Title:
二元燃料注入装置を備えた低NOx型燃焼器
Document Type and Number:
Japanese Patent JP4040156
Kind Code:
B2
Abstract:
In a dual fuel injection system for a low Nox combustor, separate gaseous 43 and liquid 44 fuel manifolds are integrally joined to form manifold assemblies. Each manifold assembly extends circumferentially around the inlet of an annular fuel and air mixing passage (23-26)(Fig.1). The gaseous fuel manifolds have a number of gas discharge ports 49 spaced around their circumferences. The liquid fuel manifolds have a number of fuel nozzles 45 spaced around their circumferences. The gaseous fuel discharge ports and liquid fuel nozzles are oriented so as to inject fuel into the annular passages (23-26) in a manner that will facilitate mixing of the fuel and air. Separate gaseous and liquid fuel supply tubes are connected to each manifold.
