7月7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”继续在山城重庆盛大召开。第二天的会议依旧干货满满,精彩不断!

本次会议以“节能降本 绿能助力 提质增效”为主题,四川省水泥协会理事长,西南水泥有限公司党委书记、总裁薄克刚;国家发改委宏观经济研究院研究员崔成;中国水泥网理事长单位理事长,亚洲水泥(中国)控股公司执行长张振崑;新疆建材行业协会会长吕志坚;重庆市水泥协会秘书长熊科;中国水泥网理事长单位,东方希望重庆水泥有限公司总经理侯健;成都中建材光电材料有限公司总经理、博士潘锦功;中国水泥网理事长单位理事长,惠州市光大水泥企业有限公司总经理陈灿辉;广东汇江氢能产业工程技术研究有限公司总经理张大康;河南省建筑材料工业协会秘书长丁振宇;青海省建材工业协会常务副会长于秀英;中国水泥网创始人、董事长邵俊等水泥企业负责人、行业协会领导、技术专家、设备商代表参会,共同探讨新局势下水泥行业节能降本新路径。

南京凯盛国际工程有限公司技术中心副主任钟根带来《水泥工业烧成系统节能降碳技术及应用(以预热器五改六为例)》主题报告。他表示,水泥企业节能降碳的技术路线主要有降低煤耗、降低电耗、废气治理、低碳排放等。从徐州龙山5000t/d预热器五改六项目来看,根据改造前后生产指标计算,从节煤角度,本项目年节约标准煤21000吨(年产熟料150万吨计),年减排CO2量为57750吨。

对于那些预热器不适合五改六的生产线,钟根建议从以下几个方式解决:一是五改六局部旋风筒的减重:如无耐火材料或超薄耐材的C1筒等;二是烧成系统(五级预热器)及分解炉本体的深度优化:个性化的方案,一厂一策;三是“五级+”(或5.5级),局部高固气比;四是替代燃料的应用。

国家能源太阳能发电研发(实验)中心高级工程师张双庆以《新能源发电在水泥行业中的应用技术分析》为主题进行精彩演讲。他表示,水泥行业碳排放的主要来源包括三个方面:原料带入(工艺排放)、燃料带入(燃烧排放)和电力消耗(间接排放)。水泥行业产生的二氧化碳约占全球排放的7%,我国水泥行业CO2排放约占12-14%,排放量全国第三。

张双庆详细分享了分布式光伏发电、储能技术应用相关内容,他指出,分布式光伏是目前水泥行业首选新能源投资领域,分布式光伏电站CCER开发。随着储能成本的不断降低,以及储能在削峰填谷、节能降碳等方面的作用凸显,可作为将来重点投资领域。对于持有废弃矿坑的水泥企业,可在条件具备的情况下,因地制宜投资建设分散式风电场。要推进新能源重卡、生物质发电、余热利用在水泥行业中的应用。

中国水泥网高级顾问、水泥粉磨实战专家邹伟斌以《水泥粉磨系统节能降耗技术改造措施分析》为主题进行精彩演讲。他详细介绍了水泥联合(半终)粉磨系统、辊压机水泥半终粉磨工艺系统、选粉机系统、陶瓷研磨体等相关内容并强调,水泥企业应重视粉磨技术研究。

邹伟斌指出,水泥工业发展将围绕以“洁净生产、节能减排”为中心,开展各项技术创新工作,包括高效节能粉磨设备与新工艺的研发与应用,降低粉磨系统电耗任重而道远。“系统节能是硬道理”:对传统粉磨理论的继承、创新与发展;根据实际工艺状况,对粉磨系统的不断总结及持续改进与提高、加快技术进步。

中国水泥网高级顾问高玉宗带来《生物质替代+协同处置》为主题的精彩报告。他表示,生物质燃料泛指由生物质组成或萃取的固体、液体或气体燃料,是可再生能源开发利用的重要方向,可以替代燃煤,减排CO2

高玉宗指出,替代燃料技术方案的难点在于:采取何种模式收集和储存生物质。重点在于:采用何种炉型焚烧生物质要根据长期主要处置的种类而定。技术路线:生物质进厂--临时储存--粉碎--密闭输送--计量入焚烧炉--焚烧—高温烟气气入分解炉--残渣排出或入炉--助燃可以采用三次风或自然风--可以离线或在线布置。关键点在于:影响成本和效益的关键因素是运距和水分,消防和稳定的供应能力同样重要。

中国水泥网高级顾问贾华平带来《水泥窑富氧需要辩证思维》主题报告。他表示,富氧煅烧优势诸多,一是富氧煅烧能提高燃料煤的活性,进而提高煤的燃烧速度、提高其燃尽率;二是富氧煅烧能降低煤的燃点,提高燃烧的集中度和火焰强度,进而减少燃烧的边际损失,增加燃烧热量的利用率;三是富氧煅烧能提高火焰绝对温度,进而提高燃烧温度、减少传热过程的㶲损失;四是富氧煅烧能提高火焰黑度,进而提高辐射强度和强化辐射传热,在水泥回转窑内辐射是主要的传热方式。

贾华平强调,要用辩证思维打破已有经验的束缚,对于水泥窑的富氧煅烧来讲,富氧不是关键,只是要求可靠的设备运行、稳定的气体含氧量。关键是煅烧,“煅烧”是水泥生产方的专业和职责,缺经验应该自己去摸索、去总结。

重庆通用工业(集团)有限责任公司满超进行《高效离心透平装备在水泥行业的应用介绍》精彩分享。他表示,以水泥、钢铁生产为例,大型风机系统约占其总生产用电的20%,但我国传统大型风机系统,很长一段时期内运行效率仅为40%~60%,在运行效率、能效等指标方面与国外存在显著差距,而重通集团的技术可以解决上述问题。

三一重工股份有限公司泵路事业部营销公司副总贾小虎带来《以创新赋能行业高质量发展》报告。他表示,随着“双碳”政策的发布,“绿电+绿氢”将成为我国实现双碳目标的重要组成部分,而绿氢行业正处于大爆发期。三一集团依托自身优势,全面布局绿电制氢、储氢、运氢、加氢等环节,从而促进零碳产业园及零碳城市的发展。

浙江中锦材水泥技术有限公司市场总监郑益琪进行《一种新的窑外分解系统发明专利及其应用实践》主题报告。他详细介绍了预热器、分解炉、窑头燃烧器技改的相关内容,譬如通过混煤燃烧系统(MCCS)(专利核心技术),有焰燃烧变无焰燃烧,提高了热效率,降低了窑内通风,消除了结皮,降低了热耗。

郑州宇通矿用装备有限公司、宇通矿卡西南大区总经理宋宗党带来《新能源矿用车助力绿色智慧矿山建设》报告。他表示,目前矿山运输、挖装等工序配备的设备动力主要消耗柴油,一条150万吨的水泥生产线在矿山开采过程中,矿山年消耗柴油约为400吨,碳排放量达到1280吨,其中燃油矿用车碳排放量超过60%。而新能源矿用车是解决矿山开采碳排放最有效的手段。

湖南赢科储能科技有限公司市场总监张典进行《电化学储能在水泥行业的应用》精彩演讲。她指出,水泥行业的碳排放占据全球总碳排放的7%,中国水泥行业的碳排放占据整个工业领域的20%。水泥行业节能减排是国家“双碳”战略实施的主战场。而建设储能电站是水泥企业应对双碳双减目标、建设绿色工厂、低碳工厂的有效途径。

一天半的会议为行业提供了一个开放交流、探讨、学习的平台,现场高朋满座,气氛热烈。7月7日下午,与会嘉宾们还将参观东方希望重庆水泥预热器“5级改6级”节能示范线、蒸汽拖动风机节能项目等。

未来,中国水泥网也将继续与全行业一起,让技术在交流中传播,让思想在沟通中碰撞,推动水泥行业绿色发展进程不断加快!
