Boiler Turndown Ratio: What It Is and Why It Matters

If the boiler does not have a high turndown ratio, facilities don't have many options for controlling how much fuel they're using. Operating a boiler system with a high turndown ratio offers these facilities greater efficiency because it can operate at a lower capacity during low-demand times while also meeting those peak demands with ease.

Boiler Operations That Affect Efficiency (Part 2)

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).

Control system for a boiler and method therefor - …

Of course, the steam/fuel ratio is an ultimate measurement of boiler efficiency since it corresponds to a ratio of the output energy over the input energy. Thus, in effect, a cross limiting scheme is used with regard to the steam/fuel ratio to provide for variation in accordance with this ratio where perhaps heterogenous fuel bed conditions might warrant it.
