Effect of Impeller Condition on Blower Performance, Case Study: Impeller of K-2201 in Pt. Pertamina RU III

Abstract

The performance of blower depends on impeller condition. This paper is to discuss the open face impeller condition related to performance based on performance curve provided by the manufacturer. The impeller condition is observed under three different conditions. The first condition is that the impeller area is covered by 3 mm thick of fouling. The second condition is that there is a 1 mm of rubbing on the vane and the third condition is the impeller after being repaired. The datas are taken by the actual operation condition. The observed data is then calculated and plotted on OEM performance curve. The result shows that the first condition has the lowest performance; the produced head is 47% lower than the OEM’s.
