Fuel oil, gas and heat conduction oil furnace combustion fault treatment

Methods for dealing with combustion faults of gas-fired heat-conducting oil boiler, gas-fired heat-conducting oil furnace and gas-fired heat-conducting oil furnace.

After the operation of the gas-fired heat-conduction oil boiler for a period of time, there may be a variety of faults such as the furnace ignition.At this time it is necessary to check and analyze the gas-fired thermal oil boiler, find out the problem, and then to solve.

 

Changzhou shangneng boiler co., LTD. Analyzes and solves the two faults as follows.

 

Gas heat conduction oil boiler fault one: the furnace does not ignite.

 

(1) gas

 

Check whether the gas pipeline of the gas-fired heat-conducting oil boiler is unblocked;Ignition solenoid valve control line is intact;

 

Whether the ignition solenoid valve of the gas-fired heat-conducting oil boiler is operating;

 

After the ignition solenoid valve action of the gas-fired heat-conducting oil boiler, whether the valve has action.

 

Inspection method:

 

When the gas-fired heat-conducting oil boiler is running to ignition, the ignition solenoid valve terminal is measured to have 220V voltage, and the circuit problem is eliminated.After removing the ignition solenoid valve of the gas-fired heat-conducting oil boiler, the solenoid valve will return to action after energizing. The valve core can be visually opened to force the main valve bypass solenoid valve to open, the ignition gas is normal, and the possibility of fault of the gas-fired heat-conducting oil boiler and ignition solenoid valve can be eliminated.

 

(2) ignition of gas-fired heat-conducting oil boiler

 

Check the ignition electrode of the burner of gas-fired heat-conducting oil boiler and check whether the control line is intact;Whether the ignition electrode probe is sensitive.

 

Inspection method: when the furnace of gas-fired heat-conducting oil boiler runs to ignition, there is 220V voltage at the wiring terminal of ignition electrode. After the burner is removed, the wiring terminal of ignition electrode is normal to the wiring of ignition electrode.Observe carefully the ignition electrode and flame detector probe of gas-fired heat-conducting oil boiler have some scaling on them, and use the multimeter to measure the serious breakage of the probe. Therefore, it can be concluded that the reason for the non-ignition of the furnace is that the ignition electrode is scaling and the ignition signal is not available.

 

Changzhou shangneng boiler co., LTD. Solution: polish the surface of ignition electrode and flame detector probe with sand cloth until the smoke is completely removed. Test with multimeter.

 

Gas heat conduction oil boiler fault two: furnace ignition normal

 

The main valve of the gas-fired heat-conducting oil boiler burns normally after opening, and the fire goes out after turning into a big fire and opening the gale-door.

 

Failure analysis of changzhou shangneng boiler co., LTD. : gas;The main gas valve after disassembly inspection, the main valve solenoid valve and valve can work normally, the pressure regulator valve can also work normally, the main valve can not work normally, the front and rear end of the pressure regulator valve can be normal pressure, keep stable, to eliminate gas fault.

 

Fault of flame detector of gas-fired heat-conducting oil boiler;However, the hardware cannot tell the fault of the flame detector.If there is a problem with the flame detector, it will not continue to burn automatically, whether it is a small fire or a large fire, or the ignition phase.

 

Ratio of air and gas in gas-fired heat-conducting oil boiler;After the test, the manual fire can be burned, the ignition stage is normal.

 

The gas thermal oil boiler is normal, the flame detector is normal, and the ratio of gas is normal. Ann li said that the furnace should burn normally, and there is no other alarm should be normal combustion, so why can't the furnace work properly?

 

(1) the flame detector is installed in the correct position and works normally.

 

(2) the flame plate is installed correctly.

 

(3) correct ratio of air and gas.

 

Note: if one of the above three conditions is not correct, failure will occur.

 

Matters needing attention in operation of gas heat conduction oil boiler

 

1. Operate strictly according to the heating curve.

 

2. It shall not be put into use when the pressure difference is unstable.

 

3. When the furnace is stopped, the hot oil circulating pump can be stopped when the oil temperature drops below 80 ℃.

 

4. Ensure good circulation of thermal oil at high temperature.

 

5. When working normally, the heat conduction oil in the high tank shall remain at a high level, while the heat conduction oil in the oil storage tank shall be at a low level.

 

6. The oil output temperature shall not exceed the allowable operating temperature of thermal oil.

 

7. Do not flush the furnace chamber with water when the furnace is stopped in an emergency

 

8. Different types of thermal oil shall not be mixed.

 

9. The air outlet of oil storage tank shall be connected to the safe area.

 

10. The first heating rate must follow the heating curve.

 

11..Boiler room should be equipped with electrical appliances, oil fire equipment.
