Thirty-two incinerators current legally operated for the transmissive hospital wastes. During the past, I visited those process site, according an appointment by Environmental Protection Agency, to interview the employe as well as to give the training courses and workshops. During the imitation of a prototype of the incinerators as the references for the operators of incinerators, we must collect the following information: (1) information regarding to the incinerator self, such as capacity; (2) possible composition of the hospital wastes; (3) the composition of the exhaust gases; (4) the components in the combustion fuel; (5) characteristics of combustion process inside of incinerator. In this study, we chose an incinerator in Hospital A as a model to establish an incinerator operation standard. The degrading coefficiencies for hospital waste will be served to understand the down-grading ratio, the variation of the sizes of products, the curve of temperature inside of incinerator and the concentrations of HCl and Sox upon the amount of excess air. This information will be the bases to establish the process for evaluation the amount of toxic exhaust gas and low the combustion fuel and reduce the toxic exhaust gases.
