Combustor cap assembly

摘要

A combustor generally includes a shroud that that defines at least one inlet passage extends circumferentially inside the combustor. A first plate extends radially inside the shroud downstream from the inlet passage. The first plate defines at least one inlet port, at least one outlet port and at least partially defines at least one fuel nozzle passage. The shroud at least partially surrounds a sleeve that extends around the fuel nozzle passage. A tube at least partially surrounded by the sleeve may extend through the fuel nozzle passage. The tube, the sleeve, and the first plate may at least partially define an outlet passage. A first fluid flow path generally extends from the at inlet passage to the inlet port, and a second fluid flow path extends generally from the outlet port to the outlet passage.

主权项

1. A combustor, comprising:
a. a shroud that extends circumferentially inside the combustor, wherein the shroud defines at least one inlet passage; b. a first plate that extends radially inside the shroud downstream from the at least one inlet passage, wherein the first plate defines at least one inlet port, at least one outlet port and at least one fuel nozzle passage; c. a sleeve at least partially surrounded by the shroud and that extends radially around the at least one fuel nozzle passage, wherein the sleeve extends from the first plate radially outward from the at least one fuel nozzle passage; d. a tube at least partially surrounded by the sleeve and that extends through the at least one fuel nozzle passage, wherein the tube, the sleeve, and the first plate at least partially define an outlet passage; e. a first fluid flow path from the at least one inlet passage to the at least one inlet port; and f. a second fluid flow path from the at least one outlet port to the outlet passage.
