COMBUSTION OF SPENT SHALE IN FLUIDIZED BED
| R. UUESOO |
| Large amounts of spent shale are produced during oil production from oil shale. This spent shale has a caloric value of about 1100 kcal/kg and could be used as a low grade fuel for energy production. Up to now the spent shale has not been used. The first steps towards the use of spent shale were taken by Raul Uuesoo in the fifties [1-3]. He investigated the combustion of spent shale in a fluidized bed, adapted combustion theory for spent shale particles and provided the foundation for calculations for spent shale furnaces. A part of his investigations are reported in short form in this article. |
