The objective of this study is to evaluate the current boiler performance in a tire industry and to identify areas where improvements can be made based on energy conservation opportunity (ECO). ECO can be performed in various ways, including applying O2 trimming, installing an economizer, implementing blowdown heat recovery system and insulating the condensate tank & pipelines. This study was conducted on three boilers, in which Boiler 03 was a backup boiler without an economizer. The efficiency of the three boilers was calculated using the indirect method according to BS 845-1:1987. The current boiler efficiencies were about 79% for boilers with economizer, and 74% for boiler without economizer. The recommended ECO would give gas bill cost-saving in the range of 0.47 – 1.4% (Rp 18.6 – 36.8 million/month). The investment range would be Rp 400 million – 1.2 billion with simple payback period of 1.2 – 2.7 years. The first priority of ECO mentioned above should be the installation of an economizer with a cost-saving up to Rp 30.2 million/month, which gives a simple payback period of 1.2 years.
