Numerical Redesign of 100kw MGT Combustor for 100% H2 Fueling

The use of hydrogen as energy carrier in a low emission microturbine could be an interesting option for renewable energy storage, distributed generation and combined heat & power. However the hydrogen using in gas turbine is limited by the NOx emissions and the difficulty to operate safely. CFD simulations represent a powerful and mature tool to perform detailed 3-D investigation for the development of a prototype before carrying out an experimental analysis. This paper describes the CFD supported redesign of the Turbec T100 microturbine combustion chamber natural gas-fired to allow the operation on 100% hydrogen.
