products. Refractory back boilers have only a single rear tube sheet that must work with the vastly different temperatures in a firetube boiler. The single rear tube sheet is subjected to the high thermal stresses of both the very high temperature (17000F to 19000F) first turn and a much cooler third turn (4500F to 6000F). Waterback boilers

Industrial Steam Process Products | Thermodyne Boilers

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

For the shell the width of that part of the circumference below the flue covers shall be taken as = 2 D, and this width + the length between end plates shall be taken as the area of shell heating surface. The part of the surface of the back-end plate exposed to heat shall be omitted from the calculation. Example.-.

How to calculate the heating surface area of a fire-tube

Jul 15, 2019 · PBoHP = boiler horsepower. A = heat transfer area (sq.ft.) Knowing the total heating area, then calculate the surface area of one tube; A = 3.1416 x tube diameter (inchs)/12 x tube length (ft) Divide this answer into the total heat transfer area and this will tell you how many tubes you need in the boiler…

Mar 12, 2012 · The fire tube boiler was created in the 1800s, Fig. 1.7.Its main use was to run steam engines for motive power. One of the first brand names for this type of boiler was the Lancashire boiler, which used two parallel fire tubes. It was used to power steamboats and railroad engines and to run industrial machinery via belt drives.

Calculator – Weight Per Foot. The ASTM calculation assumes that the tube is manufactured with a consistent wall thickness. The actual wall is always thicker than the specified minimum. The producing mills and R- S Matco, Inc. use the ASTM A-450 formula, but multiply the thickness by 1.10 for tubes with an OD less than 1-1/2" and 1.11 for 1
