15 Ways to Increase Boiler Efficiency in Your Facility

Jul 30, 2020 · Too much air also reduces efficiency. The extra air comes in cold and sent out the stack hot, wasting heat. An optimal process provides just enough air for the fuel to burn safely. To achieve this, we measure the amount of air needed with an O2 probe. We insert the probe into the stack while we tune the burner for optimum boiler efficiency.
