Manufacture of logs and ovoid or cylindrical nuts (length = diameter) for burning, from 2nd grade byproducts mixed with coal or coke fines. The log consists of a combustible rigid support 1 surrounded by a compacted mixture of products of vegetable origin amalgamated with coal fines 2; the whole coated with a thickness of wood sawdust granulate 3, to avoid the coal dirt and to facilitate its colouring 4. This coating will be more or less dark in colour 4, depending on the content of the products employed. <IMAGE>
