Pyrolysis and incineration in polymer waste management system
Abstract
Waste and associated risks are becoming an increasingly noticeable problem in environmental protection in our time. The management of especially industrial waste is a difficult and at the same time a significant problem. Incineration is the basic process of thermal utilization. The combustion process is not neutral for the environment, and is associated with the emission of dust, sulfur and nitrogen compounds as well as dioxins and furans. Therefore, combustion installations must be equipped with a number of devices for cleaning the exhaust gases. The most primary process of obtaining useful energy from biomass, i.e. combustion, is characterized by specific dynamics. Regardless of the technique, it is affected by physical and chemical processes. The condition of economic and technical correctness of co-firing is maintaining the optimal share of biomass in the fuel mixture and its appropriate quality. Effective co-firing of the prepared mixture can be carried out in existing grate, fluid and dust boilers. Pyrolysis is a stage in both the combustion and gasification process. In this process, as a result of the thermal decomposition of the structure of the organic fuel, we obtain carbonizate as well as tar and gas products.
