Abstract

A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas-liquid spout portion, a gas introduction portion, a liquid inlet, a first gas inlet passage, a second gas inlet passage, and a spout. The first gas inlet passage is provided at at least one place of the annular gas introduction portion so as to communicate with the gas flow passage and the gas-liquid mixer, and allows a gas flow flowing through the gas flow passage to enter the gas-liquid mixer. The second gas inlet passage has a gas inlet having a predetermined area ratio, is provided on a downstream side of the first gas inlet passage of the gas introduction portion, and communicates with the gas flow passage and the gas-liquid mixer.
