Industrial and Process Furnaces

Principles, Design and Operation

Industrial and Process Furnaces provides a comprehensive reference to all aspects of furnace operation and design, with coverage of key topics that plant and process engineers and operators need to understand, including the combustion process and its control, furnace fuels, efficiency, burner design and selection, aerodynamics, heat release profiles, furnace atmosphere, safety and emissions. * Helps to understand complex heat and mass transfer and combustion problems* Outlines the key elements of furnace theory for optimum design* Shows how to achieve best possible furnace operation* Practical, stepped approach breaks topics down to their constituent parts for clarity and easier solution * Practical examples further assist in the analysis of real-world problemsDeveloped by authors with experience of a wide range of industrial applications, this book is written for chemical and process engineers, mechanical, design and combustion engineers and students. It is ideal for both task-based problem solving and more detailed analysis work.

Audience
Professional engineers (chemical, mechanical, power, process, HVAC, environmental), designers, production staff who use heat and combustion as part of a processAdvanced students of Chemical, Mechanical and Powever Engineering (as a reference) dealing with energy conversion/thermal engineering.
