As he crunched the numbers by hand—subtracting the moisture in the fuel, the hydrogen losses, and the dry flue gas heat—he realized Boiler No. 7 wasn't failing. It was starving. The modern control system was optimizing for a grade of coal the plant hadn't used in a decade.
ASME PTC 4.1-1964 outlines procedures for determining steam generating unit efficiency using either the direct input-output method or the indirect heat loss method. The standard dictates precise measurement techniques for fuel, steam, and losses such as dry flue gas, unburnt carbon, and radiation. For further documentation on the standard's application, view the material at Scribd . ASME PTC 4.1 Boiler Efficiency Testing - Scribd

The ASME PTC 4.1-1964 code provides standard procedures for calculating steam generator efficiency via direct (input-output) or indirect (heat loss) methods. While superseded by ASME PTC 4-2013, the 1964 code is still utilized in industry for determining performance parameters like heat output and fuel consumption. For more details, visit ASME .
