1. The boiler belongs to the pressure vessel. The furnace worker must be familiar with the “Trial Regulations for Steam Boiler and Pressure Vessels†promulgated by the State, and strictly implement the regulations on the management of boiler and pressure vessels.
2, the boiler must be managed by a special person, used by a special person, with a certificate to be employed, and listed on the date; during the work, there must be someone who has a fire, and the person is gone.
3. The boiler should be inspected thoroughly before operation to ensure that the running parts (such as motors, pumps, bearings, etc.) are flexible, and the lubricating parts are added to the operating parts; static parts (such as barometers, water level gauges, safety valves, hand holes, etc.) The work is normal; the valves are open and closed tightly.
4. Check the high and low water level and steam pressure automatic alarm sensitivity every shift; the flushing water level meter is 1-2 times per shift; the normal water level of the boiler should be between the highest and lowest positions of the water level gauge; the water level of the two water level gauges should be basically Consistent;
5. Check the pressure gauge once every shift, and rinse the pressure gauge elbow once every three days to ensure the smooth inside of the pipeline. Manually operate two safety valves to exhaust steam once a week, and pressurize two safety valves to automatically exhaust steam every month to prevent safety accidents caused by valve seat adhesion; keep the pressure in the furnace stable, and the maximum pressure should not exceed the allowable working pressure of the safety valve.
6. Regular sewage discharge, one discharge per shift, high water level and low load when discharging sewage; and timely descaling according to the scale of the drum and hand hole.
7. Check the manhole, hand hole, other pressure parts and economizer, superheater and other airtight conditions at any time, and find that the leakage and deformation are immediately corrected; check whether the indicator lights on the control panel are normal.
8, the furnace temperature takes ten to twelve hours to produce pressure. Starting from a small fire, gradually increase the firepower; the new furnace (referring to the new repair of the furnace wall and the newly installed boiler) can produce pressure after three to seven days of temperature.
9. Perform boiler water quality testing once a day; the alkalinity of the boiler should be 6-24mmol/L; the solid dissolved matter should be less than 3500mg/L; the hardness of feed water should not be higher than 0.03mmol/L.
10. The boiler water must be treated with water. The water treatment should follow the working procedures of “countercurrent, regeneration, washing and runningâ€.
11. After the salt pump is deactivated, clean the residual brine in the pump with clean water. In the winter, the internal water should be discharged, and the antifreeze work should be done at the same time.
