One objective in a part of the research and development of infectious waste incinerator in Thailand is to determine the optimum operating condition of the incinerator such as the operating temperature of primary combustion chamber. By the fact that combustion process in primary combustion chamber is principally controlled by the thermal destruction behavior of waste, consequently, thermogravimetry (TGA) tests have been conducted on the thermal decomposition of the major components of infectious waste which mostly found in Thailand's hospital, i.e., cotton, rubber glove and PE syringe. The results of these tests show that the decomposition of waste material significantly depend on the thermal destruction temperature. The tests are also done with the simulated infectious waste, with the composition similar to the real waste. The results show significant features between these materials. Energy engaged at the early stages of decomposed materials can be used as an accumulated energy to destruct the other portion of material at higher temperature. The TGA results also use to compare with the evolution of primary chamber temperature and carbonmonoxide gas emitted during the combustion of infectious waste in a prototype controlled-air incinerator. The understanding of combustion behavior from this study could be used for determining the optimum operating condition of the prototype incinerator.Thermogravimetry, infectious Waste, Controlled-Air incinerator, Combustion Behavior.
