Comparative analysis of MSW thermal utilization technologies for environment friendly WtE plant

A comparison of the technologies of thermal utilization of solid chemical waste was carried out, the advantages and disadvantages of the thermal utilization technologies of WtE thermal power plants used in worldwide were given. A method of comparison and selection of the preferred technology of thermal utilization, depending on the specific conditions of the placement of TPPs at MSW, is proposed. Thermal utilization can be classified into three categories (combustion, gasification and pyrolysis), the difference between them lies in the amount of excessive air present in combustion chamber. The gasification technology that can be often in use in WtE can be divided into two main types – slugging gasification and plasma gasification.
