Abstract: Method for drying, crushing and distribution of solid fuel for a solid fuel boiler, for example a fluidized bed boiler. According to the invention moist fuel (9) is crushed and dried by intermixing gas and/or ash (13,14) in a unit (12). The fuel is set in motion, for example in a cyclone (15), together with gas (13), and is divided into several subflows (27-29) to be fed into the boiler at different points (4).
