Abstract
Coal-fired power station with controller for air-fuel ratio in combustion of ground coal, with pneumatic conveying of ground coal to burners of power station. An electrode () with average radius rwith 0.1 mm≦r≦1.2 mm arranged in channel carrying air in flow direction of air upstream of sensors () of correlation measurement device () at distance l with 1× unobstructed width of flow cross-section of the channel carrying the air<l<10× unobstructed width of the flow cross-section of the channel carrying the air in the region of the sensors (). A counter electrode () electrically operative relative to electrode () is arranged in upstream of sensors (), and electrode () and counter electrode () are connected with different poles of a high-voltage source () configured for providing a voltage U of 12 kV≦U≦20 kV.
