Due to the expansion of energy consumption and concern of environmental protection lead to the consideration of energy utilization for compensating fossil fuels which are the primary energy source. The main advantages of lingo-cellulosic biomass as a renewable source are that they provide various forms of energy such as heat, electricity and transport fuel. Coal and biomass co-firing had been studying widely in pyrolysis, gasification and oxidation processes, which played significantly for direct reduction of CO2 emission from fossil fuels. [1-3]

Vuthaluru [1] studied thermal behavior of collie sub-bituminous coal from Western Australia and biomass (wood waste, wheat straw) co-pyrolysis. The results showed three thermal events which were identified during pyrolysis. First and second stages were dominated by biomass pyrolysis and third stage was coal pyrolysis. During co-pyrolysis, Thermogravimetric curve (TG curve) displayed no interaction between sub-bitumen and biomass.
