| Medical solid waste come from the refuse in the process of medical diagnose and therapy. There are bacteria, virus, vermin and other harmful substance in the wastes. If not being disposed timely, they will pollute circumstance severely. Because of not being paid enough attention, medical wastes have been a cause of unhealthy of people.At present, the research of municipal solid waste has been carried out widely. But the disposals of medical solid wastes do not start up. The paper gets the content of ash, moisture, volatilization, carbon etc by the industry analysis of medical wastes. Then discuss the combustion characteristic. The research shows that medical solid wastes have high content of volatiles and high heat value which is far higher than that of municipal solid wastes. The character of high content of volatiles indicates that the wastes can be ignited easily and can combust steadily. A system of medical solid waste CFBC incinerator has been manufactured and it is based the characteristic of medical solid waste. First , the wind flow simulation experiment was carried out and the relationship between layer resistance and primary air was analyzed from the experiment of CFBC Medical solid waste layer resistance was investigated, and the influence of layer ply & diameter of Medical solid waste on layer resistance and minimum fluidize air flow flux was analyzed too. Second, the combustion experiment is carried on. During the experiment , the influence of combustion parameter on combustion and air pollution was been analyzed. From the analysis , the conclusion can be drown that in the proper condition , the air pollution of medical solid waste CFBC incinerator can be reduced and controlled to the level that can be accepted.The paper lays a foundation for further research of medical wastes clean combustion technology. It has notable environmental benefit and will boost popularization of medical wastes integrating control technology.
