Abstract:

This manual contains a procedure for the design of stacks on U.S. Naval ships based upon the experience already gained by the Navy as well as commercial ship stack design practices. The techniques described in detail include design guidance for the height and shape of exhaust gas stacks, prediction of plume trajectories, estimation of downwind plume gas temperatures, and model testing techniques. The manual is divided into two parts. The first part contains a step-by-step procedure, with examples, for auxiliary vessels with conventional stacks and combatant vessels with low profile stacks. Design tools are included in the form of tables, graphs, computer programs, etc. The second part of the manual contains the basic rationale, historical and experimental foundation for the design practices as well as a section describing model testing techniques. In addition, problems unique to Naval ships, such as air operations and temperature limitations of topside electronics gear, are discussed.
