How to debug the boiler burner and how to do it?

1. Take the multimeter to test whether there is a short circuit in the control circuit without power;

2. Power on, manually start the fan and disconnect it to judge whether the fan is rotating positively;

3. Start the burner and observe whether the damper is normal;

4. After successful ignition, observe the chimney to see if there is black smoke, and adjust the air distribution or fuel appropriately;

5. Turn into a large load, observe whether there is black smoke, and adjust the air distribution or fuel;

6. After the shutdown, ignite and turn the fire many times to observe whether there is a flameout;

A lot of the debugging of the burner can not be explained clearly in one or two sentences, and the steps are roughly the same, but the process of troubleshooting is ever-changing, and it can only be accumulated in daily work.

Look at the operating instructions for burners with different brands. The debugging method is also different.

The manual has a method for adjusting the initial burner start-up.

If you don't understand, please consult the dealer.

Suggestion: It is best to debug the burner by the professional and technical personnel of the regular dealer.

Otherwise, the debugging is not good, the combustion is insufficient, and the energy is wasted, which is much higher than the cost of you asking someone to debug.

Unprofessional debugging also has potential safety hazards.

1.Fan test (single test motor, with load). 2.

Air leakage test (positive pressure, negative pressure). 3.Cold state test.

4.Hydrostatic test. 5.

Valve opening and closing test. 6.Protection test.

7.Oven. 8.

Cooking stove. 9.Blowpipe.

10.Steam tightness test. 11. Safety valve commissioning.

Before ignition, the gas pipeline tightness test must be done.

1. Inspection before commissioning of gas engine.

Check whether the gas is in place, whether the gas pipeline is clean and smooth, and whether the valve has been opened.

Whether there is pipeline leakage and whether the pipeline installation is reasonable.

Drain the pipe in front of the gas valve to ensure that there is no mixed air in the pipeline, and the drain pipe should be connected to the outside.

2. Internal inspection of gas burner.

Whether the burner head of the burner is well installed and adjusted.

Whether the motor rotates in the correct direction.

Whether the external circuit connection meets the requirements.

According to the circuit situation, the cold state simulation of the burner is carried out to observe whether the various parts of the equipment in operation are normal and whether the flame detection and protection part is normal.

When starting to debug the burner, we must do a comprehensive inspection of the hole, so as to ensure safety, if the debugging fails, then we should do a second comprehensive inspection, so as to ensure that one can be perfect.

1.The burner is installed on the furnace, and if there is black smoke during combustion and debugging, gradually open the large air door; If there is white smoke (water vapor), gradually close the small damper; Dampers are small to smoke-free.

2.After the burner burns normally, turn off the power for a few minutes, stop for a few minutes and turn it on again to observe whether its ignition and combustion are normal. If the alarm light is on after starting the burner, you need to wait at least 20 seconds and press the reset button again to restart.

3.If the flame length is very short and the color is red, then adjust the damper to close until the flame is yellowish and faintly dazzling, its ignition force is strong and powerful, and the flame length is moderate.

4.If the color of the flame is red, its ignition strength is poor, and the spitting speed is small, then adjust the damper to continue to open until the flame is yellowish and faintly dazzling.

5.Before the burner is started, the adjusting damper under the body is slightly opened (the opening is 1 3 of the full opening), and then the machine is turned on, and when the flame is ignited, carefully observe its color, the ignition power of the flame and the initial velocity of the jet flame.

Electric boilers need to be tuned according to their own required temperature, usually set to 20 degrees Celsius. Electric boilers are mainly used for room temperature control and water temperature control.

For room temperature control, the temperature probe can be set indoors or in the living room, the height should be controlled at about one meter, and the temperature can be set between 18 and 22. If it is used for water temperature control, it is necessary to set the temperature according to the different types of radiators.

What should be paid attention to when using electric boilers.

1. Installation and placement points. When the electric boiler is installed, the installation point of the gas pipeline must be selected, and it must not be installed in a closed cabinet for the sake of the beauty of the room. Because if a leak occurs during use, it is very difficult to detect, and it is very easy to occur once it encounters an open flame.

2. It shall not be mixed with chemical agents. In the process of using electric boilers, chemicals must not be mixed into it, especially the dust bend is antifreeze, otherwise it will affect its system. In fact, the current electric boilers are equipped with a freezing system, no need to add antifreeze, for people who go out for a long time, if you are afraid that the electric boiler will be frozen, you can discharge all the water in it, and then close the system.

The commissioning of the boiler is of great significance to the safety production of the boiler, therefore, it is very important to do a good job in the commissioning of the boiler, after the completion of the boiler assembly work, the commissioning of the boiler must be carried out according to the specific situation of the boiler, and the problems are found and solved in time to ensure that the boiler can be used normally.

Prepare for boiler commissioning.

When carrying out the boiler commissioning work, it is necessary to make preparations, choose the appropriate commissioning method, optimize the commissioning scheme according to the specific environment where the boiler is located and the specific situation of the boiler itself, and ensure that the commissioning scheme is reasonable and correct. At the same time, it is necessary to reasonably arrange the commissioning staff, check the various tools required for the commissioning work, and ensure that the personnel can be in place in time and the tools are intact, so that these preparations can provide guarantee for the orderly progress of the boiler commissioning work.

Do a good job in the safety assurance of commissioning work.

The commissioning of the boiler is very important, and there are certain risks in the commissioning process. The existence of this risk requires boiler commissioning personnel to have certain professional knowledge and good professionalism, and can find problems in time during the boiler commissioning process, so as to better solve the problem, reduce the occurrence of potential safety hazards as much as possible, and ensure the safety and smooth progress of boiler commissioning.

The main content of boiler regulation is the load of the boiler. The quality of the steam as well as the economy and safety of the boiler operation.

In order to ensure the safety and economy of the operation of the boiler unit, the boiler should be strictly monitored and adjusted as necessary during operation, and the operating personnel should have a high sense of responsibility and high operation skills.

1. Keep the evaporation capacity of the boiler within the rated value to meet the needs of users.

2. According to the needs of the load, balance the water supply and maintain the normal drum water level.

3. Maintain normal steam temperature and pressure, and stabilize system parameters.

4. Keep the quality of superheated steam and saturated steam qualified.

5. Maintain a good combustion state and improve the thermal efficiency of the boiler.

6. Ensure the safe operation of the boiler unit.
