GAS TURBINE PREMIXING CHAMBER

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine premixing chamber wherein required additional fuel is sharply reduced, emission of pollutants is hereby suppressed to the minimum and simultaneously a main flame is stabilized over a certain time interval. SOLUTION: At least one compressor coupled with a turbine is provided, and a premixing chamber 10 for a gas turbine of the type of including a combustion chamber includes a convergence section 12 positioned to cause combustion to occur therein. In order for the premixing chamber 10 to form a series of pilot flames adequately adjust to stabilize a main flame prepared in the combustion chamber, a plurality of pipes 19 are provided which have a hole 20 communicating said combustion chamber frontally of the premixing chamber 10. The convergence section 12 in the premixing chamber 10 has at least one circular groove 28 provided in the hole 20 belonging to the pipes 19.
