Abstract :This study reveals the exergoeconomic analysis of stenters by using Specific Exergy Costing insert ignore into journalissuearticles values(SPECO); method. The cost balances and auxiliary thermoeconomic relations were developed for direct gas heated insert ignore into journalissuearticles values(DGHS); and hot oil heated insert ignore into journalissuearticles values(HOHS); stenters by the application of the control volume models. The exergy cost of the evaporation of water was selected to be the main parameter. It was shown that the falling-rate period of drying led to the highest exergy costs, while exergy costs varied between 0.19 US$/GJ and 0.59 US$/GJ depending on the drying periods. Increasing the exhaust air humidity ratio and the residual moisture content of the fabric outlet decreased the exergy costs linearly.
