　　【化工仪器网政策标准】近年来，随着我国能源与环境问题面临越来越大的挑战，同时面对可持续发展与重视社会效益意识的加强，加之CO₂排放税、环境污染治理成本、政府优惠政策等经济影响因素的出现，以及中高温余热发电的成功应用，低温余热资源的发电潜力和经济性前景正得到越来越多的关注。低温余热双循环发电装置是大量余热充分利用的措施之一，该技术不仅可以回收各种形态的工业余热，极大地降低排放温度外，其产生的高品质电能还可以回用到系统中去，并降低高品位能源的消耗，达到节能减排等多重目的，利于能源可持续发展。

　　在能源危机和环境污染问题日益突出及节能减排的大环境下，这种经济、高效、节能、环保的低温余热利用方式具有广阔的需求空间和发展前景，为确保该方法顺利展开与运行，我国于2019年制订发布了《低温余热双循环发电装置》，对低温余热双循环发电装置进行统一、标准性的规定。但目前，针对低温余热双循环发电装置性能测试的标准仍是空白，这很容易使得装置的实际运行与设计出现较大的差异，甚至是装置不能正常运行的情况。

　　为严格约束和把关低温余热双循环发电装置的性能，降低装置实际运行的风险，中节能工业节能有限公司、天津大学等在中国电器工业协会的主管下，联合起草了《低温热源双循环余热回收利用装置性能测试方法》。目前，该标准已经编制完成，并正面向社会征求意见，意见征求时间截止至2020年6月20日。

　　阅读标准征求意见稿后可知，《低温热源双循环余热回收利用装置性能测试方法》规定了低温热源双循环余热回收利用装置性能测试方法，包括术语和定义、符号表、测试原理、测试准备、测试、测试数据整理和测试报告内容等。标准中指明需要的检测仪器包括有玻璃水银温度计、电阻温度计、热电偶和半导体温度计、弹簧管式压力表、压力传感器、U型管压差计和水银柱大气压力计、流量节流装置、液体计量容器和液体质量或体积流量计、功率表、电流表、电压表、功率因数表、频率表、互感器、耐电压检验装置等。

　　为确保实验顺利进行，标准还对测试方法的选择、测试结果偏差、测试时间、测试数据记录、被测装置的名义工况、被测装置名义工况下进行测试的性能要求等进行了详细的规定。

　　本标准是编制组经过广泛调查研究、认真总结各地实践经验、参照了大量国内外文献，并在广泛征求各方意见的基础编制的，相信标准在实施后能有利于该技术推广应用的标准化和产品化。为此，希望广大仪商积极建言献策，为标准的完善贡献一份力量。
