Title:
ガス点火装置及び点火炎形成方法
Document Type and Number:
Japanese Patent JP4121096
Kind Code:
B2
Abstract:
An apparatus and method for establishing a stable pilot flame at a wide range of operating conditions, having a main fuel tube, an outer tube concentrically enclosing the main fuel tube, a swirler located downstream from the outer tube, an ignitor, and several fuel manifold tubes connected to the main fuel tube, are disclosed. The fuel manifold tubes direct a portion of the pilot gas fuel stream radially outward from the remainder of the pilot fuel. The axial momentum of the radially displaced fuel stream is greater than the average axial momentum of the remainder of the pilot gas streams. This relationship between the axial momenta of the gas steams promotes flame recirculation and stabilizes the pilot flame over a wide range of operating conditions.
