Abstract
The key to proper allocation of fuel and feedstock costs to the products from a plant or from any one of its components is the commodity called exergy - the central concept of the Second Law of Thermodynamics, commonly named available energy or availability. The methods for composing exergy cost flow diagrams will be explained. The results will be shown for several plants - electric-power, co-generation, coal-gasification, and others. The application of such results will be shown for cost-accounting, for plant operation economics, for maintenance decisions, and for design decisions - at both the preliminary and detailed design states.
