Various kinds of industrial furnaces in different sizes are often used in each industry. In Japan, the estimated number of industrial furnaces is about 39000. Energy saving development of industrial furnaces started with the first oil crisis on 1973. Since then various kinds of development and improvement have been performed. Examples of blast furnace plants and reheating furnaces for rolling mill are given on this paper. The development of the high temperature air combustion system of high performance furnaces is succeeded and getting spread in the market. JIFMA s activities for International standards for industrial furnaces ISO/TC244, new work item of method of measuring energy balance and calculating efficiency will contribute to the low carbon society. Key Words : Industrial furnace, Energy saving, High temperature air combustion, High performance industrial furnace, International standard, Oxy-combustion 1. はじめに 90 39,000 1,000 * Corresponding author.
