  • System and method for high frequency acoustic dampers with baffles
    Patent number: 11174792
    Abstract: A rotary machine includes at least one burner including a front panel having a front side and an opposing back side. The acoustic damper includes at least one wall, at least one cooling air inlet, at least one outlet, and at least one baffle. The wall extends from the back side of the front panel and defines a dampening chamber. The cooling air inlet is defined within the back side of the front panel and is configured to channel a flow of cooling air into the dampening chamber. The outlet is defined within the back side of the front panel and is configured to channel the flow of cooling air out of the dampening chamber. The baffle extends from the back side of the front panel and is configured to reduce a velocity of the flow of cooling air within the dampening chamber.

  • COMBUSTOR WALL ELEMENT AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20180100652
    Abstract: A combustor wall element includes a wall having a front surface and a back surface. The front surface is provided on a front side of the wall and the back surface is provided on a back side of the wall. A through opening penetrates the wall from the front surface to the back surface. A duct is provided extending from the back surface and to a back end of the combustor wall element, and the duct is in fluid communication with the through opening. At least one cooling channel is provided inside the wall, wherein the cooling channel extends between a first open end and a second open end. At least a section of the cooling channel extends at least essentially parallel to the front surface.
