### Boiler Efficiency Improvement & Heat Loss Explained in

Jan 22, 2019· Boiler Efficiency Improvement Steps: This heat can be utilized to preheat the air or water used in a boiler. The optimum ratio of fuel to air and keeping the excess air as low as possible keeping in mind the complete combustion of fuel can increase the furnace temperature thereby increasing the radiation heat. Reducing excess air by 5% can increase boiler efficiency by 1%.
