Abstract

Abstract

The main factors which influence ignition performance of igniter tube with large ratio of length to diameter and consolidated charge were compared by simulation with the calculation program, and the ignition performance was analyzed in different construction parameters and charge conditions. The influence law is summarized on construction parameters and charge conditions of igniter tube by analysis of the results. The diameter of fire hole, the height of the first hole, the hole area in unit length and charge density evidently effect on the ignition pressure and ignition characteristics. The diameter of fire hole, the height of the first hole, the hole area in unit length are the primary influencing factors of decompressing velocity after the diaphragm breaking, and the charge density effects on the permeability of charge bed and free movement of flame propagation. All of four factors evidently effect on the safety, the transient characteristics and the conformance of ignition.
