Special thanks are indebted to my supervisors Dr. M. Hamdan and Dr. Y. Khraisha, whom without their support, encouragement and advice, my work could have been infinitely more difficult . Also special thanks are indebted to my family, especially my father and my mother for their advice and encouragement . Also I highly appreciate the great assistance conducted through the mechanical engineering lab staff, computer center staff, industrial engineering department workship staff at the faculty of engineering and Technology. Also I highly appreciate the support ami great help given to me by Dr. M. Ilammad and AL-ICayyali Company for their help in providing live burner. The. Royal Scientific Society, especially Dr. Najclv Akeel for their help in carrying out the volumetric prod uct concentration analysis, and Jordan Electricity Authority for their help in providing information about oil shale. Finally, not to forget, the support and great help to me by ell my friends throughout my research. JLJL Abstract A ’coutant ’ carbon steel combustion chamber cooled by water jacket was constructed to burn tliescl fuel and mixture of shale oil & diesel fuels. During experimental work air fuel ratio was determined , temperatures were measured using Chrornel/ Alumel thermocouple, finally the gasous combustion product analysis was carried out using gas chromatograph technique. The constructed combustion chamber was operating satisfac tory for several hours of conliuous work. According to the measurements it was found that: the flame temperature of a mixture of diesel imd shale oil fuels was greater Ilian the flame temperature of diesel fuel, and the suiter emissions of a mixture of tliescl and shale oil fuels was liighcr than that of diesel fuel. Calculation indicated that the dry gas energy loss was very high and the incomplete combustion energy loss was very small.
