is closed; 2. Check whether there are sundries in the electric field, and pick them out immediately if any; 3. Check whether the manhole door of the dust collector is closed and whether there are people or other sundries in the rectifier room. 4. Check and adjust the high-voltage rectifier device

1. The work before operation is completed, all safety measures are perfect, and relevant personnel have been in place; 2. Each heater shall be put into operation at least 8 hours before starting to ensure the dryness of the ash hopper and all insulators (insulating porcelain bushing, electromagnetic rotating shaft) and prevent any damage caused by condensation and leakage. Check whether the current of each heating system is normal; 3. Open the Wind Damper on the inlet and outlet flue (excluding the inlet and outlet together with the flue); 4. Start the fan; 5. Preheat the electric field and steam to eliminate the moisture on the internal parts of the electrostatic precipitator. The preheating time depends on the temperature and humidity of the gas in the electric field. Generally, the temperature at the outlet of the final electric field can reach above the dew point; 6. Start the ash discharge system; 7. Start all rapping mechanisms; 8. Start all functions of the rapping system to make the alarm and safety interlock, temperature measurement and temperature control device, ash level detection and ash discharge and conveying in a controllable operation state
