Nowadays Pakistan is having a serious constraint on electricity shortage. Due to this growing lack of energy, the world has to change its appliances in such a way to move towards renewable resources and in this Coal is of significant importance. In this research work, we have focused on the thermal behavior of coals and also investigated the particle size of the indigenous coals and prepared a burning profile of these coal samples (Khushab, Lakhra, Thar, Makerwal, Kotli, Chamalang, Dukki and Sharig) by using Thermogravimetric method. The heating rates investigated in this study were 20^oC/sec, 30^oC/sec, 40^oC/sec and the particle size was kept 250μm (60#). In Air environment with a Medium flow rate under the holdup time of 10 min at 110^oC and for 20 min at 950^oC. It is clarified that the air atmosphere affects the weight loss, as the heating rates increased, the weight loss of samples was also increased and with the gradual increase in the temperature, it decreased the total burning duration. It can be concluded that Air environment and Heating rates have a positive effect on the combustion of coal. This study will help to make a burning profile of the indigenous coal and to reduce the emissions of SO_x and NO_x, as a result it could be easily found out that which coal is most suitable for use in the industrial use.
