    The air density will change in direct relationship to the (absolute) air temperature, as defined by the "Ideal Gas Law". In other words, if the air temperature increased from 60°F to 100°F, the air density would decrease from .0765 lb/cf to 0.071 lb/cf, which is a 7.2% decrease in density. The fan is a constant volume device (Fan Laws).Learn More

  • Boiler/Burner Combustion Air Supply Requirements and

    As a "rule of thumb," 1 ft 3 of natural gas theoretically requires 10 ft 3 of air for complete combustion at 60°F and 14.7 psi under perfect conditions. Of course, this never happens, therefore burner combustion air fans may be sized for 25% excess air, in which case the fan would deliver 12.5 ft 3 of air per 1 ft 3 of natural gas. Additionally, many burner manufacturers will size the combustion air fans to provide …Learn More

  • Technical advice on boiler combustion control

    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).Learn More

  • THE EFFECT OF AMBIENT AIR AND WATER TEMPERATURE …

    requires relatively less energy to increase its temperature to 540° C than air entering the boiler at -10° C. Therefore, warmer air is expected to provide an efficiency boost to a steam boiler. Second, given a gas with constant mass, a temperature increase causes volumetric expansion and a decrease in density.Learn More
