Analytical techniques for measuring nitrous oxide

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. Selective non-catalytic reduction reduces NOx up to 70%.

The Formation of Nitrogen Oxides in a Pulverised Coal Boiler

The Formation of Nitrogen Oxides in a Pulverised Coal Boiler Abstract The oxides of nitrogen (NOx) are airborne pollutants that result from the combustion of pulverised coal. The aim of this project is to identify operational methods that reduce the NOx emissions from a coal fired boiler whilst maintaining satisfactory performance.

Nitrogen Oxides (NOx) Primer - Babcock & Wilcox

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.

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
