摘要
The invention relates to an arrangement for converting a conventional oil boiler (1) to a boiler with moist, granular and solid fuel, in which arrangement a fuel combustion gas dryer (3, 4) is used, connected to the combustion gas line (6, 7) of the boiler, and a solid fuel combustion device (2) to replace the oil burner. The combustion gas dryer (3, 4) is a so-called circulating fluidized bed (CFB) dryer (4) together with a particle separator (3) and a combustion gas centre tap (6.2) has been fitted into the oil boiler, through which centre tap hot combustion gas has been set to be mixed with combustion gases of the normal outlet (6.1) in the desired proportion in order to regulate the temperature of the drying gas of the dryer (4). When most advantageous, the combustion devices (2) include a cyclone burner (2), known in itself. IMAGE
