本文从理论和实验两方面研究了火把在对流气流中上升和在风中前进时的燃烧特性和飞行轨迹。研究表明，随着燃烧剂的燃烧，燃烧剂的飞行轨迹会不断减小。几种类型的风洞已经开发出来，专门设计用于研究燃烧剂在其最终下落速度下的燃烧。研究还表明，在恒定风速下，引火物的燃烧。研究了燃烧板的初始尺寸、初始形状、木材种类、初始含水率等因素对燃烧效果的影响，以及几种对流柱结构对燃烧效果的影响。这些研究的结果，使计算的最大范围内可能的火灾蔓延的给定的初始特性，一旦对流以上的火灾被称为水平风条件。
A theoretical and experimental study has been carried out on the combustion properties and flight paths of firebrands when they are carried upwards by convective currents and then forwards by the winds. The study has shown that the flight paths of firebrands can be fall decreases continuously as the firebrand burns. Several types of wind tunnels have been developed especially designed to study combustion of firebrands at their final velocity of fall. The study has also show that combustion of firebrands at constant wind speed. The influence of the initial size and initial shape of the firebrands, kind of wood and initial moisture content has been studied, as well as the influence of several types convection columns configurations. Results of these studies enable the calculation of the maximum range of possible fire spread by firebrands of given initial characteristics, once the convective currents above the fire are known as vell as the horizontal wind conditions.
