    锅炉启动前应进行哪些试验:
    What tests should be conducted before the boiler starts:
    1)锅炉风压试验检查炉膛、烟道、冷热风道及制粉系统的严密性,消除漏风点。
    1)boiler air pressure test to check the furnace,flue,cold air duct and the strict tightness of the system,eliminate the leakage point.
    2)热水锅炉水压试验锅炉检修后应进行锅炉工作压力水压试验,以检查承压元部件的严密性。
    Boiler work pressure test should be carried out after boiler water pressure test,to check the strict tightness of the pressure component.
    3)连锁试验所有连锁装置均需进行动作试验,以保证生产过程稳定,防止误操作,能迅速排除故障。
    3)all interlocking devices in the chain test need to carry out an action test to ensure that the production process is stable,prevent the wrong operation,and can quickly eliminate the fault.
    4)电动阀、调节阀试验进行各电动阀、调节阀的全开和全关试验,观察指示灯的亮、灭是否正确;电动阀、调节阀的实际开度与表盘指示开度是否一致;限位开关(终点开关)是否起作用;全关时是否有漏流量存在等。
    4)the electric valve,the control valve test shall carry out the whole operation of the electric valve,the adjusting valve and the whole test,and observe the light of the indicator and the correctness of the signal.The actual opening of the valve,the adjusting valve and the dial indicates whether the opening is the same.Whether the limit switch(endpoint switch)works;If there is any leakage flow in the whole pass.
    5)转动机械试运行电动机绝缘试验合格,全部转动机械试运行合格;具有双吸、双送风机者,应进行同期试验,以保证风机运行时负荷一致。
    (5)turning mechanical test running motor,all the mechanical test run is qualified.With double suction and double blower,the experiment should be carried out for the same time to ensure that the fan is at the same time.
    6)冷炉空气动力场试验如果燃烧设备进行过检修或改造,应根据需要进行冷炉空气动力场试验。
    6)if the combustion equipment has been repaired or modified,the air power field test should be carried out according to the need.
