Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a flame suppression system for protecting a multiple tube nozzle of a turbo machine combustion system. SOLUTION: The protection system for a premixing device (14) in a turbine (30) engine (2) includes a body (44) having an inlet part (46), an outlet part (52) and an outer wall (45), and collectively forming a fuel supply plenum, a plurality of fuel mixing tubes extending through at least a part of the fuel supply plenum, each having at least one fuel supply opening in fluid connection with the fuel supply plenum, and at least one temperature fuse (211) disposed on an outer surface of at least one tube (60) and including a material which melts upon ignition of fuel in at least one tube (60) and detours the fuel from the fuel supply opening to at least one bypass opening. A method and the turbine (30) engine (2) depending on the protection system are also provided. COPYRIGHT: (C)2010,JPO&INPIT
