E&T: Hydrogen Combuster to Cut Emissions From Fossil Fuel Facilities

e&t logo

Scientists have developed a hydrogen combustor for gas turbines that could cut carbon emissions from fossil-fuel powered energy facilities.

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.
