Abstract
This liquid injection nozzle atomizes and sprays liquid, while reducing loss of kinetic energy, thereby promoting mixing between the liquid and a gas and thus promoting the reaction between the liquid and the gas. In the liquid injection nozzle, a plurality of distal end tips each having an injection hole are provided on a distal end portion of a nozzle body. Each distal end tip has a conical swirling flow chamber. A communication thin hole is formed in the distal end portion. The communication thin hole extends from a hollow chamber to the conical swirling flow chamber of the distal end tip. When the valve needle is lifted, liquid flows through the communication thin hole into the swirling flow chamber in a tangential direction and generates a vortex flow, and the vortex flow is sprayed from the injection hole.
