范文题目：加强运行节能降耗管理
摘    要
 2011年是实现“十二五”发展目标的起步之年，贯彻落实党中央、国务院关于节能工作的方针政策，促进全面协调可持续发展，进一步加强发电企业节能管理工作，推动节约能源，实施清洁生产，提高能源利用效率，保护和改善环境，降耗增效。电力生产工作主要任务是：加强设备管理，提高设备健康水平，确保不发生重大设备事故，努力减少非计划停运，保持等效可用系数领先，全面开展优秀节约环保型燃煤发电厂创建和能耗指标创优活动，总体能耗指标要保持领先优势，主力机型能耗指标要达到领先水平。目前，部分发电企业燃煤灰份大、热值低，明显超出设计能力，辅机设备处于超负荷运行状态，更难以达到新节能标准的要求。因此要及时调整负荷和煤质变化下的机组运行方式，千方百计查找原因，做好节能精细化管理，节约每度电、每克煤，坚决遏制发电企业和机组能耗指标反弹势头。
 发电厂节能降耗管理是全过程控制管理，从设计阶段就要强调采用高效成熟的技术，辅机设备选型可靠高效和低故障率；在营运阶段要强调持续改进和设备技术更新，节电节能精细管理。本文在查阅大量中外科技文献资料基础上，从提高汽轮机及锅炉效率、降低厂用电率、无泄漏治理、机组参数“压红线”运行等五个关键环节，就如何降低煤耗、降低厂用电控制策略进行了简单介绍，对影响能耗的因素进行了分析。重点从运行管理的角度分析了如何提高运行管理技能，克服负荷率低、煤质差对机组经济性的影响，介绍各种节能降耗措施，优化锅炉燃烧调整及低负荷下的优化运行工作。

 Thesis title: strengthening the management of running energy saving and consumption reducing
ABSTRACT
 2011 is the "Twelve-Five" start of the development goals of the year and the implementation of the Party Central Committee and State Council guidelines and policies on energy-saving work to promote comprehensive, coordinated and sustainable development, further strengthening the energy efficiency of power generation enterprise management, promote energy conservation, cleaner production, energy efficiency, protect and improve the environment, reducing consumption and increasing efficiency. Power production main tasks are: strengthening equipment management, improve the health status of the device, to ensure that no serious incidents of equipment in an effort to reduce unplanned outage and maintain equivalent availability factor leading, carrying good saving and environment-friendly coal-fired power plants to create activities for optimization and energy consumption indicators, indicators to stay ahead of overall energy consumption, energy consumption indexes of main models to achieve the advanced level. At present, some power plant coal ash, low calorific value, significantly ahead of design capability, in a State of overload operation of auxiliary equipment, more difficult to meet the requirements of new fuel economy standards. So you want to adjust loads and coal quality change unit operation under way, and do everything possible to find reasons, energy-saving fine management, savings per unit, per gram of coal and resolutely curb energy consumption indexes rebound momentum of power generation enterprises and units. Power plant management is whole course control of energy saving and management, from design to emphasize the use of high performance proven technology, auxiliary equipment selection for reliable high efficiency and low failure rate; technical update stage to emphasize continual improvement of operations and equipment, power-saving energy-saving fine management. Access to a large number of domestic and foreign scientific literature data on the basis of this article, from raising of steam turbine and boiler efficiency, lower power consumption rate, no leakage parameters of governance, unit "red line" running of the five key links on how to reduce coal consumption, reducing service power control strategy for a simple introduction, provides an analysis of factors affecting energy consumption. Focus analysis from a management perspective on how to improve the operation and management skills, overcome low loading rates, poor coal quality effect on unit economic, describes various energy saving measures, optimizing boiler combustion under low load and adjustment of the optimization work.
