Document Type and Number:
WIPO Patent Application WO/2023/243434
Kind Code:
A1
Abstract:
A hydrogen combustor according to one embodiment of the present invention comprises at least one fuel injector module and a hydrogen supply pipe. The at least one fuel injector module is configured by forming a module from a plurality of fuel injectors. The fuel injectors each comprise: an air introduction pipe that has a swirler for causing air to swirl; a hydrogen injection pipe that injects gaseous hydrogen approximately perpendicularly to the air swirling through the swirler such that the hydrogen collides with an inner wall of the air introduction pipe; and a flame stabilizing part that expands a flow path of a mixed gas of the air and the hydrogen stepwise. The hydrogen supply pipe supplies hydrogen by dividing a plurality of supply systems to the hydrogen injection pipes of the plurality of fuel injectors constituting the fuel injector module.
