负荷变化对鼓风式炉床扩散燃烧器射流状况的影响

INFLUENCE OF VARIATION OF LOAD ON EFFLUX STATUS OF AIR-BLAST SPREADINGFLAME BURNER IN BED

根据ＩＯ．Ｂ．伊万诺夫的射流理论，以燃气射流的穿透深度为参数表征燃气与空气的混合状况，从而表征燃烧器的工作状态，从理论上得出了对鼓风式炉床扩散燃烧器燃气射流穿透深度与过剩空气系数的关系，分析表明，对于鼓风式炉床扩散燃烧器，为保证燃烧工况良好，最好能配备燃气空气比例调节器。

According to the efflux theory of IO.B.иваНов, the penetrating depth of gas efflux is taken as the parameter to indicate the mixed status of gas and air, thus, indicate the working condition of burner. And we can get the relation between the gas efflux depth and surplus air coefficient of airblast spreadingflame burner in bed theoretically from it. The further analyses show that it would be better to equip with the proportional regulator of gas and air for airblast spreadingflame burner in bed to guarantee a good combustion status.
