李坤明:四大路径提升水泥行业能效水平

2023-07-06 17:56:06

水泥在生产中消耗大量的能源和资源,如何提高能效水平和降低排放一直都是行业实现高质量发展的一个重要任务,同时也是政策的重要导向点。

7月6日,由中国水泥网主办的“2023中国水泥节能与新能源发展大会”在山城重庆盛大召开。

中国水泥网·水泥大数据研究院水泥分析师李坤明以《水泥行业能效现状与未来:道阻且长,未来可期》为主题进行精彩演讲。他表示,水泥是建材板块中最大的能耗行业,2022年熟料产量大概在14.3亿吨,煤耗量超1.5亿吨标煤。水泥在生产中消耗大量的能源和资源,如何提高能效水平和降低排放一直都是行业实现高质量发展的一个重要任务,同时也是政策的重要导向点。

未来水泥行业能效水平提升路径有哪些?李坤明认为,一是广泛应用节能技术装备,使用高效篦冷机、窑头燃烧器等节能装备。二是实施节能技术装备升级改造,对预热器、风机、电机变频、窑头燃烧器等进行技术改造,节约电能、提高煤粉燃烧速度。三是建设能源管控中心,对各生产工序中所有用能设备进行监测及控制,精细化分析能源使用。四是大力推进协同处置固体废物,水泥窑协同处置生活垃圾、市政污泥、危废等,提高燃料替代率。

李坤明强调,替代燃料存在巨大的发展空间,也是水泥行业实现节能提效减碳的重要途径,提高替代燃料使用率是我国水泥行业提高能效水平的重要方式。不过尽管前景广大,其存在的问题也较多,譬如废物来源种类比较单一、生活垃圾含水量比较高、替代燃料热值不稳定等。

In view of the problems of declining profits of cement enterprises hindering green transformation and narrowing the space for energy saving and carbon reduction, Ye Jiayuan proposed that cement enterprises should not forget to innovate no matter how difficult it is. Innovation should not only be limited to low-carbon areas, but also open up ideas and plan digital upgrading and intelligent transformation as early as possible according to their own conditions. In the implementation of digital and intelligent transformation, it should be linked with low-carbon as far as possible. If digital intelligence leaves the foothold of low carbon, digital intelligence is likely to be hollow, and it is likely to become a castle in the air, which is not useful, but a burden for enterprises.

Cement demand in 2024 is expected to continue the trend of the previous two years and continue to decrease. The downstream of cement is mainly divided into three parts: infrastructure, real estate and new rural construction. It is expected that the demand for infrastructure and rural market will remain stable. The key is whether the growth rate of real estate investment can stabilize and rebound, thus supporting the demand for cement.
