Incomplete combustion due to insufficient air yields an excess amount of:

  1. Carbon dioxide
  2. Carbon monoxide
  3. Nitrogen oxide
  4. Sulfur dioxide


And the correct answer is….


To ensure an adequate supply of air to the combustion zone, a number of factors need to be considered:

  • the amount of air required for the combustion process itself
  • the amount of air required for ventilation and cooling within the boiler room
  • the effect of the venting system, including such items as vent hoods, barometric dampers, economizers, and automatic draft control systems
  • the effect of heat transfer-enhancing turbulators
  • the presence of exhaust fans, either in the boiler-room or in any part of the building that may be a source of air for the boiler/burner or alternatively may draw air from the boiler room
  • the requirements of various codes and standards
  • the presence of any other equipment, fuel-burning or otherwise, that may potentially consume air required for combustion
  • the effect of altitude
  • boiler fire side and burner maintenance; and boiler room housekeeping.
