May 04, 2017· Water Tube Boiler: * Water circulates in tubes and heated externally by hot gases. Fuel is burned inside the furnace. i.e (hot gases- outside the tubes and water- inside the tubes). * Operating pressure = upto 100 bar * Efficiency = upto 90% * Ste

Apr 23, 2016· 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.

The main difference between the two designs is an obvious one; they are complete opposites in terms of the location of the water relative to the hot gases. Therefore the direction of heat transfer will differ in each design (as shown in Fig. 3), where we will eventually see, can have a direct impact on the boiler …

Difference Between Fire Tube Boiler And Water Tube Boiler 06-28 17:30:04 What is a water tube boiler or fire tube boiler. A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly

Jun 05, 2018· Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.

Mar 19, 2016· 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 …

There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion

This article discusses about the different parts or components that are present in a boiler. In this article we will get to know about each every component that is fitted inside the boiler. For example, super heater is the part of boiler that is used to generate superheated steam. Let’s discuss these parts in detail.

They required a large shell diameter. Because the firetube situated inside the shell. They required a small shell diameter. 13. The efficiency of the fire tube boiler is less as compared to the water tube boiler. The efficiency of the water tube boiler is more. 14. The maintenance of this boiler is costly. It requires regular inspection.

produce. Firetube boilers are rated in boiler horse power (BHP or HP). To translate between these two languages you need to know only one formula, one (1) BHP is equal to 34.5 pph of steam from and at 2120F. 1 BHP = 34.5 pph Formula I WATERTUBE BOILERS Watertube boilers are available in …

This fundamental difference between the two types of boilers is directly related to the amount of water they use. In fire tube boilers, if the metal were to shrink as a result of the water level getting too low, additional cold water being fed into the boiler would cause the metal to expand too quickly, resulting in an explosion that could be

Mar 04, 2020· A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which

Firetube boilers have easy access to the boiler’s firesides and tubes can easily be replaced without additional repair of the boiler. Although firetube boilers are smaller in design, they have a larger water volume than similar size watertube boilers, causing them to take longer to bring up to operating temperature from a cold start.

The difference between a hot water and a steam boiler is in the design of the _____ heat exchanger/combustion chamber a watertube boiler has the ability to follow load swings _____ and generally has better turndown than a firetube boiler. more precisely

Jun 13, 2013· However, from a manufacturing standpoint, firetube boilers are typically lower in cost than a comparable sized watertube boiler, the firesides are easier to clean, and the straight firetubes are easily replaceable. Let’s not forget that there is a tremendous difference in water volume between a firetube boiler and a watertube boiler.

The main difference between firetube boilers and watertube boilers is explained by their names. In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water.
