  • O2 Trim for Increased Boiler Efficiency & Emissions Compliance - Boiler Blog | Nationwide Boiler Inc. - Nationwide Boiler …

    2021/10/1 · One way to increase boiler efficiency is to use oxygen trimming, or O2 Trim, at the stack. A typical burner will operate from 3 to 4% O2 at 50% boiler load and higher. This stack O2 concentration corresponds to the amount of excess air at the burner, and excess air is required for burner operation to assure complete combustion of the fuel.Get Price
