1 bearing high temperature
2 bearing high vibration
3. Blower A fuel supply / return to the oil temperature is high.
4. Blower low oil pressure.
Deal with
1, reducing the output of the blower A increases B and efforts to prevent load imbalance occurs surge.
2, inspection place check blower operation, the oil system, oil pressure, oil temperature, taking into account net differential pressure, the pump is running normally, the bearing is damaged, the vibration is normal.
3, according to the total air volume / oxygen situation, adjust the unit load.
4. Contact the Assistant concerned about the turbine / electrical.
5, reporting the value of contact maintenance.
6. Check the air flow, oxygen furnace negative pressure is normal, normal boiler combustion and fire detection is normal.
7, checks / normal the parameters of the induced draft fan.
8 to identify the occurrence of a high temperature fan bearings, and determine the need to stop the delivery of fan A.
9.To maintain master / re-gas, the wall temperature to normal, the normal superheat, if necessary, manually adjust the coal / water ratio, the flue baffle.
10, comprehensive inspection of the furnace, mechanical, electrical systems are operating normally.
