how to calculate efficiency of fire tube 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.
