Various premixing burners have been investigated theoretically and experimentally for the operation with pure hydrogen. Peclet number calculations have been applied for the design. The investigated pore diameters for various preheating temperatures of the gas mixture and for stoichiometric mixture have been considered as subcritical. A flashback-free operation of the burner could be demonstrated for a gas speed higher than 12 ms(-1). Stable operation performance of the premixing burner for pure hydrogen could be achieved.
