| Abstract | Five components of refuse were segregated and were used to study the effect of moisture content; temperature; carbon, hydrogen ratio and calorific value of heat on the thermal conversion efficiency of pyrolytic gas. Above l,500°F, the effect of moisture content on thermal conversion efficiency of gas was insignificant. The production of various pyrolytic products varies linearly with temperature. However, the rate of variation de pends upon the carbon-hydrogen ratio; moisture content. For most refuses, the optimal pyrolyzing temperature lies between 1,400 to l,700°F producing 14-26 percent char with calorific value of 6,000-13,000 Btu per pound; 30 62 percent liquid with calorific value of 6,000-23,000 Btu per pound and 12-39 percent gas with calorific value of 180-360 Btu per cubic feet! There is a positive relationship between carbon-hydrogen ratio and optimal pyrolyzing temperature of irrespective of the type of refuse used. Economic analysis indicate that even with slow rate of hoatingas indirect retort heating, the pyrolysis process is attractive specially with increasing fossil fuel costs. However the capital cost without gas upgrading equipment for pyrolysis is at least twice to that of incineration. Pyrolysis is a relatively cleaner process than incineration. |
