Preparation of Industrial Solid Waste into Boiler Fuel with a Single Horizontal Shredder

In the spring of 1980, a horizontal shredder, complete with an infeed and outfeed system as represented in Fig. 1, was placed in service at the Kodak Park solid waste disposal facility in Rochester, New York. This shredder has become the primary shredder for preparing solid waste for incineration in a suspension-fiied boiler. The ver­ tical shredder, which has been in service since 1970, was then relegated to service as an opera­ tional backup. This new shredding system represents the cul­ mination of Kodak Park's efforts over the past 10 years to resolve its solid waste preparation prob­ lems. Before discussing the details of this shred­ der installation, a brief review of the operating problems and modifications which have evolved from this experience will be presented.
