  • 15 Ways to Increase Boiler Efficiency in Your Facility

    Jul 08, 2021 · Over time, soot may build up on the fireside of the boiler tubes, especially with older equipment. This layer of soot acts as an insulator, bringing down the heat transfer rate and increasing fuel use. Because of the lower heat transfer rate, the hot gases pass through without transferring the heat to the water, increasing your stack temperature.Learn More
