摘要
某热电厂2#锅炉系东方锅炉(集团)股份有限公司生产的DG1069/17.4-Ⅱ1型电站锅炉,针对其在运行过程中,沿炉宽方向床温分布呈中间高两边低的趋势,最大偏差超过100℃的问题,对该厂2#炉开展了运行数据分析、床温偏差的风帽改造方案设计、改造效果分析等一系列工作。改造前后的运行数据对比显示:绝大部分工况下床温偏差都得到明显改善;同时改造后床层阻力增加相对较小,改造效果良好。文中研究可为相关电厂同类锅炉的优化改造、以及国产大型循环流化床锅炉的节能降耗提供极有价值的试验数据、成功改造经验与技术借鉴。
The second boiler is the equipment of Dongfang Boiler Company in a thermal power plant,which model is DG1069 /17. 4-Ⅱ1. The bed temperature distribution is higher in the middle than both sides during the boiler operation. To solve the problem,carried out the operating data analysis,the improvement program of nozzles and the effectiveness analysis of the program,etc. The data comparison shows that the bed temperature difference has been significantly improved in most conditions,while there is a small bed resistance increasing after the transformation. This paper provides valuable test data for the energy saving of similar CFB boilers.
