Doing This on a Daily Boiler Maintenance Will Make the Boiler Last Longer

July 02, 2020

Daily maintenance of the boiler will ensure the consistent performance of the boiler. Ensuring the stability and quality of steam. And will lead the boiler to be used for another 10 years. We need to do the following 7 points:

  1. Inspection of burners

  2. Inspection of grates

  3. Inspection of furnace walls and doors

  4. Checking the thermal insulation

  5. Inspection of auxiliary equipment

  6. Inspection of security accessories

  7. The inspection of water treatment equipment.

These six points have the following requirements:

1. Inspection of burners.

Keep an eye on the burner head for normal operating sounds.

Burner head parts are normal or not.

Should keep the combustion head gas and oil lines clear.

The bearings of each rotating part should be well lubricated.

The bearing temperature should not rise more than 70℃.

Regularly clean the filter net on the gas and oil.

2. Inspection of grate

Check if the coal brake plate is rising and falling properly.

Check if the grate speed is normal.

Check whether the grate is damaged or not.

3. The inspection of the furnace wall and furnace door.

Always check whether the furnace chamber and flue, furnace door, watch fire hole and manhole are well sealed.

If finding the phenomenon of steam leakage and water leakage, it should be repaired promptly.

4. Inspection of the insulation layer

The insulation may fall off if it is used for a long time, this will lead to losing heat and increasing the temperature of the boiler room, which may sometimes cause burns People. Therefore, the discovery of the insulation layer off: must be dealt with in a timely manner.

5. The inspection of auxiliary equipment

Whether the valve is leaking.

Whether the water pump is supplying water properly.

Whether the oil pump oil pressure is normal.

There are packing seals at the valve stem and stuffing box.

If it is a coal-fired boiler you need to check the furnace air pressure and make sure it is negative. If it is not, you need to adjust the airflow of the forced draft fan and induced draft fan.

Problems found in a timely manner.

6. check the safety accessories

Flush water level gauges and pressure gauges regularly. Keep the surface clean for easy reading.

The safety valve should be lifted and put down periodically by hand to prevent corrosion and jamming.

Once the safety accessories are damaged, they must be repaired or replaced immediately.

7. The inspection of water treatment equipment

Frequently check the water treatment equipment (water softener, deaerator tank, automatic dosing pump), monitor the operation of water quality.

Once the water quality is not up to par, you should immediately find the cause and replace or repair it.
