我市乳品厂一台KZL4-13的蒸汽锅炉,由於锅炉是属新装的,投入运行时间不长。锅炉在投入运行初期,设备的出力相当不错,在压力参数为1MPa(10kgJ/cm~2)的状况下,蒸发量通常可达4.5—5吨/时左右,大大满足了该厂以白天班生产为主的用汽负荷,锅炉深受用户的欢迎。由於锅炉处於白天负荷,晚间经常停炉备用的状况,这样运行半年之后,在同样的操作条件下,渐渐发现炉膛严重地烧正压现象,火焰烧坏右侧第一个加料门及炉墙,
Our city dairy factory a KZL4-13 steam boiler, because the boiler is a new installation, put into operation not long. In the early stage of operation of the boiler, the output of the equipment is quite good. Under the condition of the pressure parameter of 1MPa (10kgJ / cm ~ 2), the evaporation capacity is usually up to 4.5-5 tons per hour, Based on the steam load, boilers welcomed by users. Since the boiler is under daytime load, it is often shut down in the evening and ready for use at night. After six months of operation, under the same operating conditions, it is found that the furnace burns a serious positive pressure and the flame burns the first feeding door and furnace wall on the right side ,
