Cause of the equipment accident(7)
(1) Burning out of the water jacket
1), the cause of the accident; 1) Due to the long-term use of tap water, the water jacket is scaled;
2) The demineralized water is interrupted and not detected in time;
3) False water level caused by water level meter failure;
2, Precautionary measures:
1) If you use tap water for a long time, you should remove the scale regularly;
2) Ensure sufficient demineralized water;
3) Inspect carefully and find problems in time;
(2) The fire layer descends and burns out the grate, bottom and skirt
1, Cause of the accident: 1) The level of furnace workers is not well controlled, resulting in the decline of the fire layer;
2) The equipment is defective, and the ash tray is leaking;
3) The ash tray is cut off and not found in time; 4) Excessive ash removal;
2, Precautionary measures:
1) The stoker should control the level in the furnace and not cause ash;
2) Ensure that there is sufficient sealing water in the ash pan;
3) Proper ash removal according to the level in the furnace;
(3) Bearing damage accidents of blowers and pressurizers
1, Cause of the accident: 1) After the fan is overhauled, the center is not right, resulting in bearing damage;
2) Bearing damage caused by vibration of the fan bearing;
3) Bearing damage caused by lack of oil;
2, Precautionary measures:
1) After the fan is overhauled, the center should be checked to be correct;
2) Lubricate the bearings regularly;
3) Inspect the equipment regularly, and switch it in time when problems are found
(4) Accidents of pipe network equipment in the plant area
1, Cause of the accident:
1) Natural rupture of gas pipeline explosion-proof causes gas shutdown in the whole plant;
2) Cracking of the weld caused by the fall of the gas pipeline;
3) Dump truck operation crashes into gas pipeline;
2, Precautionary measures:
1) Regularly inspect the pipeline for blast protection;
2) The bracket of the gas pipeline should be strong;
