### Direct and Indirect efficiency in boilers

Fuel-to-steam or fuel-to-water efficiency is a measure of the overall efficiency of the boiler. It accounts for the effectiveness of the heat exchanger as well as the radiation and convection losses. For space heating boilers and in the BTS-2000 testing procedure, this type of efficiency is called "thermal efficiency." It is an

### Industrial Boiler Efficiency Calculation & Factors

Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best heat rate efficiency, lowest NO x, and also generate the least amount of greenhouse gas.

### 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.
