7 Ways to Improve Boiler Efficiency Without Costly CAPEX

Aug 13, 2021 · 1. Tune the Burner Regularly For proper combustion of fuel inside the boiler, a certain amount of oxygen is required. If too little air is present, the carbon in the fuel will be oxidized, making carbon monoxide. This causes less heat to release because the fuel isn't completely burned, which lowers fuel use efficiency. Low air generates soot, smoke and …
