ATOMIZER, COMBUSTION DEVICE INCLUDING ATOMIZER, AND GAS TURBINE PLANT

摘要

PROBLEM TO BE SOLVED: To provide a spray nozzle capable of expediting atomization of spray fluid and suppressing the abrasion caused by solid contents in the spray fluid, and to provide a combustion device equipped with the spray nozzle.;SOLUTION: A spray nozzle comprises: an internal mixing chamber 27; spray fluid flow channels 23, 24 supplying spray fluid 11 to the internal mixing chamber 27; spray medium flow channels 29, 30 supplying a medium 12 for spray to the internal mixing chamber 27; an outlet hole 41 spraying a fluid mixture 13 of the spray fluid 11 and the medium 12 for spray; and fluid mixture flow channels 31, 32 connecting the internal mixing chamber 27 to the outlet hole 41. The fluid mixture 13 flowing in the fluid mixture flow channels 31, 32 joins at a confluent part 35 and is sprayed from the outlet hole 41. The internal mixing chamber 27 has an intermediate injection hole 26 which sprays the spray fluid 11 into the internal mixing chamber 27. The intermediate injection hole 26 is provided at the confluent part 25 of the spray fluid flow channels 23, 24. The spray fluid 11 flowing in the spray fluid flow channels 23, 24 joins at the confluent part 25 and is sprayed from the intermediate injection hole 26.;COPYRIGHT: (C)2016,JPO&INPIT
