Development, Design and Verification
Mitsubishi believes achieving high reliability for long-term operation while at the same time pursuing targets such as
higher power generation capacity, greater efficiency and lower cost is one of the most important missions for the power
generation industry. Therefore, unproven design changes, which may involve high risks, should be avoided as much as
possible. Mitsubishi has a strong policy of undertaking thorough verification of new technologies prior to application. A
succession of proven design enhancements along with continual verification of new technologies represents the
fundamental basis of Mitsubishi Gas Turbines’ superior reliability.

Mitsubishi Gas Turbines: The Best Technology Available
Mitsubishi developed and put into operation the 1,200°C
class D-series gas turbines, the 1,400°C class F-series gas
turbines and the 1,500°C class G-series gas turbines.
Mitsubishi’s state-of-the-art proven technologies from the G
and J-series gas turbines are now being applied to upgrade
F series gas turbines. Technologies established through the
national project for a 1,700℃ class gas turbine are also being
incorporated into gas turbine upgrades. Additionally,
Mitsubishi’s advanced technologies can be tailored to meet the
needs of non-Mitsubishi gas turbine owners andoperators.

While maintaining proven features from the D-series,
F-series and G-series evolution, the most advanced
technologies in aerodynamics, efficient cooling air-flow and
metallurgy have been introduced into the J-series to increase
efficiency and reliability.

Mitsubishi provides a wide range of gas turbines, from 6MW
class to 400MW class, to meet the broad requirements of
customers around the world. We have designed,
manufactured and delivered more than 500 gas turbines.
Mitsubishi was the first to develop the world's most advanced
gas turbine, the J-series, with an inlet temperature of
1,600°C. Furthermore, Mitsubishi is pursuing a 1,700°C gas
turbine as part of the Japanese National Project, an initiative
supported by the Japanese government with the goal of
developing the most fuel efficient and highest output gas
turbine in the world. These state-of-the-art advances are not
just applied to new units, but are implemented at existing
plants to upgrade their operating capabilities.
Mitsubishi’s in-house plant combined with our Research & Development Center, allows for thorough, step by step testing
and verification. This is shown with our combustion system design, application, and verification. Today’s advanced
combustion systems rely on increasing temperature to achieve higher output and efficiency. Therefore, durable and
reliable hot parts such as turbine blades are essential. Mitsubishi has met this challenge by using innovative material
and structural designs. Reduction of metal surface temperature with the latest efficient cooling air-flow technology and
the introduction of new heat resistant materials allow the application of hot parts in this elevated operating temperature
environment. These applications are tested using a plasma spray coating test rig, high pressure combustion rig, low
speed research turbine, and a compressor rotor rig test before implementation in our in-house power plant, ensuring
verification in the lab and in the field.

Full Scale Verification and Operational Experience (T-Point)
Mitsubishi's in-house combined cycle plant, T-Point, enables real world application and testing of parts and systems.
Our gas turbine designs, including the J-series, are launched into the market only after concluding in-depth operational
verification at our facilities. Component tests and special measurements are performed at T-Point to ensure maximum
durability. Mitsubishi's commitment to thorough testing and verification of our products has made us an industry leader
in reliability.
