Three Pass Firetube BoilersFiretube boiler designs can vary significantly. Various tube and furnace arrangements have been developed to maximize boiler efficiency and pressure vessel longevity. One of the primary variations occurs in the arrangement of the firetubes. Designs are available to provide for 2, 3, or 4 gas passes. Furnaces can be located high or low within the boiler shell. Boilers are available as dry back or wet back (water cooled gas reversal area). The popular Cleaver-Brooks design includes 3 or 4 gas passes with a low furnace location for optimum thermal efficiency (see Figures 1-1, 1-9), and dry back or wet back arrangement.
