制浆造纸行业的可持续性和能源效率提升通过工程设计提升能源效率

Sustainability and Energy Efficiency in the Pulp and Paper Industry:About Engineering the Energy Efficiency

自《中华纸业》2015年第7期刊登了第一篇由贝利公司相关专家编写的“制浆造纸行业的可持续性和能源效率提升”第一篇文章之后，贝利公司便在《中华纸业》杂志上开启了“贝利细说可持续”话题，从第一篇中的如何衡量、比较和评估造纸生产设施的可持续性，如何定义能源效率，工厂所有者该如何将投资聚焦在准确的目标对象上，实现未来发展的可持续性，并满足高效率和高性能的运行要求，到第二篇的讨论欧洲和中国在法规方面的根本区别，以探索造纸行业在环保法规方面面临的挑战。此文是“贝利细说可持续”话题的第三篇，着重讨论制浆造纸行业一些典型的能源效率提升领域，并有对近年来能源消耗总体发展情况的讨论。

The devil is in the details; i.e. there are no easy single tricks to improve the overall energy efficiency of an operating plant. However, a structured approach to improve the efficiency needs to be employed. In practice this means focusing on a single piece of equipment and evaluating short payback items. Virtually each mill has multiple non-identified improvement objects that, by correct measures, can have payback times shorter than one year. This paper will discuss and highlight some typical improvement areas in the pulp and paper industry, supported by discussion related to general energy consumption development over recent decades.
