SYSTEM FOR FIXING A FLAME PIPE OR A LINER PLACED IN A COMBUSTION CHAMBER OF A GAS TURBINE WITH TWO CYLINDRICAL ELASTIC HEADS

摘要

PURPOSE: A fixing system for a flame pipe is provided to prevent the metal part of a combustion chamber from being scratched by a ceramic liner, and to reduce manufacturing and maintenance costs by removing or reducing tension from different thermal expansion coefficient between the liner of the combustion chamber and the contact part. CONSTITUTION: A fixing system for fastening a liner or a flame pipe(10) placed in a combustion chamber of a gas turbine for discharging low pollution level material is composed of two cylindrical elastic heads(5) fixed to the end of the flame pipe by wedge. One cylindrical elastic head is placed between a burner(3) and the flame pipe and the other cylindrical elastic head is positioned between the flame pipe and a flow conveyor(4). The cylindrical elastic head is composed of two parallel notches longitudinally arranged, and at least a ring shaped housing connected to the end of the flame pipe.
