The Research On The Slagging Problems Of No.1 Boiler Of Inner Mongolia Fengtai Electric Power Generation Co.ltd

This thesis establishes the main factor of heating surface slagging of No. 1 boiler, that it is due to irrational layout of furnace heating surface, improper angle of burner which lead to flames attaching to furnace walls. Such deduction is built on the basis of necessity of analyzing the heating surface slagging, the type of coal, the design of the furnace and burner, the operational condition and other factors effecting slagging of boiler. The research is mingled with practical operations of No. 1 boiler in inner Mongolia Fengtai Electric Power Generation Co, LTD. The reform scheme of No. 1 boiler in Fengtai Company is confirmed on the basis of cold/hot tests, theoretical discussions and calculations. In the process of field retrofit, it is indicated in the operation of the improved furnace that without the change of furnace structure, the transform of the burner angle has shrunk the tangential diameter and prevented flames burning on furnace walls, and the burning state of furnace has been bettered, simultaneously, lowering the slagging wi in furnace, thus laying sol id foundation for the safe and economic operation of generating units.WuYanRong(power plant Thermal power engineering) Directed by prof. liuTong...
