In this classic work of engineering, Robert Wilson lays out the principles of designing and constructing boiler and factory chimneys that are both safe and efficient. Using practical examples and detailed diagrams, Wilson shows how to calculate the size, height, and strength of a chimney for a given site, taking into account factors such as wind, temperature, and materials. Whether you are an engineer, an architect, or a builder, this book is an essential reference for understanding the science of chimney construction.
