  1. 21. Application of the ChlorOut concept in a waste wood fired CFB boiler

    L3-uppsats, SLU/Dept. of Energy and Technology

    Författare :Mårten Carlberg; [2008]
    Nyckelord :superheater; corrosion; alkali; chlorides; ammonium; sulphate; chlorOut; IACM; potassium; KCl; bio fuels; sulphur;

    Sammanfattning : Boilers converting from sulphur rich fossil fuels to alkali and chlorine rich bio fuels often experience an increased super heater corrosion. This is partly due to the increased formation of KCl during combustion of bio fuels. The problem could, for instance, be handled with a sulphur containing additive to the fuel or to the flue gases.

  4. 23. Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Ola Lind; [2004]
    Nyckelord :Sameldning; deNOx; SCR; deaktivering; deaktiveringsmekanismer; katalysatorförgiftning;

    Sammanfattning : Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. LÄS MER
