Water tube boilers can operate at pressures up to 5000 psig. Additionally, when used with steam circulating super-heaters, they are capable of reaching much higher temperatures than fire tube boilers. For these reasons, water tube boilers have become the …

What is a Fire tube boiler? The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes.Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.

2020-5-8 · 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 examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.

Fire tube boilers (also known as shell boilers) and water tube boilers are two main types of industrial boilers. Users select fire tube boilers and water tube boilers for specific applications. To purchase an appropriate boiler type is not an easy task because it is hard to say which type of boiler is better.

In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2: These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers. 3

Fire Tube Boiler. It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that’s why they fall under the category of low pressure boilers.

Fire tube boiler have lower rate of steam production compare to water tube. It has higher rate of steam production. These boilers are almost internally fired. Furnace is placed at the one end of fire tube. These boilers are generally externally fired. It is suitable for the production work like sugar mill, textile industries.
