The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
In general, condensing boilers are identified by their internal construction as either fire-tube or water-tube boiler designs, as illustrated in Fig. 2 below. A fire-tube, as the name suggests, has the hot flue gases from the combustion chamber, passing through the tubes and out the boiler vent. These tubes are surrounded by a water jacket.
Additionally, since the tube holds less water than the water tank of a fire tube design, it takes less time to turn that water to steam — and by extension, less fuel. A water tube boiler produces steam in as little as five minutes, compared to an hour or more for fire tube boilers. As a result, fuel savings costs can be significant over time.
Fire Tube Boiler: The fire tube boiler is a kind of industrial boiler that the flue gas generated after fuel combustion flows through the fire drum or flue pipe to heat the water, steam or steam-water mixture outside the fire drum or flue pipe. It is also called a shell type boiler. Advantages: 1. It has a simple structure, easy operation, and
3. Scotch Fire Tube Boiler Design. The scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located inside of the boiler. The furnace and boiler are circumferenced by water. Some of the larger, older scotch boilers would have two or even three different
Water Tube Boilers. Unlike fire tube boiler, where the hot gas is circulated through tubes to heat water in a tank, water tube boilers involve running water through tubes surrounded by a heated tank. These types of boiler are generally considered safer than fire tube designs and typically require less frequent maintenance. They also can be
Water tube steam boiler. HoSt supplies water tube steam boilers. In a water tube steam boiler water flows through the pipes and the flue gasses pass around the pipes. Water tube steam boilers are applied above 32 bar and with difficult fuels. This type of boiler can be cleaned automatically and with ease.
The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
2020-3-14 · The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler.. Water-tube boiler: The 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 firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the two:
2020-3-10 · The distinction between fire tube boiler and water tube boiler should be possible on different focuses. These focuses incorporates sorts of liquid streams inside the cylinders, steam age rate, floor zone required for the steam age, transportation, proficiency, fluctuating burdens, working expense and so forth the learning of the distinction about these two heater is exceptionally critical.
