Pitfall #2: Radiation Loss (L6) Curves
The standard provides empirical curves for radiation loss based on boiler load percent. These curves are from 1964 data. If you apply them to a modern fluidized bed boiler or a HRSG, you will get nonsense. The code allows you to substitute manufacturer data for L6, but you must document the deviation. Asme Ptc 4.1.pdf

Important Note for Searchers: You may notice that ASME has released PTC 4-2008 (and later revisions) which supersedes PTC 4.1 in a technical sense. Why, then, is "ASME PTC 4.1.pdf" still the most searched term? Because legacy plants, older contracts, and many university curricula still rely on the 4.1 structure. Furthermore, the 2008 version simplified many calculations, but engineers often prefer the granular detail of 4.1 for troubleshooting individual heat losses.
