  • Patent number: 6189321
    Abstract: A distributor for supplying burners of a gas turbine with fuel, air and coolant. Prior art distributors contain a combination of ring lines and tie lines, over which the fuel is distributed to individual burners. It is very complicated and expensive to replace defective components, and in some cases the entire apparatus has to be dismantled to do so. The distributor of the invention has two or more modules, depending on the number of burners, which are assembled from distributor units and regulating units in such a way that they can be taken apart again. For each burner, at least one regulating unit is provided, from which at least one supply line for the fuel, air and coolant extends to the burner.
