Maximum air-free concentration from gas kitchen ranges (ANSI). 1600 ppm. Headache, dizziness and nausea within 20 minutes. Death within 1 hour. Smoldering wood fires, malfunctioning furnaces, water heaters, and kitchen ranges typically produce concentrations exceeding 1,600 ppm. 3200 ppm.

Natural gas is nearly half the weight of air and rises to the ceiling or roof space of a boiler room. Natural gas is composed mainly of Methane – a combustible gas with a rapid expansion rate. In gas detection it is necessary to be aware of the potential hazard's LEL or LFL. LEL or LFL depending on your location stands for the Lower Explosion Level or Lower Flammable Limit. These values represent the minimum concentration …

Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2).

Measurement of Oxygen Concentration in Package Boiler Flue

Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas. The typical package boiler is a water tube boiler or flue and smoke tube boiler with a capacity of 5 to 20 t/h (average steam generation capacity). The most widely used fuels are heavy oil, light oil, kerosene, and gas.
