Date/Time: Date(s) - 23/08/2022 - 25/08/2022( 8:00 am - 5:00 pm )
Location: Malaysia, Kuala Lumpur


Overview

Boilers are an important asset used for various purposes in different industrial plants. It’s one of the main application to produce high-pressure steam for process applications and power generation. Operation and maintenance of Boilers are critical to ensure a safe and efficient plant environment. This training ensures participants gain a comprehensive understanding of commercial, industrial, and utility boiler systems. This training covers the principle of operation of steam boilers, types and the main components of steam boilers. It will also focus on the study of correct operation and routine maintenance and safety. Participants will also learn how to improve boiler efficiency, energy cost saving methods, and maximize safety.
