解釋
標準煤樣-
We select crm without coal as reference ; select semi - dynamic atmosphere to operate machine ; use the method fixing the temperature of hearth and that of sample holders when the analysis begins, which ensures the consistency of heating samples ; adopt the dta curve of " at - t " to analyzing crm heat, which decreases possible influences from the fluctuation of heating velocity ; draw conclusions that crm proportion and granularity influence the analysis little, but not crm moisture and coal species ; advise that there be a warm - up to the crm with much moisture before analysis and a modification to the crm with variable species of coal ; then obtain the feasible operation conditions and operation curve ( together with the curve function )
選用白生料作標樣;選用準動態測定氣氛;採用恆定爐膛溫度( 650 )和固定支持器初始溫度( 60 )的方法,確保了樣品受熱過程的一致性;採用「 t ? ? t (時間) 」 dta曲線分析生料熱,減少了升溫速率的微弱變化對測定結果的可能影響;得出生料配比和細度對差熱儀測定結果影響小、生料水分和煤品種影響大的結論,並提出對大水分生料測定前要進行預熱處理、對不同品種煤的測定結果要進行修正的建議。最終,得到了差熱儀適宜的工況條件和工作曲線(及方程) 。
