COAXIAL INJECTOR

摘要

The present invention relates to a coaxial injector provided to allow mixed injection of liquid and gas, comprising; a liquid injection pipe for flowing injection of a liquid; and a casing provided to surround the liquid injection pipe; while being provided with a mixing chamber inside the casing to mix the liquid injected from the liquid injection pipe with the gas with the mixing chamber being characterized by division with a partition wall made of a porous material separated from the outer periphery face of the liquid injection pipe. Hence, mixing and atomizing efficiencies at a spray center of the coaxial injector can be improved even if a flux of the liquid jet may be large.
