GAS TURBINE COMBUSTOR, CAPABLE OF IMPROVING IGNITING PERFORMANCE OF A COMBUSTOR EVEN IN LOW PRESSURE AND LOW TEMPERATURE ENVIRONMENTS

摘要

PURPOSE: A gas turbine combustor is provided to enlarge an ignition possible area by controlling a mixing rate of air and fuel to favorable for an ignition and to simultaneously reinforce the atomizing of a liquid fuel because an electromagnetic force is induced at a point where a fuel is sprayed by using a spraying controller.;CONSTITUTION: A gas turbine combustor comprises a fuel spraying unit(130), an ignition unit(140), and a control unit(160). The fuel spraying unit induces an electromagnetic force at a point where a fuel is sprayed into the inside of a mixing chamber, thereby changing a flow field of the sprayed fuel. The control unit controls the spraying unit so that a fuel distribution being formed by diluting the fuel and spraying has a form to be easily burned. The control unit controls the ignition unit to burn the fuel in the inside of the mixing chamber. The fuel spraying unit comprises a nozzle body(132) and an injection controller(136).;COPYRIGHT KIPO 2012
