  2. 1. Nitrous Oxide Emission from Circulating Fluidized Bed Combustion

    Author : Lars-Erik Åmand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air supply dependence; fluidized beds; homogeneous heterogeneous reactions; fluidized-bed boilers; bed temperature dependence; N2O emissions; circulating fluidized-bed boilers; gas-concentration profiles;

    Abstract : In the present thesis N2O results are presented from several measurement projects on two commercial circulating fluidized bed (CFB) boilers. Traditional parameter studies have been carried out, as well as test programs where various nitrogen-containing species were injected into the furnace or gas-concentration profiles in the combustion chamber were measured.
