Three Passes Within The Universal Pressure Boiler Furnace

2. BOILERS - Bureau of Energy Efficiency

Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler …

3 pass firetube boiler design - Industrial Boiler

The furnace represents the 1st pass through the boiler. Exhaust gasses from combustion then travel to the first reversal chamber. The gasses exit the reversal chamber and then enter the 2nd tube pass, second reversal chamber, 3rd tube pass, smokebox and finally the chimney. Water is heated by the heat from combustion and the resultant exhaust gasses.

Packaged Boiler, Three Pass Internal Furnace | Thermodyne

Watertube capacity with firetube efficiency. Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." A 3-pass firetube boiler design consists of three sets of horizontal tubes, with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.
