Abstract:

There exists, currently, no comprehensive procedures for design of coal-fueled power plant ductwork in the publicly available literature. This dissertation presents such a procedure. An overview of the ductwork design environment, including major components of the air and flue gas flow paths, design loads and temperatures, corrosion considerations, and physical configurations, is given. Design criteria for materials, corrosion inhibition, minimum plate thicknesses, temperature effects, allowable stresses and deflections, and vibrations are proposed. A detailed design procedure based on the allowable stress design philosophy is presented, and computer programs implementing the design procedure are provided. an alternate design procedure based on the Load and Resistance Factor Design approach is also discussed. The allowable stress design procedure is applied to a horizontal section of rectangular ductwork and the results are compared to a previous design accomplished by hand calculations. The proposed design procedure provides savings in both ductwork material and fabrication labor, and consumes significantly less design time than the by-hand design approach.
