  • Chapter 3 The fuel effect: What is being burned matters

    burned in a boiler. Natural gas, which is primarily composed of methane (CH4), is a lighter than air gas that is typically supplied to buildings via underground distribution pipelines owned by a utility company. Natural gas is the cleanest of the fuels typically used for residential and commercialLearn More

  • Boiler/Burner Combustion Air Supply Requirements and

    The products of full combustion for natural gas primarily consist of carbon dioxide, water vapor, nitrogen and excess oxygen. The oxygen supply for combustion usually comes from air. Because air contains a large amount of nitrogen, the required volume of air is much larger than the required volume of oxygen.Learn More

  • Dealing with the Products of Combustion Part II - HPAC

    Oct 15, 2019 · The combustion process is simply a chemical reaction that combines natural gas (CH4) and oxygen (O2) and ignites them inside a condensing boiler. The resulting chemical reaction produces a flame and large amounts of sensible and latent energy. The sensible energy is released directly to the combustion chamber from the heat of the burner flame.Learn More

  • Boilers - University of Alabama

    Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureLearn More

  • Challenges when Converting Coal-Fired Boilers to Natural Gas

    Sep 26, 2018 · Nitrogen plays no part in the combustion process of natural gas and would, ideally, pass through the boiler without reaction. However, there are three primary processes that create NOx during natural gas combustion: thermal NOx; fuel NOx; and prompt NOx. (See box-out for an explanation of the oxides of nitrogen.)Learn More

  • Residential Gas Boilers | Weil-McLain

    Weil-McLain's line of high-efficiency residential gas boilers include the award-winning Evergreen, the Ultra, the WM97+, the ECO, the ECO Tec and the GV90+.

Available for water and steam systems in sizes from 70 to 399 MBH.Learn More

  • FUNDAMENTALS OF COMBUSTION AND HEAT LOSSES

    HEAT LOSSES in a boiler are well described by the American Society of Mechanical Engineers (ASME) in its rigorous PTC4.1 power test code (1973). The test code applies to any type of fuel used. However, natural gas or fuel oil fire most boilers and heaters in Canada. In such systems, many of the losses listed in the code do not apply.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 Learn More

  • Boiler Emissions 101

    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.Learn More

  • What is a Boiler and How Does it Work? | RealPars

    Aug 19, 2019 · Boilers are an extremely versatile and important piece of engineering equipment, not only for us on a domestic level but at a commercial and industrial level too. To generate heat, we need a fuel source. The reaction of having a fuel source, heat and an oxidizing agent allows for a reaction to take place. This keeps the heat source going.Learn More

  • Steam Boiler: What Is It? How Does It Work? Types Of

    Gas Boilers. Gas steam boilers are powered by natural gas or propane and are more efficient than standard boilers. The fuel for a gas boiler is piped into the boiler from an outside source that is connected directly to the boiler. The distribution of heat using a gas steam boiler …Learn More

  • Guide to Low-Emission Boiler and Combustion Equipment

    The principal mechanism of NOx formation while firing natural gas is thermal NOx, which is very different than firing coal with a modern boiler where NOx is mostly fuel NOx. Thermal NOx occurs through the thermal disassociation and subsequent reaction of nitrogen (N2) and Oxygen (O2) molecules in the combustion air which is approximately 78% N2 and 20.9% O2.Learn More

    Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen.Learn More

  • What is a High Efficiency Gas Boiler? | U.S. Boiler Company

    Aug 21, 2019 · High efficiency condensing boilers produce heat by burning natural gas or propane fuel.
