前言钢铁工业是国民经济中能源消耗最大的部门,而轧钢加热炉又是钢铁工业能源消耗的大户。全国加热炉的能耗约占钢铁工业总能耗的30％。然而加热炉却又是各种工业炉中热效率最低的一种,其热量损失占总热量的60％左右。因此许多国家都把降低单位燃耗作为发展加热炉的重要出发点,节约能源已成为现代加热炉的发展方向。
Preface The steel industry is the sector that consumes the largest amount of energy in the national economy, and the rolling furnace is another big energy consumer in the steel industry. National heating furnace energy consumption accounts for about 30% of the total energy consumption of the steel industry. However, the furnace is the lowest thermal efficiency of a variety of industrial furnaces, the heat loss accounts for about 60% of the total heat. Therefore, many countries regard reducing unit burnup as an important starting point for the development of reheating furnaces. Energy conservation has become the development direction of modern reheating furnaces.
