In the project of using the burner, the burner must be properly maintained. Only in this way can the life of the burner be extended. The following will talk about how to maintain the burner in order to prolong the life of the burner. Before maintenance, be sure to thoroughly inspect the burner and its components.
1. Fuel oil burner filter--For fuel oil burners, it is required to clean the basket filter between the fuel tank and the fuel pump. Regular cleaning of the filter keeps the fuel going to the pump and reduces potential component failure. Also check the filter for signs of excessive wear or damage Pressure Regulator Valve - Check the fuel pressure regulator or pressure relief valve to make sure the surface of the pin nut on the adjustable spigot is clean and removable. If the surface of the screws and nuts is found to be dirty or rusted, the regulating valve should be repaired or replaced. A poorly maintained fuel regulator valve can cause malfunctions in the engine. Oil exchange - first check the oil seal to ensure that the seal is intact and the internal pressure can be kept stable, and replace the damaged or leaking sealing elements.
If hot oil is used, it is necessary to make sure that all oil pipes are well insulated; if there are long oil pipes in the oil circuit, it is necessary to check whether the installation route is suitable. Replace damaged and poorly insulated tubing. Burners—For oil-fired burners, clean the "y" filter. Good heavy oil and residual oil filtration is the key to prevent injectors and valves from clogging. Check the pressure difference on the burner to see if it works normally and whether the oil pressure is within the appropriate range, so as to ensure that the fuel pressure can be read accurately after adjusting the burner. Adjust the protruding length of the atomizer on the oil nozzle, adjust and detect the low oil pressure switch. When using heavy oil, check the fuel heating and controls, and check the oil temperature switch on the burner stack. Consult the manufacturer for the required oil viscosity to ensure the normal operation of the burner, and regularly check whether the viscosity of the heavy oil or residual oil used meets the requirements. It is also necessary to clean and lubricate the oil valve connection. If the joint is sticky or too rough, repair or replace with suitable fittings. Finally, clean the grease nipple regularly according to the manufacturer's requirements.
2. Main gas source of natural gas burners - For burners that use natural gas as fuel, check the main gas source regulating valve to ensure that the line is intact. Do not adjust the regulating valve of the gas company. The gas company will assist in cleaning, maintaining and adjusting the regulating valve of the main gas source. If there is a sense wire, check it for damage. Filter——If a "" type filter is installed before the control valve, pay attention to cleaning. Control regulator valve - check the control regulator valve on the gas burner to see if the adjusting bolt is easy to adjust. Make sure all outlets and screens are not blocked. Burner - Check the gas pipe group to confirm whether the manual switch adjustment is sensitive and whether the valve handle is installed. Check to see if the barometer is working properly. Accurate pressure display is critical when adjusting gas burners. Turn the low air pressure and high air pressure switches to verify they are working. The connection of the air valve needs to be cleaned and lubricated. If the connection is sticky or too rough, it needs to be replaced with a suitable fitting. If the burner is installed with detachable pipelines, care should also be taken to clean them.
3. Burners for other fuels In addition to the above-mentioned fuels, there are many kinds of fuels for burners. The burner manufacturer can assist with providing maintenance schedules and procedures for burners operating on other fuels and establishing a maintenance schedule.
4. Don't ignore the oxygen supply. Once the oil supply system and burner maintenance plan has been determined, it is necessary to check the oxygen supply of the system. Oxygen supply to most burners is achieved by a blower or combination blower system.
Compressed Air - Many burners require compressed air to operate properly. First check whether the compressor can provide the pressure required by the burner. Clean all the filters on the pipeline, check whether there is any leakage in the pipeline, and repair the combustion/atomization air blower in time if there is any – check whether the inlet of the combustion or atomization air blower is equipped with a protective device, and whether the working environment meets the requirements. Repair leaks and damage to fan housings. Observe the operation of the blades to see if there is too much noise and vibration, and if so, it can be eliminated by adjusting the blades. Check the connecting pipe between the fan air outlet and the burner air inlet, and repair possible leaks. For belt-driven blowers, lubricate the bearings regularly and tighten the belt. Make sure the blower can produce the rated pressure and check the amperage. Clean and lubricate the air valve connection, adjust the valve to see if it runs smoothly. Main fan: Check whether the entrance of the main fan is equipped with protective equipment, whether the working environment meets the requirements, and repair the leak on the fan. Observe the condition of the blades when they are running to see if there is too much noise and vibration. If there are these phenomena, they can be eliminated by adjusting the blades. Make sure that the required wind pressure is achieved, clean and lubricate the connection, and adjust the air valve to see if it runs smoothly. Induced Air (Exhaust Air) - Determine whether the exhaust damper control is functioning properly and is set correctly. Lubricate the damper joint to see if it runs smoothly. Check the wear of the damper blades. Ignition device--clean the nozzle of the ignition device, and confirm whether the spark gap of the ignition electrode is normal. Components - Clean the flame detector, make sure it is properly viewed and cooled properly.
5. Coordination between the burner and other parts of the system. The maintenance program of the burner includes the debugging of the burner. A well-adjusted burner will be able to exert higher working efficiency. Portable Combustion Analyzers provide accurate information on how your burner is operating. Typical burner commissioning methods include fuel analysis and a series of adjustments that enable the burner to achieve operational performance while maintaining firing power. Basic commissioning can be completed in a day or less, before various tests are performed. Burner commissioning is performed after a complete burner maintenance program has been completed, especially during the early stages of plant commissioning. Commissioning of the burner should be carried out under normal conditions. Fuel samples should be taken from fuel drums to effectively and accurately describe burner operation. The commissioning of the burner is carried out according to the sampling information of the combustion flue gas. Any adjustments to air and fuel will affect smoke emissions, and smoke components can be studied to analyze combustion efficiency.
