Industrial furnaces and associated processing equipment. Method of measuring energy balance and calculating energy efficiency - Evaluation of various kinds of efficiency1 Scope This document specifies classifications and designations in the methodology of energy efficiency evaluation of industrial furnaces and associated processing equipment (TPE), including energy efficiency in terms of exergy as well as enthalpy. This document does not apply to the following types of TPE: blast furnaces, basic oxygen furnaces, coke ovens; furnaces that generate gases to be used as fuel (including by product gases); special
