Resumo
More buyers and sellers today are relying on economic worth models to discriminate between the multitude of coal products that are available in the marketplace. A variety of terms have been used to describe economic worth, such as comparative value ratings, equitável product costing, etc. The economic worth approach to coal selection requires a working knowledge of coal quality and a clear understanding of the use for which the coal is intended. Computer models orchestrated by engineers help establish the relationships between product acceptability, cost, and value within the context of operational constraints and process variables. Assessment of coal value must be carried through to some intermediate or final product by determining the impact that quality has up through that stage in the finishing process where the impact of coal quality on process economics ends. In this regard, the best interests of both buyer and seller are served when the delivered price of a seller's product, which has already been screened for acceptability, falls within a buyer's budgetary constraints after its price has been adjusted for predicted performance in the process for which it is intended. Of course, the higher a coal's value in a given process and the lower its delivered cost, the greater the savings or economic worth to the customer (Figure 1).
