Convert to LHV if needed: Efficiency (LHV) = Efficiency (HHV) × (HHV/LHV). For methane, HHV/LHV ≈ 1.11 → η(LHV) ≈ 88.6%.

While the official, copyrighted standard must be purchased from the ASME or authorized resellers, the historical 1964 edition of is widely available for free download in PDF format on various engineering resource websites [0†L4-L6]. The PDF file is approximately 3.38 MB to 3.47 MB in size and typically around 51 pages long. When using such documents, it is always prudent to verify their completeness against official sources.

The code requires you to measure the flue gas temperature after the last heat recovery device (economizer or air heater). However, if air infiltration occurs downstream, PTC 4.1 provides a complex correction to back-calculate the temperature at the air heater exit. Most engineers skip this; the best engineers follow Appendix F to the letter. Convert to LHV if needed: Efficiency (LHV) =

L₇ is inversely proportional to load. At 50% load, L₇ doubles. The PDF file is approximately 3
