Abstract

PT. POMI Paiton Unit 3 is one of big steam power plant in Indonesia that provideelectricity with a capacity of 1 x 815 MW. This power plant requires a large amount ofcoal to produce electricity with a lot of large quantities, estimates of the total consume coalamounted to 3.06 million tons / year. The performance of the power plant PT. POMI Unit3 can be optimized by modifying the Heat Exchanger Network (HEN). Pinch method isused to optimize HEN, this method provides a good opportunity in the design or inevaluating HEN system. Research has been carried capable increase efficiency of 0.5% ofthe power plant that was originally 28.45% to 28.95%, and can reduce fuel use by 1.71 kg/ s initially as much as 97.99 kg / s to 96.28 kg / s, and can also be reconstructed from there-arrangement of Heat Exchanger Network of Power Plant PT. POMI Unit 3 Paiton.
