MHI ready to transition 320 MW J-Series GT from test-bed to market

MHI ready to transition 320 MW J-Series GT from test-bed to market
Mitsubishi Heavy Industries (MHI) has completed development of its J-Series gas turbine, Which delivers the highest output and thermal efficiency of any GT engine.
  The company plans to move quickly to begin marketing the new GT,with
first deliveries expected as early as 2011.
  The 60 Hz J-Series turbine has a rated power output of320 MW (ISO basis)in simple cycle operation.In addition, production versions of the J turbine has a rated power output of 320 MW (ISO basis) in simple cycle mode and 460 MW in combined cycle operation.In addition,production versions of the J turbine will enable thermal efficiencies in excess of 60% in combined cycle configurations.
  Mitsubishi's J-Series builds on the best elements of the company's G turbine technology, which has continued to evolve through successive modifications and materials and design improvements for over a decade.
  In addition, the J turbine benefits from both leading-edge computer enginerring capabilities and technology advances that have been achieved as a result of Japan's goverment-sponsored initiative to develop ultra-efficeient engines that operate at inlettemperature above 1,700 C
  With the adoption of low-thermal-conductivity TBC (thermal barrier conating) technology and improvements in cooling efficiency, the J-Series gas turbine is able to operate at inlet temperature approaching 1,600 C-100 degrees higher than the current-generation G units.
  In addition, enhanced three-dimensional design techniques have eanbled Mitsubishi to further improve turbine aerodynamics and increase compression ratio.
  According to Mitsubishi, increased out put and enhanced fuel efficiencies are only part of the story. As a result of its highly effieient combustion design- which retains the steam-cooling technology originally developed for Mitsubishi's G turbinges the
J enine also offers exceptional environmentl performance. Nox reduction form commercial J units is expected to equal the top of the line Gs, while Co2 emissons will be fully 50% less than a same-rated conventional coal-fired power plant.
