降碳效果显著!生物质替代燃料在水泥行业应用仍存巨大空间!

2021-12-16 14:09:51

由此看来,我国水泥行业在生物质替代燃料的推广应用上仍存在巨大空间。但可喜的是,像海螺水泥这样的龙头企业已经率先布局,为提高替代燃料的使用率做出有益尝试。

日前,为促进新疆水泥行业绿色低碳发展,推动新疆水泥行业碳达峰、碳中和步伐,新疆建材行业协会组织召开了水泥窑利用棉花秸秆替代燃料技术交流会。

与会代表认为,通过利用新型干法水泥窑的技术优势,建设生物质替代燃料项目,坚持科技创新,积极破解秸秆处理难题,满足水泥熟料的大规模化生产,节约资源,降低生产成本,实现秸秆减量化、无害化处置,使令新疆农民头疼的棉花秸秆变废为宝,实现循环利用,同时优化能源结构,达到节能减排的目的,不仅可缓解水泥工业对煤炭的依赖性,同时可将秸秆等生物质“废物”燃料化工艺形成技术标准,可带动区域内的生物质“废物”资源化产业发展。有专家表示,可以先选择一家水泥企业进行改造,先行先试,形成可复制、可推广的有效模式,力争让更多农民和水泥企业享受到技术进步带来的实惠,实现良好的生态效益、经济效益及社会效益。

实际上,生物质替代燃料在水泥行业的应用早已不陌生。

2020年10月,铜陵枞阳海螺水泥有限公司生物质替代燃料项目一期工程建成投产,该项目是国内水泥行业首套生物质替代燃料系统,项目通过利用新型干法水泥窑的技术优势,积极破解秸秆处理难题,项目一期正常运行后预计每年可节省原煤约4.9万吨,同时可处理掉秸秆等生物质“废物”约15万吨/年,且正常运行后还将实现生物质替代燃料替代率超过40%。

枞阳海螺生物质替代燃料项目

铜陵枞阳海螺水泥有限公司生物质替代燃料项目每年利用秸秆等生物质15万吨/年,实现年节约标准煤7.3万吨,缓解水泥工业对煤炭的依赖性,减少水泥窑煤的用量及二氧化硫、氮氧化物、温室气体的排放,是推进水泥生产工业“低碳、环保、减排”的有效途径,对水泥行业节能减排和废物资源化利用具有重要意义,具有良好的社会效益、经济效益和环境效益。

不仅仅是海螺水泥,华润(集团)有限公司党委书记、董事长王祥明也曾公开表示,华润水泥将全面推行绿色矿山建设,推广替代燃料、碳捕集等技术应用,加快实现碳达峰、碳中和目标。

当前,工业领域节能减碳形势日趋严峻,水泥企业需要加强节能降耗并寻找替代能源,这既是当前能源形势下的迫切需求,也是降低碳排放、压减煤炭用量的必然途径,而生物质替代燃料就是水泥企业实现节能降耗的重要方式之一。

所谓生物质是指利用大气、水、土地等通过光合作用而产生的各种有机体,即一切有生命的可生长的有机物质。它包括植物、动物和微生物,不同于石油、煤炭、核能等传统燃料,这些新兴的燃料是可再生燃料。

以秸秆作为替代燃料为例,有数据显示,以5000t/d水泥熟料生产线按窑尾喷煤占70%计算,窑尾分解炉全部用秸秆代替燃煤,每年可政策性减少CO2排放37.3万吨。同时,秸秆热值3000-4000kcal/kg,非常适合分解炉替代燃煤,可以100%替代分解炉用煤,降碳效果均十分显著。

而纵观国内现状,生物质能的发展却始终未能得到足够的重视。当前我国年产秸秆量超过10亿吨,但作为生物质能的主要原材料之一,其能源化利用率仅为3%左右。

由此看来,我国水泥行业在生物质替代燃料的推广应用上仍存在巨大空间。但可喜的是,像海螺水泥这样的龙头企业已经率先布局,为提高替代燃料的使用率做出有益尝试。未来,随着水泥行业坚定不移地走绿色低碳发展之路的理念深入贯彻,业内也必将会涌现出更多使用替代燃料的优秀范例。

In general, if the alternative fuel is mainly domestic waste or general industrial combustible waste, when the substitution ratio is high, it may bring more alkali content to the clinker, thus causing the 28-day strength of the clinker to decrease. Because the calorific value, combustion rate and feeding rate of alternative fuels fluctuate greatly, the output and quality of clinker will also increase.

The cement industry has been clearly included in the carbon emissions trading market in 2024. Cement enterprises need to comprehensively and accurately understand the relevant regulations and guidelines. According to the actual situation of the enterprises themselves, they should seek advantages and avoid disadvantages, turn inward, practice hard, continuously reduce their carbon emissions per ton of clinker, reduce the production cost of clinker, and win in the current industry trend. So that their enterprises can survive and develop better.

2024-09-25 09:05:05

Although the road of carbon emission reduction in the cement industry is full of challenges, through continuous technological innovation and industry practice such as "steel slag phase-separated clinker", we have reason to believe that the cement industry can surpass the "face-saving project", realize the real green transformation, explore a sustainable road of cement concrete development, and leave a cleaner and sustainable earth for future generations.

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.
