Nitrous oxide emissions control by reburning

Final Report: No{sub x} Emissions from By Product Fuel Combustion in Steel Making, September 15, 1996 - October 15, 1999

“…Nonhydrocarbon fuel reburning has also been performed with some effectiveness (Bortz and Offen. 1987;Chen et al, 1986;Rutar et al, 1996).…”

Experimental and Mechanism Study of Homogeneous N2O Decomposition with Biomass Gasification Gas and Its Components

“…It should be attributed to the difficulty to break the bond of CH 4 to produce free radials, such as H atom, at temperatures lower than 1000°C. According to the research performed by Rutar et al (1996), to reduce N 2 O emissions using different reburning fuels, the reburning temperature was chosen from 1330 to 1630 K (especially from 1370 to 1630 K) for CH 4 . They revealed that the order of reductive ability was H 2 > C 2 H 4 > CH 4 and C 2 H 6 > CO with the same calorific capacity of fuel in this temperature range.…”

“…It has been demonstrated that the N 2 O emissions could be decreased by burning some reducing gases, such as H 2 , CH 4 , CO, and some other hydrocarbons (Skottene and Kjell, 2007;Dong et al, 2009;Rutar et al, 1996;Vandooren and Van Tiggelen, 1997). Skottene and Kjell (2007) indicated that H 2 was effective to reduce the N 2 O, which could be mainly attributed to the reaction of H + N 2 O <=> N 2 + OH.…”

High Fuel-Air Ratio (FAR) Combustor Modeling

“…A brief list of articles is provided in the reference section. The papers cover lean premixed, aircraft engine, catalytic, and fluidized-bed coal combustors [2][3][4][5][6]. These papers illustrate how a variety of combustor types can be modeled by the CRM method.…”
