1 000 MW二次再热机组建设无油电厂的技术经济性分析

锅炉点火方案的选择对燃煤机组的运行费用及点火稳燃的可靠性至关重要，以1 000 MW二次再热机组为例从技术角度对可行的节能点火方案(微油点火、等离子点火、天然气点火)进行了对比，并以具体工程为例进行了经济性计算，1 000 MW二次再热机组建设无油电厂综合技术经济性最优。由于1 000 MW二次再热机组建设无油电厂尚无实际运行经验，也对该配置方案的风险及对策进行了进一步分析，以供工程实施参考。综合性技术经济性评价方法也适用于其他容量等级工程的点火系统设计方案优选。

Technoeconomic Analysis about Oil-free Ignition Technology of 1 000 MW Double-reheat Coal-fired Power Plant

The ignition technology is extremely important for lower operating cost and ignition reliability of coal-fired power plant. The article discussed ignition technology (oil-less ignition, plasma ignition, natural gas Ignition) about 1 000 MW double-reheat coal-fired power plant from technological aspect, and developed an economic evaluation based on the actual unit. The result shows that for 1 000 MW double-reheat power plant, oil-free ignition technology has lower operating cost. Because of no operation experience, the risks and countermeasures for 1 000 MW double-reheat unit to take oil-free ignition are processed furthermore to offer reference for execution. The integrated technoeconomic analysis method can also be applied for ignition technology selection about other capacity units with its broad applicability.
