Abstract
Abstract:
In this paper, thermoeconomic optimization method based on productive structure technique is applied to a co-generation plant. The co-generation plant consists of a water-tube boiler, steam turbine, feed-water pump, deaerator, condenser, process-heaters and condensate tank. Global optimization of the whole plant is carried out based on separated local optimizations of different main components. The local optimization technique requires thermoeconomic and mathematical models. The results show that the boiler efficiency increases from 81% for the initial (normal) operating conditions to 90.48% for the optimum ones. On the other hand, the process-air heater efficiency increases from 63 % to 64.5% for the optimum operating conditions. Moreover, as a global result, about 11.53 % of the total product cost for all components of the plant is reduced when using optimum operating conditions other than normal ones.
