COMPARISON OF PHYSICAL PROPERTIES OF FINER GRAINS OF CALCINED COKES GENERATED DURING CALCINATION WITH THOSE ORIGINALLY PRESENT IN GREEN COKES

摘要

Green coke is an aggregate of various grain sizes ranging from few microns to few inches. The finer particles present in green cokes are more susceptible to burn inside the kiln or get drifted outside the kiln along with combustion gases. Simultaneously finer particles are generated inside the kiln during the calcination process because of intense heat and abrasion during transportation from feed end to discharge end of the kiln. Now, Goa Carbon Limited has tried to find out whether the generated finer grains of calcined coke differ from originally present finer grains in physical characteristics. There are indications that the generated finer grains are significantly denser than originally present finer grains as seen from bulk density, apparent density etc.
