FLUID DISTRIBUTOR, BURNER DEVICE, GAS TURBINE ENGINE, AND COGENERATION SYSTEM

摘要

A fluid distributor (4) comprising a first feed port (5) for feeding fuel gas (G) into a main fuel flow path (A1), a feed path (6) for feeding the fuel gas (G) inside a gas flow path (A3) to the first feed port (5), and distributedly feeding means feeding the fuel gas (G) distributedly into a pilot fuel flow path (A2) so as to increase the distribution ratio of the fuel gas (G) to the first feed port (5) according to an increase in an overall feed flow rate of the fuel gas (G) from the gas flow path (A3) to a feed path (6) and, inversely, to decrease the distribution ratio of the fuel gas (G) to the first feed port (5) according to an decrease in the overall feed flow rate; a plurality of fluid distributors (4) being disposed in the main fuel flow path (A1) and pilot fuel flow path (A2) distributedly in the peripheral direction to constitute a gas feed means.
