Guide to Low-Emission Boiler and Combustion Equipment

This webpage provides a brief description of nitrogen oxide (NOx) emissions and general information about the air quality programs in New England that focus on reducing NOx. Nitrogen Oxides are a family of poisonous, highly reactive gases. These gases form when fuel is burned at high temperatures. NOx pollution is emitted by automobiles, trucks and various non-road vehicles (e.g., construction …

Hog Fuel Boiler RACT Determination

Fuel nitrogen conversion is the more important NOx-forming mechanism in residual oil boilers. It can account for 50 percent of the total NOx emissions from residual oil firing. The percent conversion of fuel nitrogen to NOx varies greatly, however; typically from 20 to 90 percent of nitrogen in oil is converted to NOx. Except in certain large units having unusually high peak flame temperatures, or in

Nitrogen Oxide Emissions of Boilers in Finland

at their maximum rated capacity the refinery-wide rate of nitrogen oxides emissions from these units would not exceed: (i) 0.14 pound (0.064 kilogram) of nitrogen oxides per million BTU of heat input when operated on gaseous fuel; (ii) 0.308 pound (0.14 kilogram) of nitrogen oxides per million BTU of heat input when operated on liquid fuel;

1.3 Fuel Oil Combustion

Dec 18, 2017 · 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. These emissions aren't just coming from boilers, but also from vehicles and stationary engines.

Low Nitrogen Oxide (NOx) Emission Boilers

NOx formation in boilers. NO x (oxides of nitrogen) refers to the cumulative emission of nitric oxide (NO), nitrogen dioxide (NO 2 ), and trace quantities of other nitrogen-bearing species generated during combustion. Combustion of any fossil fuel generates some level of NO x due to high temperatures and the availability of oxygen and nitrogen from both air and fuel.

approximately 38,000 tons NO2, peat-fired boilers and boilers fired with a mixture of fuels, emitting approximately 12,000 tons NO2 each. By 2005, the total NOXemission from energy production would increase 50 percent to. approximately 160,000 tons if left uncontrolled. The emission level would be 140,000 tons if.
