介绍气候补偿器、烟气冷凝热回收装置、分时控制等燃气供热节能新技术。列举了两个应用燃气供热锅炉房节能系统的典型工程，对其投入节能系统前后进行了对比试验，并做了节能效益和经济效益分析。北京市的供热方式主要有四种：城市热网供热、区域锅炉房供热（含燃煤、燃气、燃油、电锅炉）、清洁能源分户自采暖（天然气壁挂炉、电采暖）和小火炉取暖。其中主要供暖方式是燃煤、热力和燃气供暖。为保证和改善大气环境质量，大力推广和使用了清洁能源，北京市正在将燃煤锅炉改为燃气锅炉。

另一种是轧制结束后，芯棒停止运动，荒管在线被装置将其从芯棒中脱出；我们将这种芯棒不动,荒管动的设备称为脱管机。脱管机既有两辊式的，也有三辊式的。脱管机的设置有两个重要的工艺目的：一是将荒管从芯棒上抽出，完成脱管目的。在轧制线上脱管，省去了脱棒机，缩短了工艺流程，提高了终轧温度；二是起校正（定径）作用，也就是说在每一支钢管生产中，该机也有延伸和定径作用。为生产薄壁管和中厚壁管，每架脱管机的孔型名义直径必须小于轧管机芯棒直径。镀锌层涂油涂油旨在钢板防锈。油品要在常温干爽的库存条件下一年内不变质；在涂装前处理的碱性涂油剂中可以容易清除掉。对于一些成品工件需要粘贴的部位是不允许有油存在的，而在工件上局部除油，在经济上、安全上和保存上都是不合理的，故一般选用无油板制作。不过无油镀锌板极其制作，要求其存放条件要苛刻些。即通风，无有害气体和灰尘，相对湿度不大于7％。油品，一般常用矿物油型防锈油（溶剂型），存放时，板材自重蜜叠，不易挥发。
