各个导流槽101所在的环形区域的内径与燃气通道102的直径的比例大于或等于1.5:1，导流槽101的大小与燃气通道102的气流量有关，气流量越大需要的通道也就越大，即所需的导流槽101也就越大，这样才能保证足够的混合气体流经导流槽101，因此，本申请将各个导流槽101所在的环形区域的内径与燃气通道102的直径的比例大于或等于1.5:1，以保证流经导流槽101气体量，以利于混合均匀，并保证具有较好的引射效果。

结合图2以及图5，引导切面110可和导流槽101对应设置，引导切面110设置在对应的导流槽101的上部，使燃气可通过该引导切面110进入到导流槽101内，以进一步减少燃气向外环火盖300的混气腔流向的阻力，更有助于燃气的引射。

结合图8-图11，分气件100设置有燃气通道102、进气通道118、扰动通道119以及气道103，其中，气道103的一端通过进气通道118和燃气通道102的出气端连通，扰动通道119具有相通的第一端以及第二端，扰动通道119的第一端连通在燃气通道102的中部，扰动通道119的第二端和气道103连通，扰动通道119的出气方向和进气通道118的出气方向具有扰动夹角，内环火盖200以及外环火盖300均设置在分气件100上，内环火盖200的混气腔和燃气通道102的出气端连通，外环火盖300的混气腔和气道103的另一端连通，扰动通道119即为上述匀气部。

结合图8-图11，由于分气件100还设置有扰动通道119，扰动通道119的第一端连通在燃气通道102的中部，扰动通道119的第二端和气道103连通，扰动通道119的出气方向和进气通道118的出气方向具有扰动夹角，因此，进入到燃气通道102的燃气在从燃气通道102的出气端排出之前，可部分流入至扰动通道119内，从而可减少向内环火盖200的混气腔的燃气流量，以降低内环火盖200的负荷，平衡内环火盖200和外环火盖300的燃气的进气量，同时，从燃气通道102的第二端排出的燃气和从进气通道118排出的燃气会在进气腔内相遇时形成旋流区以增加扰动，有助于燃气与一次空气的混合，使燃烧更充分，以减少CO排放量，具有很好的实用性。
图12为图8中的分气件的结构示意图。结合图12，分气件100包括内环进气部104，该内环进气部104整体可呈筒状，内环进气部104沿轴向设置有贯通所述燃气通道102，即燃烧器在使用时沿竖向设置，燃气通道102的底端为进气端，该进气端和炉头的引射管连接，通过炉头的引射管可向燃气通道102输送混有一次空气的燃气，并从燃气通道102的顶端(即出气端)排出，即形成了单喷嘴上进风燃烧器。

需要说明的是，本申请实施例中的扰动通道119也可形成一个空腔结构，即扰动通道119使内环进气部104分为上部和下部，二者之间的空隙为扰动通道119，此种情况下，内环进气部104的上部和下部可通过间隔设置的连接柱连接。
结合图8以及图11，内环火盖200的混气腔间隙设置在内环进气部104的上方，内环火盖200的混气腔和内环进气部104的之间的间隙限制为上述进气通道118。
