[0002] A burner is a general term for a device that sprays fuel and air in a certain way for mixed combustion. A burner that uses fuel oil as fuel is called a fuel burner. The quality of the fuel oil also affects the combustion quality of the burner. Most of the existing burners are not equipped with a fuel oil monitoring and control system. Even if a few burners are equipped with an oil temperature monitor, it can only be used to monitor whether the heating temperature of the fuel oil is appropriate, and cannot monitor the water content, suspended impurities, viscosity, etc. of the fuel oil.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN208442827U discloses a burner with a fuel oil monitoring and control system, which includes a burner body and a fuel oil monitoring and control system. The fuel oil monitoring and control system includes an oil pump, a heater, a temperature detector, an oil quality sensor, a flow meter, an atomization gas volume adjustment device, an atomization gas pressure detector and a controller.
