Abstract


The indigenous coal is not being used in cement industries due to low-quality constraints. In Pakistan, coal blending is not being generally practiced yet. This research we utilize the Sor Range coal as a partial substitute of Indonesian coal by carrying out coal blending to meet the quality requirements of cement industries. In order to optimize the coal blending ratio, Indonesian coal was mixed with Sor-Range coal and blends were made. Using proximate analysis, coal parameters such as moisture, volatile matter, ash and fixed carbon were determined. Calorific value and sulphur content were determined by using Oxygen Bomb Calorimeter and Carbon-Hydrogen-Sulphur Determinator (CHS-580) respectively. Experimental results of ash, moisture, fixed carbon, volatile matter and heating value of Sor-Range coal meet the required coal quality except the Sulphur value. On the basis of laboratory testing results it was found that the Sor-Range coal is unsuitable to be used for the cement industries, due to the presence of high Sulphur content. It is found that all blended ratios meet the required specification of cement industries except blend-1 and blend-2. The optimum blend percent ratio is 80:20 i.e. 80% Indonesian coal (imported coal) and 20% Sor-Range coal (local coal). The final outcome is the financial saving by minimizing the import of foreign coal.
