Most Common Steam Boiler Types | Miura America

Fire Tube Boiler. The most common type of boiler system especially for industrial uses, fire tube boilers, has been around for a long time because of their ability to meet steam needs when the demand is large and constant. These pressure vessels are filled with water, and the fuel used to heat the water is kept inside a series of tubes.

How a Water Tube Boiler Works | Miura America

Jul 25, 2017 · Economizer (heat exchanger) is the boiler accessory used to recover the heat of flue gas that leaving the boiler by heating feed water. The efficiency of a boiler can be increased with an economizer. 60C rise in feed water temperature with the help of economizer can save up to 1% of fuel.

Water Tube Boiler | Operation and Types of Water Tube

Aug 28, 2019 · Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.
