煤气明火加热炉与钢管马弗炉的应用对比

对煤气明火加热炉和钢管马弗炉的结构、控制系统、操作方式、工艺参数进行对比:煤气明火加热炉属于直接加热,比钢管马弗炉加热速度快,热效率高,节省燃料20%~30%;明火加热炉的炉内气氛可调,压力可控,后续生产的铅耗和酸耗比钢管马弗炉分别降低11.9%和4.7%;明火加热炉的烧嘴侧向安装,维护方便,而钢管马弗炉烧嘴顺向安装,易出现炉温波动,且钢管容易烧损,运行成本增加;明火加热炉的Dv值比钢管马弗炉的Dv值高4~5 mm.m/min。试验表明,钢管马弗炉与明火加热炉处理的钢丝力学性能差别不大。

Application comparison of gas burning opening furnace with steel tube muffle

To compare the furnace structure, control system, operation mode and parameters of gas burning opening furnace and steel tube muffle. The conclusion is： gas burning opening furnace belongs to direct heating, has faster heating speed and higher thermal efficiency than steel tube muffle, save fuel 20% to 30% ; inner atmosphere of opening furnace is adjustable, the pressure is controllable, compared with steel tube muffle the lead and acid wastage cut down on 11.9% and 4.7% respectively; the burners of opening furnace are fixed at side, so maintenance is more convenience than steel tube muffle whose burners are fixed along tube, the furnace temperature of steel tube muffle fluctuates easily and steel tube muffle cost increases due to the tube is easy to burn damage; the Dv value increases 4 -5 mm.m/min with opening furnace; experiment shows that the mechanical properties change small with the two kind of furnace.
