GPB70/70D (6.5MW Class)


Ideal for reliable on-site base load power generation requiring from 5.5 MW to 6.5 MW for co-generation applications.
The GPB70/70D is based on Kawasaki's proven M7A heavy duty industrial gas turbine with over 15 years of commercial experience and proven reliability.  At 6.7 MW (ISO), it is ideal for cogeneration applications in offshore oil platforms, industrial process plant applications, hospitals, universities / colleges, prisons, district energy systems, life-science and bio-science facilities, and other facilities with large thermal and electrical loads.  The Kawasaki Industrial Gas Turbine Generator Unit provides the benefit of a large thermal capability to provide a co-generation system efficiency of 80% and a long service life of 32,000 EOH between overhauls.


A Closer Look


The GPB70D is suited for geographic areas requiring emissions control, with NOx emissions of 25 ppm (O2=15%) and CO emissions of 50 ppm (O2=15%) from 70-100% load, using Kawasaki's multiple nozzle DLE (Dry Low Emissions) fuel injection combustion system.
