Abstract
The coal switch program carried out by Power Plant of Paiton Unit 8 has caused excessive slagging in the boiler area that is not installed sootblower, the formation of slagging and fouling causes problems and chain effects in boiler operations which result in a decrease in boiler efficiency. A 2019 boiler inspection revealed significant slagging located on the rear screen tube, vertical backpass tube, lower rear reheat tube banks, and the upper location between the final reheat and final superheater division panels. This study aims to directly observe the performance of the boiler, then a calculation analysis is carried out using the direct method, namely by making a direct comparison between the heat absorbed by the working fluid in the boiler with the heat produced by fuel before and after the addition of a sootblower in the superheater division panel boiler area of Power Plant of Paiton Unit 8. The observation results found that the addition of a sootblower increased boiler efficiency by 3,115%, reduced CO2 gas emissions by 21,983,423 tons e CO2 and saved coal consumption costs of USD 1,550,640.
