      15 Ways To Increase Boiler Efficiency | Rasmussen Mechanical

      Oct 01, 2018 · Much like the return of condensate to the boiler, recovering the heat from the boiler blowdown can increase boiler efficiency. The blowdown valve is used to remove boiler water which contains soluble and insoluble solids. It helps reduce the level of dissolved solids in the boiler water to prevent the boiler scale.

      Industrial Boiler Efficiency Calculation & Factors

      Turndown. Turndown is the ability of the boiler to achieve a wide range (from low to high) of output. If a boiler has a high turndown ratio, then it is able to supply steam at lower rates without shutting down and restarting. This means that higher turndowns can offer efficiency improvements when demand varies.
