How to calculate the thermal efficiency of a gas boiler

To determine the overall boiler thermal efficiency, some measurements are required. The most common test used for boilers is the flue gas analysis using an Orsat apparatus to determine the percentage by volume the amount of CO 2, CO, O 2, and N 2 in the combustion gas leaving the stack. Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel ratio to improve the boiler efficiency.
