Numerical Investigation of Heat Transfer in 4-Pass Fire

Clean Firetube Boiler Waterside Heat Transfer Surfaces The prevention of scale formation in firetube boilers can result in substantial energy savings. Scale deposits occur when calcium, magnesium, and silica, commonly found in most water supplies, react to form a continuous layer of material on the waterside of the boiler heat exchange tubes.

Meet The Turbulator | Fuel Efficiency, LLC.

Tube wall temperatures, fluid bulk temperatures, and flow rates were measured to derive sectional average heat transfer coefficients for four segments of the tube. Reference data for the empty tube were in agreement with the usual correlations. Eleven different geometrical variations of one type of bent-strip insert were tested.

Clean Firetube Boiler Waterside Heat Transfer Surfaces

Mar 12, 2012 · Fire tube boilers are large-volume boilers. A large vessel, filled with water, is pierced with tubes of various sizes. Radiative heat transfer occurs mainly in the fire tube at the bottom. Convective heat transfer takes place in the large number of parallel gas tubes in the top. Hot flue gas transfers heat through tubes to the water.

So, performance of any boiler not solely but mainly depends on the efficiency of the heat transfer. Metals are good conductors of heat. Hence, all the contact surfaces between fire side and steam side are metals or metal alloys. In continuous operation of a boiler, it becomes quite difficult to maintain the metal tube surfaces clean, without
