GPB300:


Kawasaki GPB300 is the 30MWe open cycle, twin shaft type gas turbine which comprise of 14 stage axial flow compressor and 2 stage axial turbines. The gas turbine generator set consists of gas turbine engine, engine control system, generator and the package auxiliary system such as reduction gear, coupling, and lubrication, starting and turning system. It is equipped with a dual ignition and eight can combustion system.  There are 2 types of model for this series which is  GPB300 (conventional diffusion) and GPB300D (dry low emission) . The applicable fuel for GPB300 is Natural Gas.
