Question 27Gas Turbine - Assistant Engineer
70% to passWhere are the carbon dioxide nozzles located in the GE LM2500 gas turbine enclosure?
AAbove and below the combustor section
BOn either side of the PT
CAbove the compressor
DOn the cross beam under the compressor front frame
AI Explanation
The correct answer is D) On the cross beam under the compressor front frame. The carbon dioxide (CO2) nozzles in the GE LM2500 gas turbine enclosure are located on the cross beam under the compressor front frame. This is the standard placement for the CO2 fire suppression system in this type of gas turbine enclosure to ensure effective coverage and distribution of the CO2 agent in the event of a fire. The other answer choices are incorrect because: A) the CO2 nozzles are not located above and below the combustor section, B) they are not on either side of the power turbine (PT), and C) they are not above the compressor.
