The test combustion of Estonian oil shale was carried out in approximately 1 MWth circulated fluidized bed (CFB) test facilities of Hans Ahlstrom Laboratory, Karhula, Finland and Lurgi AG, Frankfurt/Main, Germany.
The objective of the tests was to verify whether Estonian oil shale can be burnt in the atmospheric CFB boiler at a sufficient carbon conversion rate and acceptable pollutant emission levels.
In the second step, a proposal for the design of a 100 MWth demonstration plant was prepared.
