MICROSTRENGTH CHARACTERISTICS OF HIGH ASH COKE

Experiments were carried out to determine the microstrength of differe nt high ash coke samples obtained from 2 and 250 kg ovens. Microstreng th of coke is determined using small quantity of sample (50 m/) with s mall sample size (3-6 mm) and is an indicator of the inherent strength of the coke matter. The microstrength values obtained were then corre lated with the ash, VM/reflectance and fluidity of the parent coal and also conventional strength indices of coke like M10 and CSR. The corr elations obtained indicate that except in the case of very strong coke , correlation exists between microstrength, M10 and CSR values of coke .
