Difference Between Fire Tube Boiler and Water Tube

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.
