锻造炉是我厂锻工车间的主要设备,也是主要耗能设备。使用的燃料是重油。我们厂锻工车间共有7台锻造炉。由于炉型结构不合理,耐火材料蓄热量大,保温性能差,油咀型号落后,烟道阻塞,烟气从炉门排出,带走大量热量,前后炉门都敞开着,大量冷空气自炉门而入。过剩空气系数高达2=1.42～1.78。经热平衡测试,这几台锻造炉的热效率很低,仅达6％。所以,能源浪费严重,同时也严重地影响了生产。为了解决这个问题,我们将该炉进行了改造,经一段时间应用看,不仅取得了良好效果,而且有较高的经济效益。
Forging furnace is my factory forging workshop of the main equipment, but also the main energy-consuming equipment. The fuel used is heavy oil. Our factory forging workshop a total of seven forging furnace. As the furnace structure is unreasonable, refractory heat storage, insulation performance is poor, behind the oil nozzle, flue blockage, flue gas discharged from the furnace door, take away a lot of heat, front and rear door are open, a lot of cold air from the furnace Door into. Excess air coefficient up to 2 = 1.42 ~ 1.78. The heat balance test, these few forging furnace thermal efficiency is very low, only 6%. Therefore, serious energy waste, but also seriously affected the production. In order to solve this problem, we have transformed this furnace and, after a period of application, not only achieved good results but also achieved high economic benefits.
