    Abstract: A classifier is provided with: a housing constituted so as to take in air from the bottom in an outer peripheral area of an inner space; a flow correcting unit provided on the inside wall surface of the housing and constituted so as to change the direction of the airflow toward the center axis side of the housing; and a ring shaped rotating unit provided rotatably in an inner peripheral area positioned on the inner peripheral side of the outer peripheral area in the inner space of the housing and constituted so as to classify particles accompanying the airflow. The ring shaped rotating unit has a plurality of rotating blades arranged and spaced around the axis of rotation of the ring shaped rotating unit. The external form of the ring shaped rotating unit formed by the plurality of rotating blades in a side view of the ring shaped rotating unit has an angle θ of 75° or less formed by the external shape of the ring shaped rotating unit with respect to a line extending from the ring shaped rotating unit in a horizontal direction toward the outside in the radial direction.

    Abstract: The invention relates to a device and method for controlling the fuel-air ratio during the combustion of ground coal in the firing system of a coal power plant, which comprises means for the pneumatic delivery of ground coal to the burners of the firing system of the coal power plant and means for feeding combustion air to the burners or into the firing chamber of the firing system of the coal power plant and in which the amount of combustion air and the amount of carrier air is controlled. The aim of the invention is to achieve a high reliability of the control combined with low maintenance of the air mass measurement devices for measuring the amount of combustion air and carrier air. According to the invention, this aim is achieved by a measurement device for measuring the amount of combustion air which, according to the correlation measurement method, evaluates the triboelectric effects on sensors which are arranged in series in the direction of flow of the combustion air and thus measures the flow velocity of the combustion air. To this end, between 0.1 mg and 10 mg of fine-grained particles having a particle diameter of between 20 μm and 200 μm are introduced per m
    3 air into the suctioned fresh air. The introduction of particles into the suctioned fresh air is carried out essentially during the starting phase of a firing system of a coal power plant. The measurement of the amount of carrier air is preferably carried out by means of a correlation measurement device that evaluates the triboelectric effects on sensors which are arranged in series in the carrier air stream in the direction of flow of the carrier air.
