O2/CO2气氛下乙烷可燃极限的实验研究和计算.

The flammability limit is an important parameter of combustion characteristics. In this paper, a flammability limit experimental device was set up based on the 5L cylindrical reactor. The flammability limits of ethane under CO2/O2 atmosphere were studied and compared with those in air atmosphere. The results showed that high concentration of CO2 reduces the upper flammability limit and increases the lower flammability limit of gas mixture. The influence of high concentration of CO2 on flammability limit was analyzed. The formula of calculation of flammability limit for CO2/O2was deduced according to the thermal theory. The average absolute deviation between the experimental values and calculated values is within 2.2%. The values of calculation are in agreement with the experimental data. [ABSTRACT FROM AUTHOR]
