Abstract
LINKING theory with practice is always beset with difficulties, and in no branch of engineering science are these greater than in heat transfer. In a modern boiler, for example, heat is conveyed from the fuel to the water-tubes by direct radiation from the firebed, and from incandescent soot particles, carbon dioxide and water vapour in the furnace gases, as well as by reflected radiation from surrounding refractories, and by convection from the gases. The rational approach to such a complex set of conditions is undoubtedly first to determine the fundamental laws of radiation, convection, etc., and then to apply them in building up a picture of what is happening in the actual furnace. Ways of improvement can then be foretold, and new designs worked out.
