摘要： PURPOSE:To eliminate an inconvenience in a combustion method of a combustion device having a fuel/air premixing nozzle, the inconvenience being such that the length of a flame is changed with a change in a combustion rate due to a change in fuel concentration of premixing air and as a result combustion vibration is produced. CONSTITUTION:A neutral fluid 8 not including fuel is supplied between premixing air 2 formed by being injected from a premixing nozzle 1 and high temperature gas circulated and staying in a downstream area of a premixing nozzle outlet part where a flow passage for the premixing air 2 is rapidly expanded.

摘要： PROBLEM TO BE SOLVED: To provide a cooling structure capable of reducing NOx in a gas turbine combustor.
SOLUTION: The gas turbine combustor comprises a heat chamber wall surface having a cooling passage through which the cooling air flows, inside of a double wall structure. The cooling passage is opened at a main cooling air supply opening formed at a side of a combustion region. The cooling air supplied from the main cooling air supply opening is guided in the direction along an inner wall surface by a guide member. As the cooling air flowing in the cooling passage inside of the wall surface is reutilized in cooling a film along an inner wall surface, the cooling air can be saved. Thus the air supplied from the compressor can be utilized more as the air for combustion, and NOx can be reduced.
