Abstract
By means of a variety of analytical techniques, the combustion profile of vinyl chloride monomer (VCM) has been determined. This profile includes flame temperatures, soot content, and a combustion gas analysis. Depending on the amount of VCM-air premixing prior to combustion, the temperature of a VCM flame ranges from 950° to 1466°C. Similarly, the soot or unburned carbon content of a VCM flame varies from 3 to 6 weight percent. An analysis of the combustion gases from VCM reveal the following composition: HC1 27,000 ppm; CO2 58,100 ppm; CO 9500 ppm; phosgene 40 ppm; and VCM trace. From a hazard standpoint, the gross quantity of hydrogen chloride is the main source of danger in a VCM fire.
