搪瓷管预热器是安装在锅炉尾部，对进入锅炉前的烟气进行预热的受热面，可想而知，它的工作环境一定是十分严酷的，因此它的操作变得尤为慎重，尤其是发动期间，一个不小心就可能形成温度过风险表象，那么准确的空预器发动需求几步呢?
Enamel tube preheater is installation in the tail of the boiler, to enter the boiler flue gas to preheat the heating surface, it is conceivable that the working environment must be very harsh, so its operation become particularly careful, especially launched during, a careless may form temperature through senior risk representation, then accurate air pre heater launch needs several steps?
做好完善的发动前查看与预备→DCS画面调出空预器操作块，投入主动控制，电机长度发动按钮→开启发动马达电磁阀，承认空预器转向准确、声音正常→延时300s，空预器辅佐电机发动，查看电流是否正常→延时30s电磁阀关闭，气动马达退出运转→辅马达发动计时三分钟，空预器辅佐电机主动中止→辅佐马达退出，停反应回来→空预器主电机发动，查看电流正常与否→一起开启空预器进口烟气挡板以及一次风、二次风出口挡板，查看状况反应→顺控完成，查看空预器运转状况，正常后辅佐电机联锁。
To view and prepare to DCS picture out of the air preheater operation block perfect before launching, into active control, motor start button to start the motor on the length of the solenoid valve, air preheater, accurate to admit to delay 300s sound normal, air assisted pre heater motor, check current is normal to delay 30s solenoid valve closed pneumatic motor, auxiliary engine, running out of time three minutes, air preheater, motor assisted active suspension assisted motor exit, back to the main motor stop reaction air preheater engine, check current is normal or not, with open air preheater inlet gas baffle and a wind, the two air outlet baffle, check status reaction to complete sequence control, check the air preheater after normal operation condition, motor assisted interlocking.
看似费事的步骤，实际上投入主动控制后，设备会自行跟随程序发动，操作人员要做的即是时间观察各部位状况，确保空预器坚持发动状况，可以投入正常的使用。
Seemingly tedious steps actually put into active control, the device will automatically follow the program launch and operation personnel to do is observe the state of each part of time, ensure air preheater and stick to the best launch status can be put into normal use.
