Stack Airflow Measurement

For stack airflow measurement in coal fired boilers, all facilities subjected to 40 CFR Part 75 must have a flow monitoring system that satisfies continuous monitoring requirements. Air Monitor’s CEMS flow rate monitoring system meets the EPA mandated requirements relative to 40 CFR Part 75. Key advantages of an Air Monitor CEMS system are:

EPA Requirement	Air Monitor Solution
Measurement location	Dual platforms not necessary to pick up velocity profile stratification in the stack
Interference check	AUTO-purge III clears debris in particulate-laden airflow
Calibration error	AUTO-cal function calculates calibration error
Relative accuracy	Air Monitor’s multi-point averaging approach ensures high accuracy matching RATA tests performed by third parties
Bias	Pre-RATA test available from Air Monitor
