一、概述我国现有各种工业炉窑和工业锅炉近50万台，是国家的一个耗能大户。由于技术落后，设备陈旧，操作水平低，存在着热效率低、耗能高的问题，与国外同类炉窑相比，热效率低10－20个百分点。上海第一钢铁（集团）公司钢板厂现有加热炉三台，炉子的有效面积为4.64*32.42—1
First, an overview China’s existing various industrial furnaces and industrial boilers nearly 500,000 units, is a major energy consumer. Due to backward technology, outdated equipment and low operation level, there is a problem of low thermal efficiency and high energy consumption. Compared with similar foreign kilns, the thermal efficiency is 10-20% lower. Shanghai First Iron & Steel (Group) Co., Ltd. has three reheating furnaces at present. The effective area of the furnace is 4.64 * 32.42-1
