Combustion engine is widely used in industrial equipment. As a special equipment, it is necessary to pay attention to maintenance matters in daily use in order to ensure the safe operation of the equipment. The safe use of combustion engine is very important!

According to the combustion characteristics of the gas in the furnace, the safety control requirements mainly include pre blowing, automatic ignition, combustion state monitoring, protection of non ignition point of the burner, flameout protection, high and low limit protection of gas pressure, insufficient air pressure protection, power-off protection, measures to prevent gas leakage accidents, etc. taking the burner often used in the boiler as an example, what should be paid attention to in daily life:

1、 Basic knowledge:

1. Keep the boiler environment clean.

2. The periphery of the burner shall be kept clean to prevent dirt from being sucked into the burner.

3. When checking the burner, first disconnect the power supply and fuel switch;


2、 Relevant matters to be checked during startup:

1. The main switch of power supply has been connected, and the switching power supply is in continuous phase;
2. The gate valve on the gas pipeline and heating system pipeline is open;
3. The natural gas pressure is within the pressure range required by the combustion engine;
4. The regulating plate on the boiler exhaust duct must be open;



3、 If the burner does not operate:

1. Check whether the gate valve on the gas supply and branch pipeline has been opened;

2. Turn off the operation button and check the relevant burner parts to ensure that the relevant accessories are normal.

4、 After ignition, the combustion engine does not ignite:
1. Grasp the starting condition of the combustion engine, and the forced operation of the combustion engine must not be allowed;
2. Do not ignite the burner before the residual gas in the boiler is exhausted;

3. If the combustion engine can not be ignited all the time, technical professional staff should be invited to deal with it.

5、 During boiler blowing in summer:

1. Disconnect the main switch power supply and the gate valve on the natural gas pipeline. If the burner is repaired in a short time, it should also be the same.

6、 Frequently asked questions:

1. When the burner is working, check whether the newly installed chimney is firm and can not cause vibration and other abnormalities
2. Whether the newly applied ignition equipment can ignite natural gas;
3. If the combustion engine fails to ignite and needs to be restarted, it must wait about ten minutes until the residual gas in the furnace is exhausted. Prohibit ignition several times.

In principle, the burner can be a kind of equipment that can ignite chemical substances and convert them into energy. Therefore, when applying this kind of machinery and equipment, we must pay attention to safety, do a good job in the inspection of machinery and equipment before application, and keep the common problems in mind, which will also increase the service life of the burner.
