Study on Fire Characteristics of Horizontal Jet Fire of Heavy Oil
摘要
Abstract
In order to study the evolution of the fire characteristics of the horizontal jet fire of high tem-perature heavy oil,the horizontal jet fire test was car-ried out under different jet pressure and nozzle diame-ter.Image recognition technology was used to process the flame combustion video,and the flame horizontal projection distance and flame height were extracted.The results showed that the sensitivity of horizontal projection distance decreased with the increase of jet pressure and nozzle diameter.When the nozzle diam-eter was large and the injection pressure was in-creased,the suppression stage of the flame height would arrive earlier than that of the small nozzle di-ameter,and the suppression effect of the flame height would be more obvious.The prediction model of flame horizontal projection distance and flame height established by Allometricl equation and second-order polynomial function equation had R2 higher than 0.8,which can realize effective prediction of both.关键词
