North American Combustion

Hi!Can anybody help me with this regulations about the calculation of thermal losses from a static + postcombustion cilindrical chambers of an incinerator of hazardous wastes (mother liquor, off-gas and solvents)? The temperatures of the products of combustion (internal temperature) and of the external ambient are, respectively, 880°C and 20°C for the static chamber. For the postcombustion chamber I have the following T : 850°C and 20°C. Which others parameters I need?Can anybody help me with books, manuals, equations..... about this calculations?

Thank you very much!

Andrea

This is not a trivial problem. At these temperatures there is probably a substantial amount of radiation exchange between the combustion products and the chamber walls. This is on top of convective heat transfer.

The amount of radiation exchange is dependent on gas emissivity & tranmissivity, chamber wall temperature, particulate loading (if any) and even the shape of the chamber.

Convection will depend on gas velocities, gas properties, wall friction and wall temperature.

Any decent heat transfer book will have enough tools so you can take a stab at calculating the heat loss. But I wouldn't bet the house on your answer.

Hi Lance!Thank you very much for your point of view about my problem.I've this book on heat transfer: KERN- Process heat tranfer. What you think about this book?Please let me know.Bye!

Don't know anything about Kern, it might be fine. But when I see the term "process" I think this book is more about heat exchangers than radiation heat transfer.

How about good ol' Heat Transfer by Holman?
