They are one of the two common boiler designs commonly employed today, the other design being the water tube boiler. The boiler shown in this video is a three pass boiler, as the gasses pass three times through the boiler shell. How Fire Tube Boilers Work Fuel is fed by a burner into a corrugated furnace along with air. The air and fuel mix and a source of ignition is applied in order to start combustion. The heat from the flame and exhaust gases is passed to the corrugated furnace, then to the water due to thermal conduction. The exhaust gases then pass through a reversal chamber, the second pass of tubes, the third pass of tubes, then finally through a smoke box and out of the chimney. The furnace and tubes allow the heat generated by combustion to be transferred to the water in the shell. As the water in the shell is heated, it begins to turn to steam. Fire tube boilers rely upon on relatively few parts, these parts include: * Shell – fired pressure vessel. * Burner – used for combustion. * Corrugated Furnace – where combustion occurs. * Tubes – used to direct exhaust gasses through the shell. * Tube Sheets – used to hold the tubes in position. * Reversal Chamber – gasses are reversed in this space and sent back in the opposite direction. * Cover – retains insulation which increases the thermal efficiency of the boiler. * Smoke Box – located where exhaust gasses exit the final tube pass, but before the chimney.
