catalytic ignition catalytic ignitionA type of reheat ignition system. The catalytic igniter consists of a platinum or rhodium element in a case fitted into housing secured to the burner hub. Fuel flows to the mouth of a venturi tube that is open to a gas stream from the turbines, and the fuel-air mixture is sprayed onto the elements of the igniter. The chemical reaction lowers the flash point of the mixture sufficiently for spontaneous ignition of the mixture. |
