Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法,在不考慮燃燒的冷態情況下,研究了熱風
爐燃燒室內的氣流分佈規律.在此基礎上,比較了2種不同設計方案的氣流流動特徵,尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和
煤氣的流動和混合的影響.結果表明,阻流板的設計對加強空氣和
煤氣的混合有著極為重要的作用,同時也增加了空氣管道的阻力損失,在同樣的工況條件下需要提高管道系統的總壓力
