當焦炭推上攔焦車進入熄焦器后,立即關閉罐蓋,同時啟動真空泵、冷凍機、高壓循環水泵,這時,燃燒著的焦炭就會因真空泵把熄焦器內抽成負壓,由於缺氧,使焦炭熄滅,雖然煤炭在瞬間被熄滅,但由於焦炭生成過程中所產生的大量的熱量還存在,這時,冷凍機和夾層中的循環水的工作就會把焦炭中的熱量帶走,使之在短時間內將溫度降到60以下,在這種狀態下把焦炭從熄焦器內推出入庫,焦炭就不會復燃。Continuous carbon fiber reinforced silicon carbide ceramic matrix composites ( cysic ) are considered as the most promising thermal structural candidate materials for aerospace, energy and nuclear technologies etc. as a key technology for improving high - temperature structural applications of the materials, oxidation protection with anti - oxidation coating system had being paid more and more attentions
