7. 5. Co-Combustion of Municipal Solid Waste and Animal Waste : Experiment and Simulation Studies

   Author : Farzad Moradian; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resursåtervinning; Resource Recovery; Resursåtervinning;

   Abstract : Co-combustion of animal carcasses and slaughterhouse waste products (animal waste), which are classed as high-risk infectious waste, has been considered as a “fuel opportunity” for waste-to-energy boilers. In this study, the impact of co-combustion of animal waste with municipal solid waste (MSW) on operational issues such as bed agglomeration, deposit formation and emission was investigated, employing experimental and theoretical methods.
