GPB70:


Kawasaki GPB 70 is 6.8MWe open cycle, single shaft type gas turbine which comprise of 12 stage axial flow compressor and 4 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, six can combustion system.  There are 2 types of model for this series which is  GPB70 (conventional diffusion) and GPB70D (dry low emission) . The applicable fuel for GPB70 is Natural Gas and Diesel Oil. Alternatively, the GPB70 series can be operated on dual fuel system.
