  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.

  4. 2. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning

    Author : Lennart Gustavsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical modelling; fuel injection; nitrous oxide; fluidized bed combustion; fluidized beds; afterburning; homogeneous heterogeneous reactions; N2O reduction; fluidized bed boiler; N2O emissions;

    Abstract : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. READ MORE

  7. 5. Methanation of biosyngas in a fluidized bed reactor

    Author : Martin Seemann; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE
