国电投遵义公司自备火电厂以“一分钱”提质增效专项工作为抓手，通过技术突破、管理精算与全员共识的深度融合，实现了发电量与效益的双重跃升。截至11月初，电厂累计完成发电量6596.5万千瓦时，同比提升1532万千瓦时，供电优化降本达505.5万元，更创下7至10月连续四个月刷新单月发电量纪录的亮眼成绩，这背后是企业打破思维定式的技术革新实践。过去电厂秉持“低压省煤”的固有认知，党员攻关团队联合技术专家大胆突破，在确保锅炉额定压力13.7兆帕、汽机额定压力12.7兆帕的前提下，将主蒸汽压力从10.0-11.0兆帕提升至12.2-13.2兆帕稳定运行，不仅让机组每小时发电量增加600度，还将排汽温度从450摄氏度降至430摄氏度，成功解决了一段抽汽管道长期超温的难题。针对1号机组抽汽管道超温导致的能源浪费，电厂经与原设计单位充分论证，将管道温度稳定控制在430摄氏度，顺利投运1号高压加热器，达成“一石三鸟”的成效——每小时提升发电量约800度，锅炉给水温度提高20摄氏度，燃烧效率显著提升，这套被技术员张月繁称为能量“回收站”的系统，让原本散失的热能转化为实实在在的电能。

在管理层面，电厂构建“机组、外供汽、锅炉、回水”四点平衡模型，制定精细到吨的调控策略，当负荷低于每小时215吨时投入“高加”系统，高于225吨时退出，在保障生产用汽的同时实现发电效率动态优化。此外，通过协同调度、稳定回水、关闭备用炉冷渣机冷却水等措施提高除盐水温度，进一步减少蒸汽消耗;针对设备启停中的电量损失，电厂打破“先停后等”的旧模式，实现停机检修与蒸发工序同步，锅炉启动正常后汽轮机立即暖机、随时准备并网，每次启停可抢回约12小时有效发电时间，多发电量约6万千瓦时。

更重要的是，电厂通过“我为扭亏脱困建言献策”等活动激发全员创造力，累计征集建议201条，发放奖励4.096万元，月均采纳率大幅提升，含煤废水二次利用、自主清理油冷器等“微创新”年节约费用超330万元。从主操监盘时紧盯关键参数、严控偏差，到一线员工践行“每发一度电，都算精细账”的共识，“效能文化”已渗透到生产全链条。遵义电厂的实践印证了“技术突破+管理精算+文化渗透”的成功逻辑，既在设备额定参数框架内探索出最优运行区间，又通过数据驱动的动态平衡机制实现“供汽-发电”效益最大化，更为自备电厂在“双碳”背景下应对政策压力、巩固能源转型“压舱石”地位提供了可复制的实践样本。
