Convert to LHV if needed: Efficiency (LHV) = Efficiency (HHV) × (HHV/LHV). For methane, HHV/LHV ≈ 1.11 → η(LHV) ≈ 88.6%.
For steam generator efficiency tests, post-test uncertainty analysis is essential to confirm that test requirements have been met. Industry guidance suggests that typical uncertainties for power output are within 1.1%. Asme Ptc 4.1.pdf
