电伴热在垃圾焚烧发电厂的运用

信息来源:摘录 浏览次数:415 发布时间:2018-01-17

    垃圾焚烧发电是当前比较新型的环保型垃圾处理方式之一。主要发电原理是将生活垃圾送入焚烧炉中焚烧,过程中产生蒸汽,用蒸汽来发电,在目前看来这是一个很不错的处理生活垃圾的方法。因为采用焚烧方式处理生活垃圾,所以此类发电厂有着严格的净化程序,使垃圾焚烧之后无害化。不过最主要的是这类垃圾焚烧发电厂其主要职能是焚烧垃圾,发电只是随赠附带。这种垃圾焚烧技术于上世纪90年代末传入我国,目前已有蔓延发展之趋势,通常情况下这类垃圾焚烧发电厂分为两类,一类为正规垃圾焚烧发电厂,采用技术完全引进自欧洲,同时由各国优惠的贷款来建施工与运营。通常这类垃圾焚烧发电厂有严格且先进的烟气过滤回收系统,投资巨大。日处理垃圾从几百吨到几千吨不等,一般这类垃圾焚烧发电厂投资额都在几亿人民币之上,这类垃圾焚烧发电厂由于技术先进并对环境保护意识很看重,所以都会使用电伴热系统,且投资资金很大。比如上海浦东垃圾焚烧发电厂以及上海江桥垃圾焚烧发电厂,这两家发电厂都是采用欧洲先进技术建成的,投资金额都超过了5亿人民币。另一类则是地方上自行设计投产的垃圾焚烧类项目,这类垃圾焚烧发电厂由于资金不足,往往就很少使用电伴热系统。

 

垃圾焚烧发电厂专用电伴热带


    自限温电伴热带在垃圾焚烧发电厂主要作用于垃圾焚烧后的飞灰凝结在设备表面。通常情况下,很多管道和阀门都需要电伴热带,当然对于灰斗、灰仓和反应器可能只需要下部伴热。
    垃圾焚烧发电厂为非防爆区,对温度控制要求并不高,维持温度与暴露温度,一般有两种产品满足要求,耐高温的自限温电伴热带和MI加热电缆,在我们中国一开始最初的工艺为MI加热电缆并且现在国内的垃圾焚烧发电厂设计师们都会借鉴国外设计理念,使用MI加热电缆的可能性相当高。
