The world's largest-class high efficiency two-shaft gas turbines

The H-100 Series gas turbines were developed for utility customers and industrial customers in both 50 Hz and 60 Hz regions. The first unit came into commercial operation in 2010.

Then Mitsubishi Hitachi Power Systems (MHPS) continued its efforts to improve the design of the H-100 Series gas turbines. While incorporating advanced elemental technologies and material technologies verified with the H Series gas turbines, we are continuously working to improve performance.

Overview

H-100 Series units are the world's largest capacity two-shaft gas turbines based on a great deal of experience in manufacturing gas turbines and achievements in the development of the H-25 and H-15 Series.

They achieve high efficiency as part of combined cycle plants with heat recovery boilers, co-generation systems or other combined cycle power plants.

The H-100 Series features simple cycle gas turbine output of 105 MW to 118 MW and an output range of 150 MW to 340 MW in combined cycle. As two-shaft gas turbines, they are suited to mechanical drive applications.

Features

  • Heavy duty design: A heavy and highly reliable structure designed in consideration of ease of maintenance and long-term continuous operation
  • High efficiency: High performance in various power generation cycles (simple, combined and co-generation)
  • Package type: Easy to carry and install
  • The series is applicable not only for power generation but also for mechanical drive.

Replacing worn gas turbines with H-100 Series ones will result in reduced nitrogen oxide (NOx) and carbon dioxide (CO2) emissions as well as lower fuel consumption after improvement of plant efficiency.

Replacement of gas turbines paves the way for making the most of existing plant equipment and it is applicable not only for simple cycle plants but also for combined cycle plants.
