The Korea Institute of Machinery and Materials (KIMM) has unveiled a hydrogen co-firing combustor for gas turbines used in power generation.
Hydrogen is highly reactive fuel which increases the risk of high temperatures and flashback, which is where the flame propagates upstream against the gas stream.
In order to prevent such risks, KIMM improved a fuel injection method which was then applied to heavy-duty gas turbine. It suppressed instability of the combustion to the same level of the original gas turbine while burning a mixture of 30 per cent hydrogen fuel.
While developed in South Korea, the new combustor needed to be transferred to the German Aerospace Center in Cologne for testing.
