Modification design of incinerator multifunction continue type
Abstract
Incinerator is an equipment to incinerate trashes with high temperature control to ensure that the combustion process was done completely. The previous design of batch type incinerator which has been designed by Pradipta (2011) has some disadvantages, such as heat transfer system, loading and unloading system, air supply system and utilization of heat energy. So, those design should be modified to improve its performance. The performance parameters of incinerator are temperature of combustion, the rate of combustion, quality of exhaust gases, safety factor, and utilization of heat energy. Modified incinerator has eight sections (combustion chamber, chimney, air inlet, hopper, boundary plate, ash chamber, charcoal chamber, and water heater pipe). The performance test shows that the highest combustion temperature is 689.6 ⁰C, with combustion rate 5.78 kg / hour. The incinerator is safe for operator and the exhaust gasses has good quality. Utilization of thermal energy could increasing water temperature up to 32 ⁰C. Air inlet position was not in the proper place, so combustion temperature could not reach as high as expected. Therefore it need improvement.
