A Fire Detection System Fault Treatmentof 9E Gas Turbine
There is a case of some 9E gas turbine trip which is caused by the fire detection fault.This article analyses the fire detection system of a gas turbine, and presents the fault phenomenon.In addition, it proposes some measures such as adding a cooling water pump to the fire detection, using the new lens and the fire detector produced by GE company whose detection system is separated, and changing the three air exhaust valves of the cooling water main pipe which belongs to the fire detection system outside the cover of the turbine room.By analyzing and processing the fault, we conclude that we should ensure the right logic action and also need to consider the environment and climate, installation process where the control equipments are located, which will contribute to find out the trouble early and nip it in the bud.Thereby, the operation reliability of the unit can be effectively improved.
