After people purchase the boiler, they must first read the instructions carefully, because only in this way can they understand the use of the boiler, and then they can better operate the boiler.But if you want to use the equipment for a long time, so the weekday maintenance work is indispensable, so we know how to do the steam boiler maintenance work?

One, daily maintenance methods

1 boiler feed water through qualified treatment, which is to prolong the life of the boiler, to ensure the safety of the operation of the important matters.

2. The water supply temperature should be close to the furnace temperature as far as possible, above 20℃.

3. Check, maintain and clean the low water level cutting device regularly.The water level controller is washed at least once a month and the water level gauge is washed at least once a day.Flushing water level gauge should be at the highest water level;After flushing, the water level should not be lower than the lowest safe water level. If one flushing is not clean, flushing can be repeated, and flushing can be done at the highest water level.4. It is necessary to carry out the sewage operation regularly, at least once a day (each shift), and check whether the sewage valve leaks due to the influence of dirt after the sewage discharge;If any, it will be excluded.

5 stop the furnace without maintaining the steam pressure, the boiler steam space will produce negative pressure and trapped air, so again fire combustion should first open the main steam valve.

6. Duct ash, will lead to smoke temperature rise, so that the efficiency of the boiler is reduced, the consumption of fuel is increased, so the front and back door cover should be opened regularly, brush or blow away the ash pipe.

7. The boiler safety valve will not be opened in the normal automatic operation of the boiler, but it is a necessary accessory to ensure safety.

Two, stop furnace maintenance and anticorrosion

1. After the boiler is stopped, in order to prevent corrosion in the pot, maintenance should be carried out.

2. Short-term maintenance.Wet maintenance method can be used;That is, after stopping the furnace, the furnace water is filled up and all the air is discharged.

3. Long-term maintenance.Dry maintenance method can be used, that is, after stopping the furnace, the furnace water will be released, open the lower hand hole, blow dry the pot water, and through the lower hand hole, into the desiccant, and should be replaced regularly, can start to check and replace every month - once, after three months.However, it should be noted that all the desiccant must be taken out before the boiler is started.
