FIRING SYSTEM OF A COAL-FIRED POWER STATION WITH DEVICE FOR CONTROLLING THE FUEL-AIR RATIO IN THE COMBUSTION OF GROUND COAL AND METHOD OF OPERATING THE FIRING SYSTEM |
| 摘要 |
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 (10) with average radius rm with 0.1 mm≦̸rm≦̸1.2 mm arranged in channel carrying air in flow direction of air upstream of sensors (11) of correlation measurement device (12) 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 (11). A counter electrode (13, 25) electrically operative relative to electrode (10) is arranged in upstream of sensors (11), and electrode (10) and counter electrode (13, 25) are connected with different poles of a high-voltage source (9) configured for providing a voltage U of 12 kV≦̸U≦̸20 kV. |
