"高温水采暖与蒸汽采暖"目前这两种方式,如没特殊需要,都不直接供与采暖系统,也就是说,纯蒸汽采暖系统由于能耗高(主要热损大),不安全,在工业与民用建筑里已经逐步淘汰,近几年的气(暖)改水(暖)的工作基本上把上世纪留下来的老蒸汽采暖系统全部改造完毕,但有些地方(有春秋管道系统)还有可能保留部分,有些城市中的城区蒸汽管网由于出现过爆炸等不安全问题加之蒸汽的输送与环境温差比较大,热损失也大.因此都在推广的热水采暖管网系统!热水采暖管网的好处就是热损失小,运行管理安全,节能(循环水),热水系统节能还在于不少工业余热都能置换成热水输送到采暖系统,使得工业废水余热得到了充分利用!
在给你说一下高温热水采暖:高温热水采暖,上世纪七,八十年代,出现了不少燃煤燃油高温热水锅炉,由于热效率大多都在75%,浪费较大,不节能,加之环境保护的要求,逐渐的也没了市场,逐渐的被热电联产(电厂余热)的城市集中供暖代替,城市热网(主干网)刚发展时,许多地方都是建立的都是蒸汽管道,许多系统还都不设冷凝水回流回收系统,一至于浪费较大,加上蒸汽管网的技术要求高,热媒温度高因此其保温措施要求也高,运行后一旦维护不到位,蒸汽管网系统的安全和节能隐患就显露出来了(蒸汽外网系统都这样,户内采暖当然更不是最好的选择了),还有闲置时的内部保养也没热水系统好做,所以近几年的不少地方也都把城市的主干网都改成了热水系统!
由于城市的主干网是为用户提供热源的,所以大都采用的是高温热水输送(115-130/75-85),但是用户采暖系统还是低温水采暖,按以前的低温水采暖是95/75.现在由于技术的改进和户网的不间断供暖的要求,才有的都是机组出口不高于85度的热水,如果一个供暖站较小的系统,实际出水温度55-65度就很能满足用户系统的要求,加之地板采暖方式不适宜高温的要求,所以现在采暖换热站的温度不能高于65-85度!
综合上述:高温水采暖(115-130)只适宜于城市主干网的热源输送,到用户系统必须进行水-水交换成低温水(65-85),采用低温大流量不间断供暖,优点是,节能,环保,安全,供暖平稳,效果好,工程造价低(比较蒸汽和高温水系统而言)!
蒸汽采暖系统:热损大,不安全,不节能,系统不易保养!安全技术要求较高,工程造价响应也高,好处就是温度高,没有特殊要求一般不采用这种方式,比如:以前医院的产房手术室,要提前或延期送暖气,必须单独设一路蒸汽为其供暖,这就是所谓的春秋管!现在的这点要求已经被空调系统代替,所以也就没有设置这种管路的了!因此,纯蒸汽采暖系统可以说已经不适应发展了,已经退出了!
大半夜的给你写这么多,如有这方面的东西需要交流,请联系我,哈哈,希望对你有帮助!
1.跟蒸汽比热水要安全得多.
2.节能，成本低。
水的热容适中，降温相对较慢。而蒸汽升温快，降温也快，热损耗比较大，对管道的要求也相对较高。
3.噪音小。
