Fabric selection is a critical component in the operation of a dust collection system venting a waste to energy boiler. This paper will discuss the factors to be evaluated when selecting the proper fabric to use in filtration systems venting waste and refuse derived fuel fired boilers. Consideration will be given to the type of scrubbing equipment, the type of cleaning system, the design parameters of the unit, and the gas stream chemistry. Operating experience from existing filtration systems will also be presented. Special emphasis will be made on equipment design, particulate capture and filter service life. A look at new developments in fabric filtration, including fabric blends, micro-denier filtration, and the use of pleated filter technology, will complete this overview.
