Coal Pipe Balancing Airflow Sciences
1. Utilize the Advanced Coal Flow Measurement (ACFM) equipment to accurately measure both air flow and coal flow rate in each pipe. 2. Analyze the data to determine if the balance is within industry standards of ±5% for the air flow balance and ±10% for the coal flow balance. 3. For those mills that are outside of industry specifications,
