Abstract

Doosan is currently developing a 100% hydrogen gas turbine combustor with a micro-mixer concept multi-tube type nozzle, which has the ability to prevent flash-back phenomena during operation. This combustor is intended to replace the existing natural gas firing combustor for 5 MW, and has also been designed to achieve low NO_x emissions through the utilization of premixed methods. Our testing has shown that the nozzle provides an expanded operating range through lean blow off and flame holding flash back tests. Going forward, we plan to continue improving and testing the nozzle in real geometry under high-pressure conditions.
