摘要(Abstract):
从理论层面对影响风机电流的因素进行分析,针对可控因素从实际运行方式角度提出1 000MW机组降低风机电流的有效运行措施,对低氮燃烧器超超临界锅炉有一定的指导意义,也对其它型式燃烧器的炉型具有参考价值。
The elements that affect fan current are analyzed theoretically. In the light of controllable factors,effective operation measures for reducing fan power consumption rate of 1 000 MW units are proposed in terms of practical operation mode, which can not only be applied to ultra-supercritical boilers with low NOX burners but also to boilers with other types of burners.
