Key points of safe operation of pulverized coal boiler system:
1. The boiler system must be technically managed and operated by a special person, and the on-site management guidelines that conform to the "Boiler Safety Skills Supervision Regulations" must be formulated. Operators must hold a qualification certificate before they can work.
2. The boiler room is classified as a flammable and explosive place, and the casual personnel are not allowed to enter without permission. The viewing personnel must be accompanied by the stoker, and it is forbidden to tamper with any boiler equipment.
3. A boiler shall be operated and monitored by at least two persons, and the principle of one person to operate and one person to supervise shall be implemented.
In the boiler room, a special person is set up for inspection, and in case of leakage or leakage, contact the operation and maintenance personnel in time, and take measures to eliminate hidden dangers. During the operation of the boiler, the inspectors should not walk within the discharge range of the explosion-proof door to prevent accidental occurrence.
4. After the boiler is accidentally extinguished, the interlock protection device should be activated immediately. Before re-ignition, the purging procedure should be strictly implemented to ensure that the furnace ventilation and purging time are not less than 3 minutes. If necessary, the purging time can be extended and the furnace Manual viewing. After the normal ceasefire and before starting the furnace again, in addition to the furnace purging procedure, the ash accumulation in the furnace should also be checked manually, and manual sorting should be carried out if necessary.
5. During the normal operation of the boiler, avoid unnecessary frequent start and stop operations. When it is unavoidable, the fourth rule above should be strictly implemented.
6. The operator should judge and check the status of the boiler ash and coking according to the change of boiler resistance and on-site monitoring, and arrange it in time. If necessary, the boiler should be stopped for thorough cleaning.
7. In order to ensure the safe, economical and stable operation of the boiler, it is forbidden to operate the boiler under a load of less than 30% for a long time.
8. During the coal loading operation in the pulverized coal boiler silo, a special person should be responsible for monitoring the coal loading process so as to respond to emergencies at any time. The whole powdering process is strictly carried out in accordance with the "Coal Powder Silo Operation Regulations". Open flames are prohibited within 10m around the pulverized coal bunker. Make sure the pulverized coal silo warning signs are clear and clear.
9. Open flames are prohibited in the pulverized coal silo work room and the fan operation room, and dust shall not be raised during cleaning, and special vacuum cleaners should be used for cleaning.
10. For other detailed operating procedures and precautions, please refer to the instruction manual. When the boiler manufacturer conducts boiler operation and operation training, the stoker personnel should study and record carefully. In the future operation process, the key to the safe operation of each link such as coal grinding equipment, pulverized coal storage equipment, and boiler equipment should be thoroughly understood to prevent potential safety hazards.
