  • What does boiler turndown ratio mean? | U.S. Boiler Company

    Dec 17, 2020 · Boiler turndown ratio defined. Boiler turndown is the ratio between a boiler's maximum and minimum output. Depending on the burner's design, it may have a turndown ratio between 5:1 and 10:1 or even higher. A 5:1 turndown means the boiler's minimum operating load is 20% of the boiler's full capacity ( capacity divided by 5).Learn More
