Industry: Power
Business Area: Engineering Design Review – Burner Management System (BMS)
Background:
A major Power producer located in Middle-East was building a new green field power plant (2640 MW) with boiler fuel being Heavy Fuel Oil, Heavy Crude Oil. As part of engineering integrity validation, a third party certification major was contracted for design review and certification.
Business Objective:
Design Review for Safety of Burner Management System for Boilers, as per NFPA-85 standard.
Solution:
Design review of the safety of burner management system for Boilers, as per NFPA -85 Boiler and Combustion Systems Hazards Code Edition 2011.
