Abstract


Pakistan, an agricultural country having biomass and proven coal reserves can use this innate energy resource. Proximate analysis which includes ash content, volatile matter, fixed carbon, moisture content and Gross calorific value of different Coal samples from Gari Habib, Kotli, Chirag and Muzaffarabad Coal was carried out using ASTM standards. Similarly, proximate analysis of different type of biomass such as bagasse pith, saw dust, coconut shell and coconut waste was also determined. Concept of biomass blending was evaluated by using Heat balance method for checking the feasibility of biomass combination with coal. Saw dust and coconut shell giving high calorific value such as 4324.17 & 4065.83 K Cal was blended with Gari Habib coal as it contain least Ash content out of all other sample. The GCV of Gari Habib coal was determined for Heat balance method then blending of Gari Habib Coal with Saw dust and coconut Shell was done. The values obtained for saw dust& Gari coal were Coal70:sawdust30;54.85%:45.15%, Coal50:Sawdust50;34.22%:65.78%,Coal30:Sawdust70;18.2%:81.7%, similarly for coconut shell  blending ratios were 70:30, 50:50, 30:70 and we got these values 53.32%:46.67%, 32.84:67.16%, 17.30%82.70% respectively. Then proximate analysis of these blending ratios was compared with the previous proximate analysis carried out independently to mark the differences. The Blending process before combustion and growth rate of agricultural sector shows that it will effectively utilize biomass and save coal for future needs thus making it profitable, sustainable technology and environment friendly.
