The purpose of this study is to analyze the effect of feed water temperature on thermoeconomic performance of a boiler used in a coal fired thermal power plant. Thermoeconomic model of the boiler is developed based on second law of thermodynamics. Performance analyses based on exergetic and exergoeconomic criteria are done for the boiler used in a 55 MW power plant. The methodology is explained in detail with the help of an example in order to make comprehensive evaluations. Effect of feed water temperature on the exergetic efficiency of the boiler system, unit product cost of the boiler and unit product cost of feed water heaters has been shown in detail. Optimization has been done for the boiler system as a tradeoff between the unit product cost of feed water from the feed water heaters and unit product cost of the boiler system. The outcomes of this study provide a basis useful for boiler performance analysis and improvement.
