Load-Building Possibilities of Industrial Heating

The author gives a brief survey of the more recent achievements in industrial electric heating, and shows the increasing tendency of industries to adopt electric heating, particularly for high grade products. Specific installation for such processes as steel treating, copper and brass annealing, vitreous enamelling, glass annealing, baking japans, cores, bread, etc., on a large scale, are described and illustrated. It is shown that the quality of product has been improved by the use of electric heating with little if any increase in cost, and in many cases, at a lower ``over all´´ cost. The desirability of heating load for the central station is emphasized, due to its high power factor and load factor.
