Design Development of Portable (Mini) Multi-function Incinerator for Dry Medical Waste Handling.

Abstract

Medical waste contains biohazard, such as dry medical waste from the Centre of Public Health Services (PUSKESMAS) should be burning out, especially in the pandemic of covid 19. One of the possible solution is burning the waste by using incinerator. Basic concept of incinerator is controlled high temperature combustion, thus it should be perfect condition to burnt out the hazardous waste. Heat energy that exposed while incinerator operated should having high potency to be used for other purposes such as water heater and carbonization process. This research aims to develop an incinerator which can be used not only as high temperature burner (as incinerator’s main function), but also for water heater system and carbonization process, in the same time. The incinerator designed as mini portable incinerator since it will be used in a center of public health services (PUSKESMAS). Both of hot water and charcoal produced while incinerator operation can be used for sanitation purposes in the PUSKESMAS itself. Combustion process temperatures, smoke quality, safety factor, and energy utilities are the parameters which were determined as incinerator performance. Some design improvement has been done to the original design by Pradipta and Agustina [1] in order to improve the incinerator performance. The latest design performance is showing that combustion temperature successfully increased up to 980 °C for combustion rate of 9 kg waste/hour. Utilization of heat energy produced by combustion process inside the chamber has been successfully produce 2-2,5 kg of good quality coconut shell charcoal and hot water of 83 °C at 6 lt/minute flow rate.
