In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called “Ultra-Low NOx” (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas.View More
Wellons utilizes a urea-based selective non-catalytic reduction (SNCR) system to lower the NOx emissions in the flue gas from the boiler system. The SNCR system is designed to lower the uncontrolled NOx emissions in the stack flue gas by approximately 50%.View More
When it comes to finding an energy efficient steam boiler, it’s critical to consider NOx emissions standards. Nitrogen Oxides, commonly referred to as NOx, is a family of poisonous gases. These gases are best known for their role in air pollution, contributing to occurrences of acid rain, smog, and the deterioration of the ozone layer.View More
Since 20th December 2018, medium combustion plants (excluding plants and gas turbines) for new buildings, which commercial boilers fall under, with a thermal input between 1MW to 50MW must stay below NOx emissions of 100mg/NM³ (gas) or 200mg/Nm³ (oil).View More
NOx is a term that is used to refer to nitrogen oxides, gasses that are created during the combustion process when nitrogen in the fuel that boilers use comes into contact with oxygen in the air. The amount of NOx emissions formed in this process is affected by a variety of factors, including the amount of nitrogen in the fuel, flame temperature, combustion air temperature and excess air levels.View More

NOx pollution is emitted by automobiles, trucks and various non-road vehicles (e.g., construction equipment, boats, etc.) as well as industrial sources such as power plants, industrial boilers, cement kilns, and turbines. NOx often appears as a brownish gas.View More
When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 oils have been achieved. Low nitrogen oil is used most frequently in southern California.View More
However, selecting a gas or oil furnace isn’t a one-size-fits-all decision. American standard knows that one residential furnace might not cover the needs of every customer. That’s why a variety of gas and oil furnaces are available to choose from. Have a look at what American Standard has to offer.View More
Jun 21, 2019 · NOx is a generic term for the nitrogen oxides that are most relevant to air pollution, namely nitric oxide (NO) and nitrogen dioxide (NO 2). These gases are usually produced from the reaction between nitrogen and oxygen during the combustion of hydrocarbon fuels in air, especially at the higher temperatures encountered in car engines and boilers.View More

NOx What it is: NOx is a generic term for the chemical compounds made of nitrogen and oxygen.The air we breathe and use for combustion is 20.9% oxygen (O2); 79% nitrogen; and .1% other. In the combustion process, some of the nitrogen and oxygen in the air combine to create NOx.View More
Hot water boilers are not exempt from either the Major Source or Area Source Rules. Hot water heaters with a capacity of no more than 120 gallons, a pressure of 160 psig, and controls in place to limit water temperature to no more than 210°F are exempt from the Area Source Rule.View More
Jun 12, 2017 · NOx can be generated in combustion processes, even if “clean fuels” such as hydrogen or natural gas are being used. The main source of NOx in gas-heated industrial furnaces is called thermal NO. There are two other modes of formation: prompt NO and fuel-bound NO. These are, however, both negligible in industrial furnaces.View More

Boilers. Our different types of boiler systems are made to be suitable for a variety of homes. The most suitable central heating boilers for a smaller home are our combi boilers, while a traditional heat only or system boiler is ideal for a home with multiple bathrooms.View More
The use of a small amount of steam was less expensive than reworking the boiler to add approximately 14 percent EFGR to achieve the required NOx emissions level of 0.03 lb/MM Btu (HHV).View More
The boiler achieves a NOx emission level of just 38 mg/kWh compared to current Level 1 regulatory limits of 250 mg/kWh. As a result this boiler qualifies for additional …View More
LOW NOX BOILERS AND BURNERS Available for ALL Hurst Boilers Our boilers can burn any liquid or gaseous fuel; and come in sizes from 100 to 2,500 horsepower with pressures to 450 PSI. Hurst boilers are designed and engineered with larger furnaces, providing for inherently lower NOx emissions.View More
