Flame Detection Gas Turbine

Flame Detection Gas Turbine Points : Flame Detection Gas Turbine Power Plant The flame detection consists of two detectors per combustion system. The non regenerative units have two detectors, regenerative units have four. Flame detectors are utilized both in the startup sequence and during starting. As soon as one detector per system detects flame, the starting system is allowed to proceed, conversely, a failure of only one detector will allow the unit to continue to run but will alarm. With both detector detecting loss of flame, the unit is immediately shut down. The fast response of flame-out detection is particularly important on machines having exhaust fired equipment, but also on exhaust recovery equipment due to possible accumulation of explosive mixtures opens, shorts, and ground arc alarmed similarly to the vibration system.
