BURNERS HAVING FUEL PLENUMS

摘要

Burners having a fuel plenum in a base are disclosed. One disclosed example apparatus includes a base of a burner, the base comprising a fuel plenum and coupled to fuel nozzles, where at least one of the fuel nozzles is in fluid communication with the fuel plenum. The disclosed example apparatus also includes a burner head of the burner comprising nozzle passages in fluid communication with an airflow path, where the burner head defines a pilot combustion space that opens towards a flame tube of the burner, and is in fluid communication with the airflow path, and where each nozzle passage is to receive a fuel nozzle to provide fuel to entrain with air from the airflow path.

主权项

1. A burner to produce heated gas, comprising:
a flame tube that may be coupled to a turbine and located in an air guiding device that encloses the flame tube and defines an airflow path; and a burner head coupled to a base comprising a body having a plurality of nozzle passages that fluidly communicate with the airflow path, wherein a fuel nozzle of a plurality of fuel nozzles projects into each nozzle passage to provide fuel mixed with air from the airflow path into the flame tube, wherein each fuel nozzle is fastened to the base, fluidly coupled to a fuel plenum formed in the base, and may be fluidly coupled to a fuel feed line, and wherein the burner-head body encloses a pilot combustion space that is open towards the flame tube and fluidly communicates with the air guiding device.
