,锅炉停运后要认真进行漏风试验,及时消除漏风点。对产品所在的膨胀点检查要做到使其在运行中不膨胀受阻引起钢管断裂漏风。第二,产品的入口风温控制在20℃以上,可在送风机、一次风机进入设备前风道中加装暖风器系统。第三,没有采用暖风器系统的设备,冬季时要根据室外气温情况开大送风机,确保入口风温。
First, after the shutdown of the boiler to carry out air leakage test, timely elimination of air leakage points. To be able to do in the operation of the expansion pipe leakage caused by fracture not blocked expansion points where the inspection of products. Second, the product of the inlet air temperature control in more than 20 DEG C, in fan, a fan into the air before the device installed air heater system. Third, there is no use of the air heater system equipment, winter to according to the outdoor temperature on large blower, ensure that the inlet air temperature.
其次,在锅炉负荷变化时,可根据烟温高低相应进行调整。要加强巡回检查发现送风机、一次风机风道振动,及时进行运行调整,合理避开送风机、一次风机的喘振点。针对这些要注意以下方面:
Secondly, in the boiler load, can be adjusted according to the level of smoke temperature. To strengthen the tour of inspection found blower, a blower duct vibration, timely adjustment of the operation, reasonable avoid fan, a fan of the surge. For these should pay attention to the following aspects:
锅炉送风机已采用液偶调节尾部烟道部位吹灰工作要每班进行一次冷态点火开炉投粉前必须在尾部烟道烟气温度上升到400℃以上再观察设备的各部温度锅炉投粉后煤油混烧时间不得过长锅炉正常运行中,炉膛负压要趋于合理在保证完全燃烧的前提下,合理降底过量空气系数,维持低氧燃烧。
Boiler draft fan has the liquid pair conditioning flue at the tail part of the blowing ash work to be conducted once per shift cold ignition start-up before ing powder must be in tail flue gas temperature rises to more than 400 DEG C and then observe the equipment of the temperature boiler powder feeding after mixed combustion of coal and oil time not too long the normal operation of the boiler, furnace negative pressure will tend to be reasonable in order to ensure the complete combustion of the premise, reasonable lower excess air coefficient, maintaining low oxygen combustion.
