
Learn MoreJul 19, 2012 · In water a lot of impurities are present when we use such water it will produce slice formation inside the tube of boiler due to which there is slice formation takes place and heat will not
Learn MoreAug 19, 2019 · A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor. The water may need filtering to operate most effectively.
Learn MoreBoiler expanders are designed with rolls sufficiently long to roll 1/4 to 3/8 beyond the sheet thickness. Boiler inspectors insist that tubes be rolled the full thickness plus a minimum of 3/16 beyond the sheet or drum thickness to a maximum 1/2. Its very common to use four or five different tools when repair water-tube boilers.

Learn MoreWater passes through boiler tubes while the combustion gases remain on the shell side, passing over the tube surfaces. II Applications Water tube boilers are most commonly used where high steam pressures are required and can exceed 3,000 psig. Water tube boilers can generate saturated or superheated steam, which is useful for applications such
Learn MoreThe different types of boilers find their use in different applications. As the time has passed, more efficient types of boilers have replaced the old and inefficient ones. This article elaborates on different types of boilers and the boiler classification. Boilers can be broadly classified as shell tube and water tube boilers.
Learn MoreThe water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes. The examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
