| 摘 要： | 文章以江西大唐抚州电厂2×1 000 MW工程为例，对超超临界锅炉设置邻炉蒸汽加热系统进行了研究。针对本工程的热态清洗温度，推荐采用一级邻炉蒸汽加热系统，即在除氧器中利用邻炉蒸汽直接将给水加热到锅炉热态清洗温度，实现本台炉不点火的情况下完成锅炉本体的热态清洗。该系统可节约锅炉启动过程中的燃料量，具有较大的节能效果及经济效益。设置邻炉蒸汽加热系统后，两台机组20年折现综合收益为1 404万元。

| Abstract: | In this paper adjacent boiler heating system of Jiangxi Datang Fuzhou 2×1 000 MW ultra supercritical unit has been studied. In consideration of the hot washing temperature of the project, one stage adjacent boiler heating system was adopted. Boiler feedwater was directly heated to hot washing temperature in deaerator by adjacent boiler auxiliary steam. In the whole process of hot washing of boiler, the boiler was not ignitied. It can save a mount of fuel in the boiler startup process, with great energy savings and economic benefits. After adopting one stage adjacent boiler heating system, two units' discount comprehensive income of 20 years can reach up to 14.04 million yuan. |
