1.Maintenance and treatment of burner ignition fault

 

If frequent ignition failures occur during the operation of the burner, the maintenance personnel should consider whether there is a blockage of the tubing. If it is found that the oil pipeline is indeed blocked after on-site inspection, the properties and characteristics of oil raw materials should be analyzed, and then the oil viscosity in the pipeline should be reduced to the normal level by means of oil replacement, heating and catalysis, so as to realize the unobstructed protection of oil pipeline. In addition, the electrode contact fault of the burner nozzle may also lead to the ignition failure of the burner. Therefore, the maintenance personnel should also be in the utility meter support, the nozzle of the combustion gun ignition test, and then implement a reasonable parameter adjustment, the distance between the nozzle and the ignition electrode control in 4 ~ 6mm.

 

If the burner goes out after ignition during operation, the maintenance personnel should check the filter to see if there is too much sediment in the internal environment of the filter, and then clean it through compressed air. At the same time, if the photocell is covered with a thick dust layer, the transmission stability of its optical signal will be affected, so that the remote control system will produce automatic oil-cutting action, and then the flame will be extinguished due to the lack of oil support. In this issue, maintenance personnel should not only do a good job of the photocell and the surrounding equipment environment clean, but also through the welding technology, the photoelectric cell's circuit connection quality optimization adjustment.

 

2.Maintenance and treatment of burner flame quality problems

 

The flame quality problems of burners used in steam injection boilers are mainly divided into three categories: flame combustion is not strong, unstable and not complete. Faced with the problem of weak flame burning, the maintenance personnel should check the operating quality of fuel pump to determine the continuous supply level of oil raw materials. At this point, if it is found that the fuel pump aging is more serious, the oil flow level is low, should be implemented in a timely manner to replace, clean and other treatment means, so as to ensure that the burner flame maintain sufficient fuel support; Facing the problem of unstable flame combustion, the maintenance personnel should conduct quality inspection from two angles of oil and air distributor.

 

On the one hand, the water content of the current oil should be analyzed, and appropriate dehydration treatment should be carried out. On the other hand, the operation parameters of the air distributor should be dynamically tested to check the stability of its wind pressure supply and adjust the guide vane and regulating ring accordingly; Faced with the problem of incomplete flame combustion, maintenance personnel should be committed to improving the proportion of air oil in the internal environment of the steam injection boiler, so as to provide more adequate oxygen support for oil combustion, so as to ensure the continuity of flame combustion, improve the economic application efficiency of the burner.
