Product: FlameHawk® Flame Detector
Forney’s FlameHawk® fiber optic flame detector is a dual channel solid-state device designed for
industrial and marine gas turbines.
The FlameHawk® fiber optic flame detector is a dual channel solid-state device designed for direct replacement of Geiger-Mueller (GM) tube flame sensors used on industrial and marine gas turbine engines.
The FlameHawk flame detector improves performance and reduces maintenance costs. It has durable fiber optic cables that transmit the spectral energy from the combustion process to the electronics module. This allows for remote mounting of the electronics outside of the engine enclosure, which eliminates complicated and costly cooling systems common in other flame sensors.
The FlameHawk flame detector system works in low NOx combustors, multiple fuel applications and with systems incorporating steam injection.
Operational Principles
The fiber optic cables and optical probes offer easy installation and maintainability. Simple threaded connections are used throughout the system to allow for rapid installation without the need for special tooling.
Unique features, such as a quick-release clamp on the frame engine optical probe, have been incorporated to
ease cleaning and inspection.
