After the shutdown of the waste heat boiler, in order to reduce the corrosion of the waste heat boiler, it is necessary to maintain the waste heat boiler. Because when the thermal equipment is shut down, the temperature and pressure in the water and steam system gradually decrease, steam condenses, air seeps into it from the imprecise parts of the equipment, and oxygen is dissolved in water, which is easy to cause corrosion in the waste heat boiler. So how should we properly carry out routine maintenance for waste heat boiler? Next, let's listen Henan horizontal waste heat boiler Manufacturer What did you say!
1. The safety valve shall be manually tested regularly and its working pressure shall be calibrated. Generally, it shall be calibrated once a year by the safety inspection department above the district and city level.
2. Regularly and irregularly inspect the boiler appearance and lifting lugs to prevent corrosion and cracking. Lifting lugs and hoists should be maintained and handled in a timely manner in case of lifting off.
3. Check the integrity of the three major accessories of the boiler every shift. The pressure gauge, water level gauge and safety valve are accurate, flexible and easy to use.
4. Henan horizontal waste heat boiler manufacturer recommends that the air tightness of the waste heat boiler system should be checked frequently to prevent leakage, bleeding, dripping and leakage. Check the water supply pipeline valves to make them flexible and easy to use, and check the flexibility of steam valves to make the gas supply system normal.
In order to ensure the normal operation of the waste heat boiler, the boiler will be maintained and overhauled once every six months or one year, and the major inspection will be conducted once every three years. The maintenance of waste heat boiler needs to be carried out according to some procedures and steps.
The maintenance of waste heat boiler is more important. A well maintained waste heat boiler can prolong its service life. Therefore, maintenance shutdown is an important measure for normal operation of boiler. It is of great significance to slow down boiler corrosion and prolong its service life.
