Gas boilers start and stop frequently, what is the reason?

The gas boiler starts and stops abnormally, not only causing damage to the boiler itself, but also greatly increasing the fuel input and increasing the input cost. So, what are the reasons for the frequent start and stop of the boiler?

The on-site boiler operating load is low, the gas consumption is large and the gas is unstable, the pressure controller has small backlash or poor contact contact may cause the boiler to start and stop frequently. If you encounter relevant circumstances, you must deal with it in time:
       1. The operating load of the on-site boiler is not less than 30%, and the gas consumption is continuously stable; 2. Adjust the pressure return difference;
       3. Replace the pressure controller.

Note: If it is considered that the burner is not started and stopped frequently because the load is too small, the burner with proportional adjustment can adjust the start and stop of the burner by trimming the PID parameters and the set deviation.
