Emissions investigation for a novel medical waste incinerator

---

Abstract.
Medical waste constitutes one of the waste streams that should be dealt with special priority due to its
potential negative impact on public health and on the environment. Incineration is a process that is widely
used for the treatment of medical waste. However, self-supporting combustion of medical waste cannot
avoid releasing many hazardous pollutants into our environment. The most favored solutions are firing
additional fuels of high calorific value and direct purification by air pollution control devices (APCD). This process entails not only large first time investment but also an increase in the operation cost. A novel
incinerator is proposed for better utilization of energy of the incineration process. Its originality is essentially due to combining a feeder, a rotary grate, a cylindrical gasifier and a “coaxial” secondary combustion chamber into a unique unit. The structure of the incinerator as well as the principle of the incineration process is presented in this paper. A full-scale trial of the novel incinerator with APCD was carried out fromMarch toMay 2008 to investigate howthe distinct configuration influenced the incineration process. Data on PM, CO, NOX, O2 were recorded by a continuous emission monitoring system during the study
period. Heavy metals and PCCD/Fs were also sampled and measured. Measuring results were compared
with the China and U.S. EPA guidelines. The concentrations of contaminants were below their respective
limits in emission control standards. Results from testing the novel medical waste incinerator confirmed
that this technology has a good suitability for neutralization of medical wastes and purification of flue
gases.
