Applying IEC 61511 to Burner Management Systems

This course provides an overview on how to implement a performance based Burner Management System (BMS) and move away from the constraints of a prescription based standard for safety function design, especially when waste fuels are introduced into boilers or process heaters. The IEC 61511 standard is the functional safety standard specific to the Process Industry sector. This standard introduces a safety lifecycle concept which is a structured engineering process to ensure functional safety is achieved in a plant. The standard also focuses on evaluation of process risk and required risk reduction, if necessary. The safety lifecycle approach to BMS will address any deficiencies in design, testing, documentation, maintenance or modification requirements.
