  • Understanding Oxygen Measurement in Flue Gas Streams

    Jun 29, 2021 · Natural gas fired equipment can run with as little as 1% to 2% excess O 2 since fuel and air can mix thoroughly. When combustion is more difficult, the excess amount may need to be higher. For example, a pulverized-coal-fired boiler will run around 3 to 4% excess O 2, and a municipal solid waste boiler will be even higher, perhaps 5 to 7% Learn More
