摘要
为了深入研究引风机电动和汽动两种驱动方式对机组经济性的影响,针对某工程2×660 MW超超临界机组的引风机不同驱动方式进行计算和比较。通过对电动驱动引风机、凝汽式小汽机驱动引风机和背压式小汽机驱动引风机3种方案的技术经济比较,指出在发电煤耗和供电煤耗方面,定速电动机驱动的动调引风机方案要比其他2个方案都低,因此推荐采用此方案。
In order to study the impact of two driving modes including electric and steam on the economy of unit, we calculated and compared different modes for 2× 660 MW ultra-supercritical units in a project. According to the technical and economic comparisons of three kinds driving modes for the IDF including electric, condensing steam turbine and backpressure turbine,the coal consumption of the first driving mode is lowest, therefore the electric driving mode for IDF is recommended.
