Abstract
Furnaces of steel sheet combustion chamber were designed, constructed and operated to burn oil shale. The constructed combustion chamber was operated satisfactorily for several hours of operation. The experiments were conducted at steady state conditions using different values of air fuel ratios. High combustion efficiencies were achieved at various operating condition. The combustion efficiency was noticed to increase with the increase of air to fuel ratio for each test. Carbon monoxide concentration in flue gas was found to decrease with the increase in air fuel ratio. This was associated with the decrease in oxygen gas and an increase in carbon dioxide. During experimental work chromel-alumel thermocouples were used to measure the temperature distribution within the flame. Exhaust gases were analyzed using (motor scan gas analyzer 8070). Concentrations of CO, CO2 and O2 in the flue gas were measured under various operating conditions. Carbon residue after burning was collected and analyzed.
