The most basic way to measure NO x is "Simple NO x " with a single sensor. NO (nitric oxide), the primary component of NO x, is measured directly with a gas sensor.The NO to NO 2 ratio is then assumed based on the type of combustion fuel and process, from which the NO:NO 2 ratio historical data has been gathered. The NO x is then calculated using the measured NO and assumed NO:NO 2 ratio.Get A Quote
1.4.3 Emissions3-4 The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide (SO2), and particulate matter (PM). Nitrogen Oxides -Get A Quote
Feb 09, 2021 · Aerial emission sampling of four natural gas boiler stack plumes was conducted using an unmanned aerial system (UAS) equipped with a lightweight sensor–sampling system (the "Kolibri") for measurement of nitrogen oxide (NO), and nitrogen dioxide (NO 2), carbon dioxide (CO 2), and carbon monoxide (CO).Flights (n = 22) ranged from 11 to 24 min in duration at two different sites.Get A Quote

26% 25%. Kraft recovery boiler. (TFN ≈ NO) This would be the NO profile if all released fuel-N was fully oxidized to NO Predicted final NO emission. BFB - NOx chemistry takes place in the air jets (more generally, where furnace gas and combustion air mix) Recovery boiler - NOx chemistry between air levels.Get A Quote
For use on automobiles, the invention provides a compact device for measuring the concentration of a nitrogen oxide in a combustion gas such as an exhaust gas of an internal combustion gas. The device has an ion pumping cell using an oxygen ion conductive solid electrolyte to adjust the partial pressure of oxygen in a gas diffusion chamber and a sensor such as an oxygen concentration cellGet A Quote
