Fabric Filtration of Flue Gases from an Active Incinerator: Studies on Design Optimization and Operational Analysis

The paper describes the use of bag filters in the dry gas cleaning system of an incinerator as a safe and economical method for treatment of the flue gas from an incinerator burning low-level radioactive solid combustibles. Various types of fabrics were evaluated to find the filtration characteristics during the entire cycle of operation. Data on pilot plant studies carried out to optimize a suitable design of fabric filter for flue gas cleaning is included. Cost comparison of different fabrics based on the life of the fabric and the cost of fabric filtration per unit of solid wastes treated has been given. The physical, chemical and radiochemical nature of the aerosols encountered in various parts of the incinerator system are described. (author)
