本文将对华能正宁电厂可研方案坝址和初步设计方案坝址选择进行经济技术比较,可研方案坝址选在燕家村灰场中上游,一期灰场堆高至1070m标高,二期扩建继续堆高至1075m后,需要重新修建坝址,利用下游山谷继续堆灰,新建坝址位于原坝址下游。灰渣由汽车运输,灰场运灰道路出口设置在厂区东南侧,一期燕家村灰场新建运灰道路长约1.5km,二期扩建需新建道路约0.5Km。初步设计方案可研坝址选在燕家村灰场中下游,沟口较窄位置,一期灰场堆高至1026m标高可满足贮存一期灰场3年贮灰要求,二期扩建不需要重新修建坝址,利用一期灰场原有坝址。灰渣由汽车运输,本期灰场运灰道路出口设置在厂区东南侧,本期燕家村灰场新建运灰道路长约2km。经比较认为初步设计方案更经济,更环保。

换流站广泛采用交流滤波器进行谐波滤除和无功补偿.交流滤波器内C1电容器不平衡电流过大成为了一个严重影响换流站投运调试进度和交流滤波器不平衡保护动作后设备故障处理时间的重要因素.传统的调整方法只能靠经验和趋势来判断,调整电容器单元的工作量大.本文结合±500kV永仁换流站调试实际,提出一种行之有效的不平衡电容调整方案.建议在C1电容器两端加一序列电压,低压端接地,将不平衡CT两端引流线接入,利用电流
绘制标准工作曲线,是火电厂化学监督在使用比色分析法分析相关物质前的首要工作,它的准确与否关系到物质浓度测量的准确性.为此,本文从比色分析法的原理和实际操作规范出发,分析得到三点影响工作曲线绘制准确性的影响因素:朗伯比尔定律影响因素、操作细节与仪器使用规范,建议在操作过程中必须严格保证单色光入射,要保证化学反应所使用的药品为优级纯级别;另外,吸取药品前首先观察试剂瓶底部是否有沉淀,如有沉淀,则需避免
