In this chapter the reader will be taken through the various methods of heat recovery steam generator (HRSG) construction. HRSG construction varies widely in levels of modularization and order of assembly of the components. We’ll explore what is important, considerations for specific jobsites, and design influences. Every part of the HRSG from the inlet duct to the stack including piping, supports, valves, platforms, and auxiliary systems such as burners, catalysts, and ammonia injection components will be covered.
