摘要：

Effective thermal conductivity of coke was measured in the temperature range from 100-degrees-C to 1400-degrees-C by using the laser flash method. Effective thermal conductivity k of coke increased with a rise of temperature, and decreased with an increase of porosity of coke. The effect of radiation in the pore of coke on the value of effective thermal conductivity of coke was very small. The following equation was obtained for effective thermal conductivity k (W/m.K) as a function of temperature T (K) and porosity epsilon (-) of coke. k= {0.973+6.34 X 10(-3) (T-273)} (1-epsilon2/3)
