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.
Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.

Water and fire tube boilers 1. boiler 2. What is a boiler? Boiler is an apparatus to produce steam. Thermal energy released by combustion of fuel is used to make steam at the desired temperature and pressure.
Copper tube boilers are great for snowmelt applications. Lots of power in a small package. They like long steady burn times under fairly constant loads. Water quality is critical. Hard water can scale up the tube heat exchangers quickly, even the initial fill water. Check with manufactures for their water specs.
The water tube boilers are more suitable than the fire tube boilers for the generation of steam at very high pressures and also when the steam is to be raised quickly starting with cold water and fires out.

Why Water Tube Generate More Steam and Pressure Than Fire Tube Boiler 2016-09-05 16:18:22. A water tube boiler is the opposite of a fire tube boiler. Water flows through the tubes and that are incased in a furnace in which the burner fires into. The tubes are connected to a steam drum and a mud drum.
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time.
Boilers 291 Coagulation—a method for concentrating and removing suspended solids in boiler feedwater by adding chemicals to the water, which causes the impurities to cling together, p. 301. Condensate—condensed steam, which often is recycled back to the boiler, p. 294. Damper—a movable plate that regulates the flow of air or flue gases in boilers,
Water tube or “water in tube” boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum
