1000MW超超临界褐煤锅炉制粉系统选型优化

Study on Type-selection Optimization of Coal Pulverizing System for 1000MW Super-critical Lignite Boiler

通过对内蒙古大唐国际克什克腾发电厂2×1000 MW超超临界火电机组工程锅炉、制粉系统及磨煤机选型,配合开发具有我国自主知识产权的1 000 MW超超临界褐煤锅炉关键技术。开展1 000 MW超超临界褐煤锅炉制粉系统的优化研究,提出克什克腾电厂1 000 MW褐煤锅炉制粉系统选型参数,并提出了1 000 MW褐煤锅炉制粉系统参数选择范围,为1 000 MW等级超超临界褐煤锅炉研制提供技术支撑。

In order to assist developing the independent intellectual property key technology of 1 000 MW super-critical lignite boiler,this paper studies the type-selection optimization of pulverizing system used for 1 000 MW super-critical lignite boiler.The study is based on the type-selectionof boiler,coal pulverizing system,and coal mills from Datang Keshiketengqi 2×1 000 MW super-critical thermal power plant.The type-selection parameters of coal pulverizing system is proposed for 1 000 MW power plant,The parameter scope of the pulverizing system is also proposed,which could give technical support for the development of 1 000 MW-order super-critical lignite boiler.
