Boiler tubes are expanded and flared in low pressure boilers; expanded and beaded in high pressure boilers. Turbulator baffles are not used in tubes. Separate second and third pass rear tube sheets allow safe expansion and contraction. Waterbacked rear turnaround promotes rapid internal circulation and reduces gas temperatures at entrance to.

Nice stuff..!! It was very nicely explained the difference between two boiler methods with the example of apple and orange i. Mostly it depends upon the people for which they mostly prefer. I didn't know that watertube and firetube boilers worked in such opposite ways to get the same result. It sounds like firetube systems are a little more complex in their design, but it's interesting to see the advantages of each system. If I need to rent a boiler with easy maintenance, I'll go with a firetube. But if I need something that is more durable, I'll go with watertube.

The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them. Before moving to further detailed explanation lets have some overview of Fire tube and water tube boiler. Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download. A boiler is a closed vessel in which fluid generally water is heated up to high-pressure steam. The boilers are used in power plants, for the generation of steam. They are mostly used in power plants where steam turbines are used for the generation of electricity.

We know that boiler is used onboard for power generation and it is one of the most important thing on ship. Boiler is broadly categorized into water tube boiler and fire tube boiler. And since they are categorized differently this means that there must be some differences between them either in functioning, maintaining, running or economical differences. This article is all about their differences. In fire tube boiler, as the name suggest Fire Tube i. The heat transfer takes place between the hot gases and the surrounded water through the tubes. This heats up the water and convert it into steam.

When choosing a steam boiler for your facility, you typically have a choice between a water tube or a fire tube design. While both may have their advantages in certain situations, from an efficiency standpoint, Miura water tube boilers are far more efficient than fire tube boilers. Water turns to steam when it comes into contact with sufficient heat. From a design standpoint, water tube boilers and fire tube boilers have completely opposite approaches in how this contact happens. In a fire tube design, hot flue gas travels through tubes that are surrounded by the water.

Difference between water tube boiler and fire tube boiler in a descriptive format :

Boiler tubes are expanded and flared in low pressure boilers; expanded and beaded in high pressure boilers. Turbulator baffles are not used in tubes. Separate second and third pass rear tube sheets allow safe expansion and contraction. Waterbacked rear turnaround promotes rapid internal circulation and reduces gas temperatures at entrance to. The boiler system comprises of: a feed water system, steam system and fuel system.
