基础植筋技术在脱硝改造中的应用

Application of technology of planting steel bar on basis in denitration system reformation

火力发电厂在进行脱硝设备安装或改造时,由于已建老旧机组没有预留脱硝设备安装位置,原有基础不能满足强度要求。以山西漳山发电有限责任公司一期2×300 MW机组脱硝改造工程为研究对象,对基础植筋加固方案、技术要求及施工工艺进行了总结和分析,保证了设备安全和改造工作顺利进行。

In the old units of thermal power plants,the installation site was not reserved for flue gas denitration equipment. The original basis can not satisfy the strength requirement of the denitration equipment. Taking the denitration reformation project of the 2 × 300 MW unit of Shanxi Zhangshan Power Generation Company Limited Phase I as research object,the basis planting steel bar and strengthening scheme,the technical requirements and the construction technology were summarized and analyzed.The equipment safety was ensured,and the reformation was accomplished successfully.
