DEVELOPMENT OF AN AERODERIVATIVE GAS-TURBINE DRY LOW EMISSIONS COMBUSTION SYSTEM

This paper gives the development status of GE's new aeroderivative pre mixed combustion system. This system consists of a new fuel staged ann ular combustor, compressor rear frame, first-stage turbine nozzle, ele ctronic staging controller, and fuel delivery system. Component test r esults along with a description of the combustion system are presented . This new system will reduce NO(X) emissions by 90 percent relative t o the original aircraft engine combustion system while maintaining low emissions of CO and UHCs. Tests of a LM6000 gas turbine equipped with the new system are planned for early 1994.
