IM270 Series

Since the very first jet engine of Japan was made back in 1945, IHI had produced more than 5000 jet engines. With the knowledges and technologies gained through the experiences over 60 years of operation in the field of aero-engines, resulted to introduce this IM270, which is the original gas turbine with low emission combuster type that has the highest reliability and performance in the world.

Features of IM270

1.Flexible heat and power conversion "IHI-FLECS", available.

When the demand for heat is small due to a change in the thermoelectric load of the user, excessive heat can be converted effectively to electric power by injecting excessive steam into the gas turbine.

2.High efficiency

IM270 is a simple cycle, one shaft gas turbine developed by IHI independently, and it has achieved a power generating efficiency of the highest level for this class, even without steam injection. With steam injection, the electric power output and power generating efficiency can be increased.

3.Compact System

Using IHI self-developed packaging (IPAC), minimum space is required for installation.

4.Low NOx concentration

As a lean premixed burner was adopted in IM270, it became a gas turbine with very low NOx emission, even without steam injection. With steam injection, NOx becomes even lower at the rate of 10 ppm (converted to 16% O2) with the maximum steam injection has been achieved.

5.Rich in experience, high in reliability

Structure made simple with fewer parts, and earning the trust of higher reliability by applying IHI´s dependable aero-engine technology to protect the exhaustible hot section.

6.Small vibration and noise reduction for the environment

Since gas turbine is the engine with circular motion with a minimal vibration which makes vibration measurement easily planned for temporary or/and foundation work and having high frequency makes the noise reduction for the better environment

7.Total low cost for the user

Overall functions of the plant have been reviewed, based on the fundamentals, to make standard specifications and optional specifications clear. As a result, it became possible to offer the optimum system with the minimal total cost for the user.
