辽化公司制氢转化炉系从法国引进,该炉辐射室两侧壁上共有56个辐射墙式气体烧嘴。开工以来,烧嘴一直存在一些问题:受外界风向影响大,而引起炉温波动,使转化炉操作不稳;燃烧噪音大,达到126分贝,为此对侧壁烧嘴进行了简易有效的改造。改造的主要点是在烧嘴的尾部加一圆形消音筒,在消音简的内部装一个一次风门的调节机构,这样可使原来的一次风、二次风的入口流向发生改变。一次风首先进入消音筒内再向后转,进入一次风入口。二次风不是直接进入炉膛内,而是先平行于炉墙外壁再拐弯入炉。这样不仅消 Liaohua hydrogen conversion system from the company introduced from France, the furnace radiation chamber on both sides of the walls of a total of 56 radiant wall gas burner. Since the commencement of construction, there have been some problems with burners: large fluctuations in the furnace temperature and unstable operation of the reformer resulted in a large combustion noise of 126 decibels, which resulted in a simple and effective retrofitting of side burners . The main point of transformation is to add a circular muffler tube at the tail of the burner, and a primary damper adjustment mechanism is installed inside the muffler so as to change the flow direction of the primary primary air and the secondary air inlet. A wind first into the muffler cylinder and then turn back into a wind inlet. Secondary air is not directly into the furnace, but first parallel to the outer wall of the furnace and then turn into the furnace. This is not only canceled
