正文 第七十一章、超临界锅炉钢管不能自产？(第1页/共3页)
巴比奇睁大了眼睛：“秦，你能造这种钢材？”
“能啊，不过，不能用这批废钢，里面的镍铬含量太高，我需要用国内炼钢厂生产的粗钢，鞍钢的粗钢最合适。”秦川说道：“只要精炼一番就能做到。”
于红心站了起来：“好，我帮你去协调！”
“于叔，你先在这里测绘，测绘好了再去协调也不迟。”
“不，没有合适的钢材，这锅炉就无法测绘仿制出来，我还是先看到这种p92厚壁管造出来才会放心。”于红心说道：“你找辆车，送我去车站，我现在就去首都找领导。”
“首都？我派车直接送你过去，不用坐火车了，建设，你跑一趟！”
于红心风风火火地走了，下午四点钟到了首都相关部门，正好看到副厂长郭向阳也来了。
“郭厂长，您来做什么？”
“你来干啥？”
“我来……郭厂长，厂子有事？”
“是啊，你上次跑出来，就没见你回去，咱们厂最近又接了新的任务。”
郭向阳说道：“上级指示，为了进一步提升我们的火力发电机组的运行效率，我们需要预研超临界锅炉，这次我们就是来和法国阿尔斯通公司接触，看看能否从他们那里引进相关技术。”
“咱们终于要搞超临界锅炉了？”于红心顿时一喜。
在全世界，煤炭都是最低廉的能源，所以，目前国家发电主要用的也是煤炭，把水烧成蒸汽推动汽轮机，再带动发电机。
虽然技术原理从瓦特发明蒸汽机时候就开始用了，但是技术依旧在不断发展，热效率不断提升，从最初的百分之三，提升到现在的百分之四十以上！
国内的火力发电技术是老毛子援建的，在当年的156项工程中，冰城锅炉厂得到了中压锅炉技术，内部蒸汽压力低于6兆帕。
后来经过努力，逐渐提升到了高压和超高压的水平，最高压力能达到137兆帕，当然了，用的钢管也都是普通的厚壁管。
锅炉内部蒸汽压力越高，锅炉的效率也就越高。
在五十年代后期，美国就运行了31兆帕的锅炉，是全世界第一台超临界机组。
这是锅炉领域里的专业名词，解释起来也很简单，正常人都知道，水在100摄氏度下烧开就是水蒸气，水蒸气轻飘飘的，密度小。
而随着压力的增加，水烧开需要的温度也开始增加，水和水蒸气的密度差也开始减少。
