      1.4 Natural Gas Combustion - US EPA

       · PDF file

      Sulfur Oxides - Emissions of SO2from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet. However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2emissions.

      Low Emission Boilers | LOW NOx | Hurst Boilers

      To produce lower emissions, our boilers employ technologies such as; gas and air pre-mix, flue gas recirculation, and thermal reduction. We have also developed new control systems that utilize microprocessor-based fuel/air ratios offering superior combustion. Hurst Boilers are designed and engineered with larger furnaces.

    • natural gas fired boilers

      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. Upon switching from coal to natural gas, heat transfer characteristics of a boiler will be impacted.

      Natural Gas Fired Boilers

      Natural gas contains very little sulfur and as a result, produces very low SO2 emissions. The most common additive to add odor to natural gas is Mercaptan (CH3SH : Methanethiol). WHAT TO EXPECT WHEN NATURAL GAS IS FIRED IN A COAL-FIRED BOILER ⇧ Furnace exit gas temperature (FEGT) is likely to increase

      Most industrial and commercial users of packaged boilers now fire natural gas. You’ll find #2 oil commonly used as a back-up fuel for hospitals and industry, and in some geographic areas without natural gas service. This information is intended for use by the vast majority that fire natural gas and also touches on #2 oil.

      Introducing the lowest NOx boilers on the planet

      In September 2018 a mandatory maximum NOx emissions level of 56mg/kWh for gas and LPG boilers and 120 mg/kWh for oil-fired boilers was imposed, but for some local authorities it’s not low enough and they are demanding ultra-low NOx boilers with a maximum emissions level of 30mg/kWh.

      Guideline A-9: NOx Emissions from Boilers and Heaters

      The purpose of this Policy Guideline is to reduce smog in Ontario, by reducing the emission of oxides of nitrogen by new (or modified), large, boilers and heaters. This guideline specifies limits for emissions of oxides of nitrogen (NOx”) for new or modified fossil-fuel boilers and heaters which have a fuel energy input greater than 10 million Btu/h (10.5 GJ/h).

      Low excess air firing can be used on most boilers and generally results in overall NOx reductions of 5-10% when firing natural gas. Low Nitrogen Fuel Oil When firing fuel oils, NOx formed by fuel-bound nitrogen can account for 20-50% of the total NOx level.
