Hydrogen Gas Turbine Combustion Technology

We are developing a hydrogen gas turbine combustion technology with the aim of establishing an environmentally friendly energy supply system that utilizes hydrogen as fuel.
Compared to the natural gas that is used as fuel for gas turbines, hydrogen tends to be more unstable due to its higher flame speed and to generate more NOx emissions due to its higher combustion temperature.
To overcome these problems, KHI is developing a combustor that reduces the effects of unstable combustion, such as flash backs, and realizes low NOx combustion through the use of miniaturized hydrogen flames.
To help establish this unique hydrogen gas turbine combustion technology, we are proceeding with its development while repeatedly performing combustion simulations and machine testing at RWTH Aachen University in Germany.
