For the fuel burner, the filter between the oil tank and the oil pump needs to be cleaned regularly, so as to keep the fuel reaching the oil pump smoothly and reduce the possibility of potential internal component failure. And also check whether there is wear or damage inside the filter Secondly, the pressure regulating valve needs to be maintained, and the regulating screw needs to be cleaned and maintained regularly. If it is not maintained regularly, it will hinder the work of the burner. Thus, the service life of the combustor is shortened.

   Thirdly, the oil pump shall first check whether its sealing is intact, whether the internal pressure remains stable, and whether there are damaged and leaking sealing parts. If hot oil is used, check whether the internal oil temperature remains stable and good. If there is a long oil pipe in the oil circuit, check whether the oil circuit is installed properly, so as to replace the oil pipe with poor insulation in time.

   For other types of burners, the filter nozzle and removable parts should be removed for cleaning to ensure the durability of the burner
