BURNER DEVICE, GAS TURBINE ENGINE, AND COGENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a burner device capable of reducing pressure loss in supplying a fuel gas to a flow channel for combustion, and having superior mixing performance of the fuel gas and air.

SOLUTION: This burner device in which the fuel gas G is supplied to a channel A1 for main combustion and a channel A2 for pilot combustion for burning, includes a mixing accelerating member 36 with which the fuel gas G jetted from a first supply opening 5 for supplying the fuel gas G into the channel A1 for main combustion, is collided so that the collided fuel gas G is diffused in the channel A1 for main combustion.
