LM6000

The LM6000 industrial gas turbine, which derives from General Electric's CF6-80 aircraft engine, is used in a variety of power generation applications. MTU has been providing maintenance services for this type of gas turbine since 1996.

The LM6000 turbine consists of a five-stage low-pressure compressor (LPC), a fourteen-stage high-pressure compressor (HPC), an annular combustor, a two-stage high-pressure turbine (HPT), and a five-stage low-pressure turbine (LPT). Unlike the LM2500 and the LM5000 this industrial gas turbine does not have an aerodynamically coupled power turbine which means that the low-pressure turbine drives both the low-pressure compressor and the generator.

GE has developed two enhanced versions of the LM6000: the LM6000 PG with single annular combustor (SAC) and its dry low emissions (DLE) equivalent, the LM6000 PH. As a risk- and revenue-sharing partner MTU holds a 13-percent stake in the LM6000 and the two derivatives. The LM6000 PG and LM6000 PH deliver 25 percent more power and 18 percent more exhaust gas energy for combined cycle or cogeneration operations than their predecessors. The efficiency has been markedly increased to reduce fuel consumption and emissions.
