        "note": "The factor of evaporation = (total heat of the steam − the feedwater heat) ÷ 970.3. It is always ≥ 1 because real feedwater is below 212 °F, so the boiler must add the sensible heat too. Divide a 'from and at 212 °F' rating by this factor to get the real output at your feedwater temperature — which is why preheating feedwater (e.g. with an economiser) raises capacity and saves fuel.",
