A Novel 100% Hydrogen Gas Turbine Combustor Development for Industrial Use

Doosan is developing a 5 MW 100% hydrogen gas turbine combustor based on the existing NG (natural gas) firing combustor through a national project. This engine consists of 8 (eight) cans of the combustor and our plan is to develop a hydrogen burner to replace the existing NG burner, if possible, without any change of other combustor components such as liner & transition piece, etc. We developed various concept nozzles for 100% hydrogen combustion without flash back during the operating condition and low NOx emission using dry low NOx premixed combustion methods. Among the various concept nozzles several candidates conducted experiment test in ambient pressure condition which they showed low NOx emission and larger operating conditions through lean blow off and flame holding flash back test. The best nozzle will be selected and tested at ambient & high pressure can test for evaluating 100% hydrogen combustor development targets.
