Abstract
A method and a device for producing an ignitable fuel/air mixture includes a fuel fraction which is hydrogen or a gas mixture containing hydrogen and which is burnt in a burner arrangement for driving a thermal engine, in particular a gas turbine plant. An exemplary method includes combining a fuel flow and of an air flow, so as to form a fuel/air mixture flow, and providing a further air flow, catalyzing part of the fuel/air mixture flow, so as to form a partly catalyzed fuel/air mixture, during an exothermal catalytically assisted reaction of the fuel, the released heat of which is utilized at least partially for heating the further air flow, admixing the heated further air flow to the partly catalyzed fuel/air mixture, so as to form an ignitable fuel/air mixture, and igniting and combusting the ignitable fuel/air mixture.
