Guide: 1. Daily work
(1) Check the function of the water level regulator: whether it can automatically fill the water and stop the pump.
(2) Inspection of flame monitoring.

1. Daily work

　　(1) Check the function of the water level regulator: whether it can automatically fill the water and stop the pump.

　　(2) Inspection of flame monitoring.

　　(3) Rotate, slide, lubricate the cam parts and wipe them.

　　 (4) Rinse the water level gauge 1-2 times (per shift), and operate according to the correct method until the water level gauge is flushed.

　　(5) Discharge 1-2 times (per shift).

2. Regular work

　　(1) Items to be checked every week

　　1) To stop the furnace at ultra-low water level, perform a furnace shutdown test (press the button on the B3 board, it should be able to simulate a water shortage and stop the furnace), or blow the sewage to check the function of the furnace at ultra-low water level.

　　 2) The safety valve is manually opened once and reset quickly.

　　3) The burner control system and the electric eye should be checked. The photocell of the electric eye should be taken out by hand, and the furnace should be shut down within 1 second; and the electric eye should be wiped.

　　4) Fill or replace valve packing; eliminate dripping.

　　5) Tighten bolts everywhere, especially the gas pipeline system, and check for leaks when necessary.

　　(2) Clean the filter on the gas pipeline once a month.

　　(3) The following parts should be maintained every six months

　　 1) Check the pressure gauge and clean the gauge tube, add distilled water when resetting.

　　 2) Maintain the water level electrode, after pulling it out, sand it with fine sandpaper.

　　3) To clean the flue, generally according to the exhaust temperature to decide whether to clean. Under normal circumstances, the exhaust gas temperature does not exceed 350°C (measured at the outlet of the boiler and the entrance of the flue). Too high means that the fouling has increased and the efficiency of the boiler has decreased, and it must be cleaned. The purpose of cleaning the flue is on the one hand for economic considerations, on the other hand it is also for safety considerations (the smoke fouling has poor heat conduction and is prone to local burnout). When cleaning and replacing asbestos gaskets, use the method of lap joints (to prevent fumes from running out), and apply graphite instead of lubricating oil.

　　4) After boiler repair or annual inspection, check that the manhole, head hole, hand hole nut can not be loosened, and check the motor rotation direction (from the fan end, it rotates counterclockwise).

　　(4) Check the safety valve once a year. Perform a comprehensive overhaul and maintenance of the boiler.
