“垃圾不够烧”背后的产业变局

"我们采用了我国具有自主知识产权的炉排炉技术,热效率比10年前提升了40%。"马科军指着中控室大 屏幕上的焚烧线介绍,垃圾在近1000摄氏度的高温下充分燃烧,据检测报告,二噁英排放浓度仅为欧盟 标准的1/10。 近年来,我国垃圾焚烧产业技术自主化程度不断提高。2004年,重庆三峰环境集团股份有限公司历经4 年技术攻关,成功研制出首套国产化垃圾焚烧炉,并应用于重庆同兴垃圾焚烧发电厂。2005年,重庆同 兴垃圾焚烧发电厂建成投产,打破核心设备全部依赖进口的局面。 "真正的突破是在智能化领域。"马科军边演示智能燃烧系统边介绍,"我们自主研发的自动化燃烧控制 系统,能根据垃圾成分自动调节炉排速度和风量,使热效率稳定在85%以上。"这套系统让西咸北控每 年可多发电1500万千瓦时,相当于节省标煤1220吨。 此外,西咸北控还建成了自动化控制系统,可通过炉内实时数据预判燃烧状态。三维可视化界面实时显 示着4条焚烧线的2000多个监测点,当热值传感器检测到垃圾含水量骤增时,系统便自动启动应急模 式,提前加大干燥段热风量,将燃烧温度波动控制在2摄氏度内。 "现在,我们发愁的是垃圾不够烧!"6月23日,陕西西咸新区北控环保科技 ...
