Influence of process condition on test result of 40 kg coke oven
The 40 kg coke oven is a commo nly used device to evaluate the coking properties of coking coal.The influences of coking,coal preparation and quenching process conditions on the test results of the 40 kg coke oven were investigated by the orthogonal experiment.The results showed that the optimal coking process condition was initial and final coking temperature of 800℃and 1 050℃,respectively,and the holding time of 6 h;the optimal coal preparation process condition was 85%-90% coal with particle size＜3 mm,no higher than 30% coal with particle size＜0.5 mm,coal moisture of 10% and bulk density of 800 kg/m3;the optimal quenching condition was 13.5 kg consumption of quenching water and 5 minutes quenching time.
