Abstract: In a paper making machine, apparatus for cleaning a doctor blade which extends across a roll of the paper making machine in the cross-machine direction includes a frame mounted for oscillating movement over the length of the doctor blade, which frame is driven by drive apparatus preferably in the form of an air cylinder whose piston is coupled to the frame to oscillate the same and a blade cleaning brush carried by the frame in a manner such that the brush engages the doctor blade to clean the same as the frame is oscillated by the drive apparatus. The brush preferably comprises a rotatable, disc-shaped brush equipped with an air motor for rotating the same. The present invention provides the capability of cleaning the doctor blades of paper machines without necessitating interruption of the machine operation.

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.
