Combustion Testing Procedures

While stack draft may be an important measurement, fuel oil and gas fired power burners require draft control over the fire to maintain a proper and controlled intake of combustion air. Comparing stack and overfire O 2 can verify that leakage between boiler sections, access door, etc is minimal and the combustion test results are accurate.
