Example of piloted ignition
WebPiloted ignition Often combustion is initiated in a mixture of fuel and oxidizer by a localized source of energy. This source might be an electric arc (or spark) (moving charged particles in a fluid or a plasma) or a small … WebIn this work, the effect of seven different sample orientations from 0° to 90° on pilot and non-pilot ignition of PMMA (poly(methyl methacrylate)) exposed to radiation has been studied with experimental and numerical methods. Some new and significant conclusions are drawn from the study, including a U-shape curve of ignition time and critical mass …

It is intended to be used in conjunction with the Engineering Guide: Assessing Flame Radiation to … Web12. Each pilot must be equipped with at least one dedicated means of ignition as per clause 18.8.1 Note: Commonly employed ignition systems include: spark ignition at pilot tip, spark ignition of a portion of the pilot gas/air mixture prior to the pilot tip, compressed-air flame-front generator, inspirating flame-front generator. 13.
Webproposed criterion that piloted ignition would occur is when the mass flux m" of pyrolysates releasing from the surface (i.e. mass loss rate of the sample) reaches a value of 2.5 gm-2s-1. By following Bamford et al., the values of mass loss rate of the sample produced by thermal decomposition under piloted ignition conditions WebPiloted Ignition Go to video file-----NOTES.
