Moreover, the system of powdered coal conveying with primary air is the most important tache, whether the distribution of primary air is even or not directly relates to whether the distribution of powdered coal is even or not in all firing implement and nozzles, sequentially directly relates to whether it is hard to take fire, whether the fire is stable, whether there is coking and how about the heat efficiency of the boiler, hi addition, if there is jamming and deflagrate in the system of powdered coal conveying with primary air, severe safety accident can be resulted
良好的煤粉配風是建立合理的爐內空氣動力工況和穩定燃燒的必要條件。而其中一次
熱風送粉系統又是最重要的一個環節,一次風配風是否均勻直接關繫到煤粉在各燃燒器和各噴嘴中的分佈是否均勻,從而直接關繫到著火是否困難、火焰是否穩定、局部是否結
焦以及鍋爐的
熱效率高低。若一次風送粉系統發生堵塞和煤粉爆燃則可能引發嚴重的安全事故。
I was sure st. john rivers - pure - lived, conscientious, zealous as he was - had not yet found that peace of god which passeth all understanding ; he had no more found it, i thought, than had i with my concealed and racking regrets for my broken idol and lost elysium - regrets to which i have latterly avoided referring, but which possessed me and tyrannised over me ruthlessly
