ABSTRACT:
An arrangement for converting a conventional oil boiler to a boiler with moist, granular and solid fuel, utilizes a fuel combustion gas dryer connected to the combustion gas line of the boiler, and a solid fuel combustion device to replace the oil burner. The combustion gas dryer is a so-called circulating fluidized bed (CFB) dryer together with a particle separator and a combustion gas center tap has been fitted into the oil boiler, through which center tap hot combustion gas has been set to be mixed with combustion gases of the normal outlet in the desired proportion in order to regulate the temperature of the drying gas of the dryer. The combustion devices may include a cyclone burner.
