Method and Device for the Combustion of Oil Shale with low calorific value. The schists are crushed (6) in the presence of a hot Drying Gas and fed into a Decompression Chamber (8) where fine grains are Entrained by the gas Drying Filtration means (10) to (13), meeting with coarser grains downstream of its screening.The Drying gas is formed by the hot gases from the combustion chamber (4) and the cooled fume taken away from the combustion chamber into the atmosphere (5).Then the grains are relatively large sieve (17a, 17b) for Separating and Recycling (19) The coarser fraction and introduce them in suspension in the primary Air (25a, 25b) in the combustion chamber.
