GAS TURBINE LIQUID FUEL ATOMIZER EMPLOYED RING

摘要

PURPOSE: A gas turbine combustor liquid fuel spraying apparatus having a ring is provided to include a ring in an internal side of a fuel spraying nozzle of a spray, to form a vortex while liquid fuel is passing the fuel spraying nozzle and to increase turbulent components in the liquid fuel, thereby improving fuel spraying performance of the spray. CONSTITUTION: A gas turbine combustor liquid fuel spraying apparatus having a ring includes a spray and a liner. The spray receives high pressure air from a compressed air supply pipe, receives liquid fuel from a liquid fuel supply pipe and atomizes the liquid fuel. The liner receives the high pressure air and atomized liquid fuel from the spray through a fuel spraying nozzle (310). The liner generates fuel gas by evaporating the atomized liquid fuel and combusts the fuel gas with the high pressure air after mixing the fuel gas and the high pressure air. The spray includes a ring (320) in an internal side of the fuel spraying nozzle in order to form a vortex while the liquid fuel is passing the fuel spraying nozzle.
