EPA Stack Testing Method Part 2

Stack Testing
September 01, 20222 min read

Safety applies with equal force to the individual, to the family, to the employer, to the state, the nation and to international affairs. Safety, in its widest sense, concerns the happiness, contentment and freedom of mankind.- William J. Jeffers

EPA Reference Method 1 Part 2

This article is a continuation of how to successfully complete a stack test on natural gas compressor engines using EPA RM1.

Safety

Test ports, flow disturbances, traverse points, OH MY! Not to worry. BAIR has got you covered.

A Proper Measurement

IT is important to first obtain measurements of the stack diameter and upstream/downstream disturbances. An example of an acceptable measurement is as follows:

  • Inside Stack Diameter: 36 Inches

  • Distance from Port to Downstream Disturbance: 18 Inches

  • Distance from Port to Upstream Disturbance: 72 Inches

After obtaining measurements of inside the stack diameter, as well as distances between upstream and downstream flow disturbances, we can now determine how many Traverse Points (or equal areas in the stack) from which we must sample.

On natural gas compressor engines these traverse points are useful because they can be used for sample concentration and differential pressure readings to determine exhaust flow.
