Book excerpt: Heat Exchange in Shaft Furnaces focuses on the theory of heat exchanges occurring in the shaft furnace process. It covers the development and research done by experts in the field of physics, chemistry, metallurgy, and engineering. The book contains the exposition of the aspects of the theory of heat exchange in shaft furnaces and draws examples from the field of blast furnace operation. Researches by scientists; laboratory experiments; and practical results derived by workers on blast furnaces in the theory are skillfully synthesized and expounded. Topics on exchange in packed beds; heat transfer in the blast furnace; and the state of the theory of heat transfer in a blast furnace are discussed. Metallurgist, plant researchers, physicists, chemists, and engineers engaged in the design of blast furnaces will find the book invaluable.
