This method calculates efficiency directly by measuring the heat absorbed by the working fluid (water/steam) and dividing it by the heat input from the fuel. Asme Ptc 4.1.pdf
= 5.3 + 11.8 + 0.2 + 0.5 + 0.1 = 17.9% Efficiency = 100 – 17.9 = 82.1% (HHV basis) You are likely searching for "ASME PTC 4
PTC 4.1 provides a chart/table based on boiler rated capacity (Btu/hr or MW). For a given boiler, the loss is assumed constant during the test if the unit is operated near rated load. ASME PTC 4
ASME PTC 4.1 has been formally withdrawn and superseded by ASME PTC 4-2013 (Fired Steam Generators). However, PTC 4.1 remains the industry "gold standard" for legacy boiler efficiency testing, referenced daily in power plants, commercial heating, and engineering audits worldwide. This guide focuses on interpreting and using the original 1964/1998 document.
