Questions&Answers

(1) External chain failure, external temperature or pressure control did not reach the lowest start limit; Check the temperature or pressure setting.

(2) The program controller hitch and was not reset right, needs to be reset again.

(3) The fan motor is protected from overheating, rest the thermal relay.

(4) Check whether the start button of the control cabinet is in good condition.

(5) Circuit failure, check whether the start signal and voltage insurance work..

1. The external temperature or pressure control has not reached the loweststarting limit.

2. The internal interlock of the burner fails or the wind pressure switch is abnormally

3. The program controller failed to reset.

4. Fan motor overheating

5. Circuit failure

1. The distance between ignition electrodes is too long, adjust the electrode spacing.

2. The equipment is polluted,needs to be

3. The ignition electrode or circuit is grounded, to eliminate other connections and replace the damaged electrode or cable.

4. If the ignition transformer fails, replace it.

When igniting, the flame oxygen content is too low, which leads to unstable combustion, and the burner will surge when running at low load, which can be solved by increasing the air volume.

1. Flame detector

2. Gas solenoid valve

3. Ignition transformer

4. Oil pressure sensor

The filter is used to filter out impurities and oil in the fuel gas to ensure the normal operation of the burner valve group. According to the quality of gas, the filter should be cleaned regularly. If wet gas is used, the air inlet valve can be closed periodically, the valve under the filter can be unscrewed, and the settled liquid can be discharged into a special container for dumping. Then, the upper cover can be removed, and the fastening screws of the filter screen can be loosened to remove the filter screen and the attached dirt. If clean dry gas is used, the cleaning cycle can be extended.

1、Surface of burner shell and pipeline.

2、Burner flame mixing cone

3、Ignition electrode of burner

4、Burner valve group filter

1、Adjust the inner diameter of the coal pipe and change the outlet wind speed, so as to change the thrust of the coal pipe.

2、Adjust the proportion of internal and external wind, the internal wind is swirl wind, which makes the flame shorter and thicker; The external wind is axial wind, which makes the flame thinner and longer.

3、Adjust the total amount and pressure of primary air to ensure that the coal injection pipe has enough thrust.

4、Adjust the butterfly valve opening of central air to strengthen the internal and external back flowof high-temperature gas in the burner.

1、The controller must be installed in a ventilated environment.

2、The ventilation openings in the suction grid part and the installation space cannot be blocked ornarrowed.

3、There should be no explosion or firepossibilitieson the installation site.

4、Before installation, the internal space of all fuel delivery pipelines shall be carefully cleaned.

(1) The fuel pipe diameter is too small.

(2) Air is mixed into the fuel pipe.

(3) Contamination of oil filter

(4) The distance between the oil tank and the burner is too large or there is external leakage.

Possible reasons:

(1) The ionization current is unstable

(2) Change the position of ionization electrode and flame plate, and check the connection line.

(3) Uneven adjustment of gas-air mixture

(4) Re-adjust the gas-air mixture.

(5) Ignition spark affects ionization current.

(6) Replace the phase line and neutral line of the primary coil of ignition transformer.

Possible reasons:

(1) The pressure switch contact is not connected to the running position (the air pressure is too low)

(2) The blower is polluted and the hot relay moves.

(3) The gas burner motor rotates in the wrong direction.

Solutions:

(1) Adjust the pressure switch correctly and replace it if necessary.

(2) Cleaning equipment

(3) Pole change of power supply
