热风炉采用陶瓷燃烧器的优越性已由实践证明,但改装陶瓷燃烧器以后,若不对其附属设备进行相应改造,则会给操作工人带来不便.表现在: 其一,热风炉原用的套筒式燃烧器,是由一个双层套筒将煤气、空气输入燃烧室,因此只用一个燃烧阀就可切断(或打开)煤气、空气通道.采用陶瓷燃烧器以后,由于燃烧器结构的改变,需将煤气、空气通道分离.原来的燃烧器阀被两个切断阀代替.这样,在进行换炉操作时就多了一道换炉程序.即:原来的换炉程序中开(关)燃烧阀变为开(关)煤 The advantages of using ceramic burners in hot blast stoves have been proved by practice, but after the ceramic burners are retrofitted, it will bring inconvenience to the workers if they do not make corresponding alterations to their auxiliary equipment. In the sleeve burner, gas and air are fed into the combustion chamber by a double-layer sleeve, so that the gas and air passages can be cut off (or opened) by using only one combustion valve. Since the ceramic burner is used, Change, the need to gas, air channel separation. The original burner valve is replaced by two shut-off valve .In this way, the operation of the furnace when more on a furnace change process. That is: the original furnace program to open (off) The combustion valve turns on (off) the coal
