摘要:The safety control and command system, such as the burner manage-ment system, requires that the system must be reliable, available and safe. The reliability is based on choosing equipment, with a high level of safety and which is suitable for the safety system. The availability and security are provided, among others, by redundancy. It is presented by M-Canal out of N-Canal (MooN) architecture, the (N-M) indicates how many dangerous faults are possible, with-out the performance of the systems being impeded. An essential quantitative analysis based on the evaluation of the PFDavg is part to give high trust in the BMS. This paper will discuss how a quantitative method can be used to select the appropriate SIL according to shutdown system for Burner Management System (BMS). This system is a part of a safety solution that manages a combustion sys-tem; it allows the safe start-up operation, and the shutdown of multiple burner furnace section of a boiler, and main flame detection.
