Document Type and Number:
Japanese Patent JP2011117637
Kind Code:
A
Abstract:

To facilitate piping works by omitting piping for supplying cooling air to a part to be cooled and by simplifying a structure for supplying the cooling air, and to downsize a burner device for many kinds of fuels by reducing an occupied space of the structure for supplying the cooling air.

The burner device for many kinds of fuels is equipped with: a hollow cylindrical nozzle opening toward a throat 4; a burner support 29 provided to close an anti-throat end of the cylindrical nozzle; and a rod-like burner nozzle 34 penetrating the burner support in parallel with an axis of the cylindrical nozzle. The burner device is supplied with combustion air from the cylinder nozzle, and the burner support has a multilayered structure in the axial direction, and at least one layer has airtight hollow chambers 32, 33. The hollow chambers are connected to a cooling air source. Cooling air 44 is supplied from the hollow chambers to the part to be cooled of the rod-like burner nozzle.
