The document discusses the design and types of chimneys. It begins with an introduction on the function and applications of chimneys. It then discusses the different types of chimneys based on material, lining material, and number of flues. The document outlines important design aspects like sizing, structural parameters, and loads. Finally, it presents several case studies with salient features of different chimney projects.
