Water Tube Boiler - Types, Working, Construction

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.

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Meaning if the pressure drops on a fire tube boiler, it takes longer to come back up than on a similarly rated water tube boiler. Fire tube boilers typically have lower operating and maintenance costs, have easier access to the fire and water sides for inspections, and its much easier to replace tubes on a fire tube than a water tube.

Introduction to Hot Water Boilers and Hydronic Systems

An electric-powered circulator sends the hot water to and from your boiler. This is why some people call boilers forced hot-water systems, in contract with a furnace which is referred to as a forced warm-air system. Fire Tubes. Boilers are commonly made from steel or cast-iron, and use "fire tubes" which carry hot combustion gases.
