Multi-cyclone air inlet head structure of hydrogen-doped fuel gas turbine

The invention provides a multi-cyclone air inlet head structure of a hydrogen-doped fuel gas turbine. After a gas compressor, one part of airflow flows in through the center two-stage cyclone, one part of hydrogen-doped fuel flows in through the fuel straight channel, airflow flowing out of the first-stage straight blade stage separates cyclone airflow from the hydrogen-doped fuel, the cyclone airflow and the hydrogen-doped fuel are supplied to a combustion chamber, and stable flame in a non-premixed combustion mode is achieved. And meanwhile, the first-stage straight blade stage effectively delays the flame root position and widens the tempering boundary. The other part of the airflow flows in through eight annularly-distributed small cyclones, the other part of the hydrogen-doped fuel flows in through a fuel perforated straight channel, the hydrogen-doped fuel in each small cyclone is mixed with the airflow through a straight hole in the fuel perforated straight channel and a contraction channel and supplie
