  2. 2. The fate and ash transformations of phosphorus in combustion of biomass and sewage sludge

    Författare :Joel Falk; Marcus Öhman; Nils Skoglund; Dan Boström; Franz Winter; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The combustion of phosphorus (P)-rich biomass has a significant potential to increase the stock of biomass resources available for renewable heat and power production. In addition, the P-rich ashes have the potential as a fertilizer and could reduce the need for non-renewable P resources in agriculture. LÄS MER
