Abstract

Several types of fabric filters are used to remove fly ash from the products of combustion of large coal-fired power plants. This article compares two types of cylindrical bags: inside collectors and outside, or pulse, collectors. A synopsis of the evolution of the outside collector precedes a discussion of the merits and shortcomings of both types of collectors. Various claims made by adherents of outside collectors are then discussed. Finally, the costs of replacing bags in the two types of collectors are compared.
