  • Is a high efficiency, condensing gas boiler the best

    Aug 13, 2018 · Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.Learn More

  • HOW A GAS-FIRED HEATING SYSTEM WORKS

    WHAT TO EXPECT WHEN NATURAL GAS IS FIRED IN A COAL-FIRED BOILER ⇧ Furnace exit gas temperature (FEGT) is likely to increase. Natural gas firing flame emissivity is lower than that for coal. This means the furnace water wall absorption is typically lower with natural gas firing. The amount of heat absorbed by the water walls regulates FEGT.Learn More

  • Efficiency factors in natural gas fired steam boilers

    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
