煤成份中各主要項目彼此間有一定的關連性存在,且煤質對鍋爐運轉
之影響甚鉅,以粉煤機為例,機粉煤能量為粉煤細度,煤之水份含量和研磨
性之函數,於使用時宜慎選所燃用之煤質以避免粉煤機之研磨能量不足,造
成發電機組被迫降載運轉.因此,本研究的主要目的是利用文獻提出之方法
及製造廠商所提供之經驗公式,撰寫評估程式,用以評估媒質之特性及其對
鍋爐機組運轉性能,效率和污染排放之影響.並且由計算結果得到控制參數
變化之初步瞭解,再進行現場實驗和調校,以得最佳操作條件.

The major components of coal has a great influence on
boiler operation.Take mill for example , the capability of mill
depends on the fineness ofpulverized coal , the moisture of coal
, and grinding . Therefore , while coalis burning , we should
carefully choose coal property to avoid mill being deficient in
capability and thus results in the generator de-load . Thus ,
thepurpose of this experimented is to use the ways which the
documents have offered and the experimented formulas provided by
the manufactures to work out the evaluation formula and , hence
, use such a formula to evaluate the characteristicsof coal
property and its influences on boiler operation and emission .
