Abstract
The present invention provides a flexible hose for connecting a fuel manifold to a burner of a gas turbine engine. The flexible hose includes a metal convolute tube, an elongate member or members located in grooves formed in the inner surface of the convolute tube, and a pressure-containing sheath outside the convolute tube. The flexible tube has end connectors fluidly-tightly joined to respective ends of the hose for connection at one end of the hose to the fuel manifold of the gas turbine engine, and at the other end of the hose to the burner of the gas turbine engine.
Claims8
A method comprising:
- operating a gas turbine engine combustion apparatus that includes a fuel manifold, a plurality of burners, one or more combustors, and a plurality of flexible hoses, the burners being connected to the manifold by the respective flexible hoses, wherein the burners receive fuel from the manifold via the flexible hoses and direct the received fuel into the one or more combustors, each flexible hose including a metal convolute tube having grooves formed on an inner surface thereof;
- an elongate member or members located in the grooves;
- a pressure-containing sheath disposed outside of the convolute tube;
- and end connectors fluidly-tightly joined to respective ends of each hose for connection at one end of each hose to the fuel manifold, and at the other end of each hose to the burner;
- and
- causing each elongate member to vibrate within the metal convolute tube and independently of the metal convolute tube so as to actively disperse particulate matter that accumulates within the metal convolute tube.
