$$ \eta = 100 - (L_1 + L_2 + L_3 + L_4 + L_5 + L_6 + L_7 + L_8) $$

A: No. For HRSGs, you need ASME PTC 4.4 (Gas Turbine Heat Recovery Steam Generators). PTC 4.1 is for direct-fired steam generators (coal, oil, gas, biomass). Asme Ptc 4.1.pdf

Introduction In the world of thermal power generation, precision is profit. For engineers, plant managers, and energy consultants, the difference between a well-performing boiler and a failing one is often measured in fractions of a percentage point. When it comes to establishing a standard for testing the performance of steam generators, one document stands above the rest: ASME PTC 4.1.pdf . $$ \eta = 100 - (L_1 + L_2
