More Information
Summary:The invention discloses a distribution type partial premixing jet device and a combustion chamber. The jet device comprises a hydrogen inlet pipe (1), a hydrogen distribution device (2), at least twohydrogen nozzles (3) and premixing pipes (5) with the number consistent with that of the hydrogen nozzles. The hydrogen distribution device (2) is of an end-to-end structure with a cavity in the center. The hydrogen inlet pipe (1) communicates with the inner cavity of the hydrogen distribution device (2). The hydrogen nozzles (3) are evenly distributed and mounted along the axis of the inner cavity of the hydrogen distribution device (2) and are communicated in a through manner. Each premixing pipe (5) comprises a straight barrel segment and a flaring segment, each straight barrel segment is arranged on the outer portion of the corresponding hydrogen nozzle (3) in a sleeving manner, it is guaranteed that each straight barrel segment and the corresponding hydrogen nozzle (3) are coaxial through a supporting piece (
