The passage around this formula
with both temperatures in kelvin. The following is my own illustrative calculation, using representative round numbers rather than any specific project’s measured temperatures, to show how sharply this ratio depends on the lift between the waste-heat source and the district-heating supply it must reach — commonly on the order of 70–80 °C in an established European district-heating network. Lifting a relatively cool waste stream at 30 °C (303 K) to a 75 °C (348 K) supply gives = 348/(348-303) 7.7 ; lifting a warmer waste stream at 45 °C (318 K) to the same 75 °C supply gives 348/(348-318) = 11.6 . Real ammonia heat…
