How accurate primary airflow measurements

摘要

Primary airflow has a major impact on the efficiency, capacity, and cleanliness of pulverized coal-fired generation. Inaccurate measurements that underestimate primary airflow levels can lead to negative operational outcomes that include increased boiler gas temperatures, flyash loss-on-ignition, excessive NO{sub}X emissions, and higher-than-necessary fan power consumption. We remind you how to avoid those headaches.
