The coal Briquetting is one of the small scale technology to use the local coal for various applications. In the current study the coal briquettes were developed by using the coal of the Khyber Pakhtun Khwa province of Pakistan and their strength and thermal properties were evaluated. A small scale experimental unit was made locally for the formation of coal briquettes. Polyvinyl acetate (PVA) binder was chosen for making briquettes because of its good binding characteristics and its organic nature that helped in increasing the mechanical strength and the combustion characteristics of coal briquettes. Different briquettes of the same size and shape were formed by using changing the composition of PVA binder. The mechanical strength of coal briquettes was measured by compressing the Briquetting by applying external load on them until their breaking points. The load required and deflection produced by the briquettes at their yield and break points was found out and a comparison was made among briquettes to identify the high strength briquettes. The thermal properties were measured for all the briquettes by finding out their calorific value. The results show that the thermal properties and strength was the maximum for the briquette no 4 with a composition of 165 ml of PVA binder mixed with 220 ml of water as solvent in 1kg of coal in this work.&#13;
