WIPO Patent Application WO/2019/225382
Kind Code:
A1
Abstract:
A burner (7) characterized by being equipped with: a fuel supply nozzle (21) to which a mixed flow of a solid fuel and a solid fuel transport gas is supplied; a flow passage that is arranged on the outside of the fuel supply nozzle (21) and that supplies combustion air separated from the mixed flow; and ammonia supply nozzles (42) which are capable of supplying ammonia on the downstream side of the outlet of the fuel supply nozzle (21) toward a reduction region (53) in which oxygen in the transport gas has been consumed due to ignition of the fuel and the progress of combustion, resulting in a low oxygen concentration. Thus, it is possible to provide a burner capable of burning a mixture of a solid fuel and ammonia, and a combustion device equipped with this burner.
