Description :

　　Normal operation

　　During normal operation of the boiler, it is required to ensure that the water level in the drum is normal, the steam pressure is stable, the boiler room is kept clean, handover work is done well, instrument monitoring is strengthened, the boiler operation is safe and reliable, accidents are prevented, and the boiler operator regularly summarizes operational experience to continuously improve the operating level. At the same time, it is necessary to keep records of operation, shift handover, and water quality testing.

　　1. Water quality requirements:

　　The water quality of the boiler should comply with the requirements of GB/T1576-2008 "Industrial Boiler Water Quality".

　　2. Water level in the pot:

　　Regularly pay attention to changes in the water level in the pot, keeping it within the normal water level range of ± 40 millimeters, and not exceeding or falling below the safe water level. The water level in the water level gauge generally has a slight shaking phenomenon. If the water level is stationary, there may be blockage in the water level gauge, and immediate flushing and inspection should be carried out.

　　3. Water level gauge:

　　At least once per shift, the water level gauge should be flushed to keep the glass plate of the water level gauge regularly clean and ensure that the water level is clear, correct, and reliable. If the gasket of the glass plate is found to be leaking steam, the gasket should be tightened. If the glass plate is blurry or the water level line cannot be seen clearly, it should be replaced even after flushing. Each boiler is equipped with two water level gauges. If one of them is damaged, it should be repaired immediately. If both are damaged at the same time, the boiler should be temporarily shut down immediately until one of the water level gauges returns to normal before continuing.

　　4. Water supply equipment

　　Check whether the water supply pump is normal. It should be briefly driven and inspected during the shift handover. If there is a malfunction, it should be repaired immediately.

　　5. Steam pressure

　　Regularly pay attention to pressure changes, try to maintain stable pressure inside the pot shell, and do not exceed the allowable working pressure.

　　6. Pressure gauge:

　　The pressure gauge bend should be flushed once per shift to check if the pressure gauge is normal. If any damage is found, the boiler should be immediately shut down for repair or replacement. To ensure the accuracy of the pressure gauge, it should be calibrated once a year. If the reading exceeds the allowable error, it should be repaired or replaced. Pressure gauge bends should have anti freezing measures in winter to prevent inaccurate pressure readings.

　　7. Safety valve:

　　Pay attention to whether the function of the safety valve is normal. In order to prevent the valve core and seat from sticking, regularly pull the lifting handle of the safety valve and conduct an exhaust test.

　　8. Discharge valve: Refer to Article 8 "Discharge" for regular discharge.

　　9. Exhaust: If the hot equipment temporarily does not use steam and the main combustion equipment in front needs to operate normally, the exhaust valve can be opened to discharge the excess steam. If a bypass flue is set up, the bypass flue can also be opened and the flue entering the boiler can be closed.

　　10. Shift handover

　　In order to ensure the safe, reliable, and economical operation of each shift, the stoker should effectively carry out the following tasks during the shift handover:

　　(1) The incoming stoker should arrive at the boiler room before the designated time and prepare for the shift.

　　(2) The shift change stoker should achieve the following:

　　a、 Boiler steam pressure and water level are normal;

　　b、 Stable smoke circulation;

　　c、 All mechanical equipment is operating normally;

　　d、 Boiler accessories (including pipelines, valves, instruments) are safe, sensitive, and reliable;

　　e、 The boiler room is clean and tidy, with bright lighting.

　　(3) Both parties involved in the shift handover must ensure thorough and serious handover, and record the situations and issues encountered during the handover in the operation log book.
