WebBoiler manufacturers usually provide boiler efficiency curves over several firing rates (e.g. 100%, 75%, 50%, 25%) based on laboratory results. These curves, however, rarely go below 10% of the firing rate (10:1 turndown ratio) and if they do, it should be important to take note of the excess air levels.
