Abstract
The efficiency bounds at maximum profit are obtained from finite-time exergoeconomic analysis for three common heat transfer laws: Newton's law (n = 1), a linear pheomenological law in irreversible thermodynami cs (n = 1), and the radiative heat law (n = 4). The relation between o ptimal profit and efficiency of an endoreversible Carnot engine is der ived on the basis of the general heat-transfer law q proportional to D elta(T-n).
