Principal Technology's modern burner management systems (BMS) are designed for the retrofit of legacy boilers, ovens, furnaces and other fired equipment used in the process industry. Based on a modular platform, Principal’s BMS meets all applicable modern standards for safe burner management and operations. Basic BMS modules offered by Principal Technology include burner safeguards, single burner ignition, multiple burner ignition sequencing, flame detection and optional pre-ignition combustible gas detection and process control. Additional modules are available to convert legacy natural draft systems to forced draft and add combustion control to improve reliability and operational efficiency. Principal Technology’s modular approach creates a custom BMS by applying particular modules to the application as needed.
