工厂蒸汽节能技术解析

日期： 2025-05-09 作者：晟德亿编辑

一、蒸汽系统有哪些组成部分？

1.蒸汽发生系统；

2.蒸汽输送系统；

3.蒸汽排水系统；

4.冷凝水回收系统；

5.冷凝水处理系统

二、蒸汽用户的常见问题:

不平衡的蒸汽系统；

没有利用二次蒸汽和余热；

严重泄漏和浪费；

冷凝水未回收；

关键阀门质量不合格；

设计选择的管理和维护存在很大问题。

三。蒸汽发生系统节能技术:目前蒸汽来源主要是自备锅炉或外部热电厂集中供热。

3.1如果是自备锅炉:

a、首先要选择能效更高的新一代节能锅炉，当然也要考虑是否符合环保要求(比如现在很多城市要求使用天然气锅炉，不允许使用燃煤锅炉，所以用户需要尽快将煤转化为气)；

b、尽量选择燃烧效率大于80%的锅炉；

c、锅炉压力应尽可能高，尽可能接近额定压力；

充分利用回收的余热，提高锅炉给水温度。事实证明，给水温度每升高6℃，锅炉所需燃料就会减少1%，这是非常可观的。大部分工厂只要做好正常的凝结水回收，锅炉回水温度就能达到80-85℃(当然，这意味着如果不漏汽，如果以疏水阀漏汽为代价提高回水温度，那损失就大了)。

E.锅炉污水必须回收:锅炉连续排污系统从锅炉底部排出的污水为高压热水，约占总蒸发量的5-10%，会产生大量闪蒸汽。建议使用排污扩容器进行回收和二次利用。

3.2如果是热电厂的蒸汽:

一般来说，发电厂产生的过热蒸汽温度高，压力大。大部分电厂一般先做降温减压，再给各企业供汽。而有些电厂只是降压，没有冷却，相当于给企业供应过热蒸汽。那么企业必须自己做降温系统，将过热蒸汽转化为饱和蒸汽，因为饱和蒸汽的热效率远大于过热蒸汽，更容易控制。
