For large industrial natural gas-fired boilers, typical PTC 4.1 efficiency is approximately . The dominant losses are wet gas losses (~10%) and dry gas losses (~4%). Asme Ptc 4.1.pdf
The code does prescribe procedures for:
When you open an , you are immediately confronted with two distinct paths to calculate efficiency. Understanding when to use each is critical. Despite newer codes, the 1974 reaffirmation of PTC 4
