Measurement of Dynamic Temperature Profile inside a Cigarette Combustion Coal with a Thermocouple

The gas temperature inside combustion coal of a burning cigarette was determined by a specially designed thermometer System with fast response micro thermocouples while the cigarette was puffed or smoldering under ISO smoking regime.The temperature distribution was displayed graphically with associate software.Based on temperature distribution at different points of time, the dynamic changes of temperature during smoking process were analyzed, the mechanism of air flow entering into the coal was further verified.
