Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen. The nozzle includes a cylindrical tube through which air and fuel flow, and the cylindrical tube has an inlet formed at a longitudinal end thereof for introduction of a first fluid (e.g., compressed air) into the cylindrical tube. The cylindrical tube has one or more supply ports formed on a circumferential surface of the cylindrical tube for introduction of a second fluid (e.g., fuel such as hydrogen) into the cylindrical tube. The cylindrical tube has at least one fuel/air separator disposed interior of the longitudinal end, the fuel/air separator operative to cause a flow of the second fluid to be sandwiched between two flows of the first fluid before the first and second fluids subsequently mix inside the cylindrical tube. The nozzle may be included in a combustor of a gas turbine engine.

Combustor nozzle, combustor and gas turbine including same

Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen. The nozzle comprised of a cylindrical tube is configured for introduction of a first fluid (for example, compressed air) and a second fluid (for example, hydrogen or a fuel containing hydrogen). Along an inner surface of the nozzle, one or more fluid vortex generators are disposed. As compressed air flows over the one or more fluid vortex generators, the compressed air swirls inside the nozzle resulting in a turbulent flow of the compressed air. As fuel is then introduced into the nozzle, the fuel encounters the swirling or turbulent flow of compressed air, and the introduced fuel is thoroughly mixed with the compressed air so that the fuel/air mixture will be combusted in a uniform manner. The nozzle may be included in a combustor of a gas turbine engine.

A fuel nozzle, a fuel nozzle module having the same, and a combustor having the same, which can solve a problem of combustion instability due to a high-frequency resonance generated by fuel containing hydrogen are provided. The fuel nozzle includes a fuel flow path through which a fuel flows, and a plurality of fuel plenums including a plurality of micro-mixers including a mixing flow path through which a fluid in which the fuel and compressed air are mixed flows and a fuel supply hole for supplying the fuel to the mixing flow path, wherein the plurality of fuel plenums are formed in the fuel flow path to be spaced apart from each other.

Fuel nozzle, fuel nozzle module having the same, and combustor

A fuel nozzle, a fuel nozzle module having the same, and a combustor are provided. The fuel nozzle includes a nozzle cylinder having a space through which fuel flows and a plurality of fuel holes through which the fuel flows in a surface, a shroud spaced apart from the nozzle cylinder and formed to surround the nozzle cylinder in a longitudinal direction of the nozzle cylinder, and a mixing flow path formed between the nozzle cylinder and the shroud to mix the fuel supplied through the plurality of fuel holes and compressed air supplied from a compressor.

The present invention relates to an inner cloth for a glove which is inserted between a lining material contacting with a user's skin and an outer skin exposed to the outside and includes a certain connection member for thereby being fixed together with a lining material and an outer skin based on a sewing operation, so that it is possible to implement good moisture penetration, anti-cold, and waterproof functions. The inner cloth for a glove includes a pair of hand-shaped panel members which each include a certain size or area and an edge portion connected at a certain width, and a connection member which is arranged at a certain position of the pair of the panel members and is integrally formed when the panel members are connected, and is formed in a certain shape. The glove implements good moisture penetration, anti-cold and waterproof functions using the inner cloth of the present invention.
