摘　　要：锅炉房和煤仓间是火电厂的主要建筑。对神华国华宁东发电厂二期2×660 MW高效超超临界机组扩建工程煤仓间布置的技术方案进行分析,通过优化论证,决定采用2台锅炉与煤仓间联合布置的技术创新方案。该方案煤仓间布置在2台炉之间,即2台炉合用1个煤仓间,给煤、制粉系统对称布置;优点为设备布置紧凑,工艺管道短捷,建设体积小,施工周期短,工程造价低,检修维护方便。采用煤仓间联合布置技术的宁东发电厂2台660 MW机组,分别于2017年8月31日和2017年12月26日投产运营,截至目前已运行1年多,整体情况良好,运行平稳,各项数据指标均优于设计要求。实践应用表明,该项工程技术经济性明显,具有较好的应用前景。Boiler room and coal warehouse are both the main buildings of the thermal power plant. This paper analyzes the technical scheme of coal silo layout in the 2×660 MW high-efficiency ultra-supercritical unit expansion Phase II Project of Shenhua Guohua Ningdong Power Plant. Through the procedures of optimization and verification, the technical innovation scheme of 2 boilers and coal silo layout is finally determined. In this scheme, coal silos are arranged between two furnaces, that is, two furnaces share one coal silo. Coal and pulverizing systems are arranged symmetrically. This innovated design has the advantages of compact equipment layout, short process pipeline, low construction volume, short construction period, low project cost and minimum effort in maintenance. The two 660 MW units of Ningdong Power Plant, which adopted the design of joint arrangement between coal warehouses, were placed into service on August 31, 2017 and December 26, 2017 respectively. So far they have been running well and smoothly for more than one year with all performance indices exceeding the design requirements. The application practice shows that the technology is apparently economical with promising application prospect.
