How to extend the service life of burner

　　In the use of burner engineering must be appropriate maintenance of the burner, only in this way can extend the life of the burner, the following will talk about how to maintain the burner, in order to extend the life of the burner.Be sure to thoroughly inspect the burner and its components before maintenance.7XIBoiler Burner

　　1. Oil-type burner filter -- for oil-type burner, it is required to clean the basket filter between the oil tank and the oil pump.Regular cleaning of the filter keeps fuel flowing to the pump and reduces the potential for component failure.Also check the filter for signs of excessive wear or damage to the pressure regulator - check the fuel pressure regulator or pressure reducing valve to determine if the locking nut on the adjustable bolt has a clean and removable surface.If the surface of the screw and nut is found dirty or rusted, repair or replace the regulator.A lack of maintenance of the fuel control valve may cause the burner to malfunction.Oil pump - check the oil pump to determine if the seal is intact, internal pressure is stable, and replace damaged or leaking seal elements.If hot oil is used, make sure all tubing is well insulated.If there is a long oil pipeline, check whether the installation route is suitable.Replace damaged and poorly insulated tubing.Burner - for oil burner, clean "y" filter.Good filtering effect of heavy oil and residual oil is the key to prevent plug of nozzle and valve.Check the pressure difference on the burner to see if it is working properly and the oil pressure is within the proper range, so that the fuel pressure can be accurately read after adjusting the burner.Adjust the extension length of the atomizer on the nozzle, adjust and detect the low oil pressure switch.When using heavy oil, check fuel heating and controls and check oil temperature switches on burner tube sets.Consult with the manufacturer about the required oil viscosity to ensure the proper operation of the burner, and regularly check whether the viscosity of the heavy oil or residual oil used meets the requirements.Cleaning and lubricating valve connections is also necessary.If the joint is sticky or rough, repair or replace the fitting.Finally, clean the nozzle regularly according to the manufacturer's requirements.7XIBoiler Burner

　　2. Natural gas burner main gas source -- for natural gas fueled burners, check the main gas source regulator to ensure line integrity.Do not adjust the gas company's control valve, the gas company will assist in cleaning, maintenance and adjustment of the main gas source control valve.If there is a sensor circuit, check it for damage.Strainer - if a "y" strainer is installed before controlling the regulator, clean carefully.Control control valve - check the control control valve on the gas burner to see if the control bolts are easy to adjust.Make sure all exits and screens are not blocked.Burner - check the gas line set to confirm that the manual switch adjustment is sensitive and the valve handle is installed.Check whether the barometer is working properly.Accurate pressure indication is critical when adjusting gas burners.Rotate the low and high pressure switches to confirm their working status.Air valve joints shall be cleaned and lubricated, and suitable fittings shall be replaced if joints are sticky or too rough.If the burner is installed with a detachable line, care should also be taken to clean it.7XIBoiler Burner

　　In addition to the above mentioned fuels, there are many other types of fuels used in burners.Burner manufacturers can assist in providing maintenance schedules and procedures for burners using other fuels and determine the best maintenance plan.7XIBoiler Burner

　　4. Do not ignore oxygen supply once the maintenance plan for the oil supply system and burner has been established, check the oxygen supply for the system.Most burners supply oxygen through a single fan or a combined fan system.7XIBoiler Burner
compressed air - many burners require compressed air to function properly.First check that the compressor provides the pressure required by the burner.Clean all filters in the pipeline, check if there is any leakage in the pipeline, and repair the combustion/atomized air blower in time if there is any -- check whether the combustion or atomized air blower inlet is installed with protective devices and whether the working environment meets the requirements.Repair leakage and damage to fan housing.Observe the operation of the blade to see if there is too much noise and vibration, if there is by adjusting the blade to eliminate.Check the connection between the fan outlet and the burner air inlet for possible leaks.For belt-driven blowers, regularly lubricate the bearing and tighten the belt.Determine that the blower can generate rated pressure and test the current intensity.Clean and lubricate the air valve connection, adjust the valve to see if the operation is smooth.Main fan - check that the inlet of the main fan is protected, the working environment is up to the requirements, and repair leaks on the fan.Observe blade operation to see if there is too much noise and vibration, if there is such phenomenon can be eliminated by adjusting the blade.Determine whether the required air pressure is met, clean and lubricate the connection, adjust the air valve to see if the operation is smooth.Induced air (exhaust air) - make sure the exhaust damper control is working properly and is set correctly.Lubricate the valve connection to see if it runs smoothly.Check valve blade wear ignition device - clean ignition nozzle and confirm spark gap of ignition electrode is normal.Parts - clean the flame detector to determine if it is in the right place to observe and cool properly.7XIBoiler Burner

　　5. The maintenance program of the coordinated burner for the burner and other parts of the system includes the commissioning of the burner. A well-tuned burner will be more efficient.Portable combustion analyzer can provide accurate information of burner operation.Typical burner debugging methods include fuel analysis and a series of adjustments that allow the burner to perform optimally while maintaining combustion power.Basic debugging can be done in a day or less and before various tests are performed.It is very important to debug the burner after the complete maintenance program is completed.Commissioning of the burner should be carried out under normal conditions.The fuel sample should be extracted from the fuel tank in order to describe the burner effectively and accurately.The adjustment of burner is based on the sampling information of combustion smoke.Any adjustment of air and fuel oil will affect the emission of flue gas. The composition of flue gas can be studied and the combustion efficiency can be analyzed.The combustion products and their causes are listed in the following table.Regular burner maintenance procedures are necessary to avoid shutdown and extend the life of the combustion system.Combine the above steps with the recommendations of the burner manufacturer to determine an effective maintenance program that will not only reduce the cost of maintenance due to downtime, but also improve combustion efficiency and save fuel costs.7XIBoiler Burner

　　In the process of using the burner must pay attention to maintain the burner, only in this way, can be a good role of the burner, so as not to delay manpower and material resources, waste time is a waste of money, in the process of use, must regularly maintain the burner, often a good method, is the way to save money.7XIBoiler Burner
