Title (EN) DUCTING ARRANGEMENT IN A COMBUSTION SYSTEM OF A GAS TURBINE ENGINE
(FR) AGENCEMENT DE CONDUITS DANS UN SYSTÈME DE COMBUSTION D'UNE TURBINE À GAZ
Abstract:
(EN) A ducting arrangement (30) in a combustion system of a gas turbine engine is provided. The ducting arrangement may be formed by duct segments (32) circumferentially adjoined with one another to form a flow duct structure (e.g., a flow-accelerating structure (34)) and a pre-mixing structure (35). The flow duct structure is fluidly coupled to pass a cross-flow of combustion gases. The pre-mixing structure (35) may include an array of pre-mixing tubes (48) fluidly coupled to receive air and fuel conveyed by a manifold (42) to inject a mixture of air and fuel into the cross-flow of combustion gases that passes through the flow duct structure. The duct segments or the entire ducting arrangement may be formed as a unitized structure, such as a single piece using a rapid manufacturing technology, such as 3D Printing/Additive Manufacturing (AM) technology.
(FR) L'invention concerne un agencement de conduits (30) dans un système de combustion d'une turbine à gaz. L'agencement de conduits peut être constitué de segments de conduit (32) circonférentiellement adjacents les uns avec les autres pour former une structure de conduit d'écoulement (par exemple, une structure d'accélération de débit (34)) et une structure de prémélange (35). La structure de conduit d'écoulement est en communication fluidique pour passer par un écoulement transversal de gaz de combustion. La structure de prémélange (35) peut comprendre un réseau de tubes de prémélange (48) en communication fluidique pour recevoir l'air et le carburant amenés par un collecteur (42) pour injecter un mélange d'air et de carburant dans l'écoulement transversal de gaz de combustion qui passe par la structure de conduit d'écoulement. Les segments de conduit ou la totalité de l'agencement de conduits peuvent se présenter sous la forme d'une structure unitaire, telle qu'une pièce unique utilisant une technologie de fabrication rapide, telles que la technologie de l'impression 3D/fabrication additive.
