Fuel Control Retrofit: Reduced Costs, Enhanced Control

摘要

GE Marine reports that the US Navy has retrofitted nearly 50 LM2500 marine gas turbines with GE's Digital Fuel Control (DFC) kits. The LM2500s power the US Navy's CG-47 Ticonderoga class cruisers and DDG-51 Arleigh Burke class destroyers.rnThe DFC technology kits incorporate new controls for GE LM gas turbines - a technology now standard on new LM2500 and LM2500+ engines. Previous-generation LM2500s use a hydro-mechanical control system.rnNoting the benefits of the new system, the US Navy incorporated the DFC retrofit into a concurrent ship system modernisation programme. Since the first digital fuel controls were installed, the US Navy has accumulated more than 100,000 DFC operating hours on selected DDG-51 and CG-47 class ships. In addition, the US Navy recently purchased 16 DFC kits for four additional ships. GE anticipates continuing this modernisation programme throughout the above-mentioned ship classes.
