Combustion Trim Systems Comparison for Oxygen

The Oxygen Trim system uses a sensor to measure the excess oxygen in the flue gas, and will change the fuel or air flow to correct this level to match a pre-set level. The setup generally includes a combination of setpoints (for different firing rates and fuels) and actuator values that provide a known quantity of correction.

The new standard in flue gas venting safety | 2019-11

For a flue gas venting installation, it mitigates risk because it is a matter of life or death. It is particularly important that the appropriate FGV piping system be used to ensure poisonous gases, such as carbon monoxide, are properly exhausted. In Canada, the gas code adopted the ULC S636 standard for nonmetallic FGV systems.
