Determination of Boiler Maintenance Effectiveness on productivity in a Palm Oil Producing Company: A Case Study

Abstract

Maintenance effectiveness on boiler on productivity in Siat Nigeria Limited was determined in this study. Equipment failure has been a big challenge to industries thereby reducing production rate. Boiler operation process in Siat Nigeria Limited and reasons for failure in operation was investigated. Various components of a boiler system such as vaporizer, superheater, economizer, rotary air preheater air fan and flue gas fan were examined for failure that can lead to its maintenance forecast and performance. Reliability analysis was conducted on the boilers and the result shows that for boiler K1 mean time between failure is 2021.539h/failure, mean time to repair is 95.923h/repair, boiler failure rate is 0.000495 failure/h and availability is 95% respectively. Boiler K2, mean time between failure is determined as 2190h / failure, meantime to repair is 103.717h/repair, failure rate is 0.000457failure/h and boiler availability is 95% respectively. After maintenance on the boilers, the output were 5.330 tones and 6.674 tones respectively.
