This book presents the results of a pioneering study of heat transmission through boiler tubes, which was conducted by the Bureau of Mines. The study involved the development of a novel method for measuring the temperatures of both surfaces of a boiler tube while the boiler was in operation, enabling the authors to determine the temperature drop along the path of heat travel from the hot gases into the boiler water. The authors found that the temperature drop from the hot gases to the gas-side surface of the tube is high, whereas that through the metal of the tube itself and from the metal to the boiler water is low. This means that the metal of the boiler tube is nearly at the same temperature as the boiler water, indicating that as long as the boiler is kept free from scale, oil, or other deposit the tubes cannot be overheated, even if the boiler is operated far beyond its rated capacity. The book also includes discussions of radiation, convection, and conduction as they apply to heat transmission in boilers, as well as an overview of previous research on furnace wall heat losses and heat transfer in boilers. The authors' findings have had a significant impact on the design and operation of steam boilers, contributing to increased efficiency and safety in steam power plants.

Excerpt from Heat Transmission Through Boiler Tubes
Radiation is that mode of heat propagation by which heat passes from one body to another without the aid of any material agency. In the case of a furnace and the heating plate of a boiler, the heat from the hot fuel bed and furnace walls flows by radiation through the space filled with gases, directly to the boiler plate, without heat ing the gases appreciably.
The quantity of heat that is transmitted from the hot parts of the furnace to the boiler plate is closely proportional to the difference between the fourth powers of the absolute temperatures of the hot parts of the furnace and the boiler plate.
