    Boiler Combustion |

    Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the …

    Combustion Efficiency and Excess Air

    Example - Oil Combustion and Heat Loss in the Flue Gas. If. the temperature difference between the flue gas leaving a boiler and the ambient supply temperature is 300 o C, and; the carbon dioxide measured in the flue gas is 10% - then, from the diagram above. the flue gas loss can be estimated to approximately 16%.

    Natural Gas Fired Boilers

    Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air). Steam and exit gas temperatures.

    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 …

    5 The Combustion Process Combustion is a chemical reaction of rapid oxidation started by the correct mixture of fuel, oxygen and an ignition source. The chemical reaction for natural gas is: CH4 + 3O2 = Heat + 2H2O + CO2 + O2 Where: CH4 = 1 cubic foot of Methane Gas (Natural gas) 3O2 = 3 cubic feet of Oxygen Heat = 1027 BTU's of energy produced from the chemical reaction

    Tips on properly sizing the combustion air openings | 2016

    Sep 28, 2016 · As a grizzled old boiler room veteran now, I see many boiler rooms with inadequate combustion air. According to the International Fuel Gas Code, Section 304, each boiler room should have two openings, one within a foot of the floor and one within a foot of the ceiling. This is to allow natural ventilation inside the boiler room.

    Slow combustion (smoldering) is the slow, low-temperature, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel. It is a typically incomplete combustion reaction.

    Sealed Combustion Heaters: What are they and do I want one?

    Dec 19, 2016 · Sealed Combustion Defined. The simple definition of a sealed combustion heater is that the equipment uses only outside air for the fuel-burning (combustion) process that takes place in the equipment. A pipe is used to bring outside air into the gas burning appliance, and another pipe sends the exhaust products to the outdoors.

    Posted on February 23, 2018 at 12:00 am. Converting your wood fireplace to a gas one is a great idea, as it will make it easier for you to use your fireplace, and require less maintenance than a wood burning fire. Although the conversion of your fireplace is generally a straightforward one, it should always be done by professional, as not only will it ensure it’s done properly, but also in
