### Improve Your Boiler's Combustion Efficiency

The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings are: Annual Savings = Fuel Consumption x (1–E1/E2) x Fuel Cost = 29,482 MMBtu/yr x $8.00/MMBtu = $235,856 Flue Gas Analyzers test kits

2021/7/27 · Combustion Efficiency — This is a measure of how well a boiler is burning fuel. It specifically refers to the total heat released during combustion, minus heat that is lost in the combustion process. Under ideal circumstances, a boiler's combustion will result in low levels of unburned fuel and excess air. However, in a real-world
