The 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.
• If loss of water flow occurs from pumps and the tubes go dry they will overheat quickly and may rupture causing a release of high pressure steam that could damage the boiler. Most boilers have oxygen monitors in the firebox and also in other areas of the boiler.
1 Boiler is Water Tube Boiler and another one is Fire Tube Boiler. We need to replace the Tube bundles of both the above Boilers. Can any one suggest the thumb rule in costing and the difference in costing for both WT as well as FT Boiler. Same MOC of Tubes, Tube Sheets can be assumed for both the Boilers.
The fire tube boiler was created in the 1800s, Fig. 1.7.Its main use was to run steam engines for motive power. One of the first brand names for this type of boiler was the Lancashire boiler, which used two parallel fire tubes. It was used to power steamboats and railroad engines and to run industrial machinery via belt drives.
Difference Between a Heater, Furnace, and Boiler In the middle of this frigid winter, you may wonder what device is causing your living room to maintain that comfortable 72 degree temperature. Most homes are equipped with a central heating system, though the parts that make up that heating system can be a bit confusing.
In fire tube boiler the fire or hot gas are present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water. The examples of the fire tube boiler are: simple vertical boiler, Cochran boiler
Understanding the operational design differences. Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved.
