Burning control system of fuel oil burner

Abstract

The invention discloses a burning control system of a fuel oil burner, which comprises an oil transportation passage, an atomizing medium passage, an ignition device, a blower device, an air quantity adjusting device and an oil quantity adjusting device. The burning control system of the fuel oil burner additionally comprises a controller. The controller controls the operation of the blower device, an igniter and an atomizer. The air quantity adjusting device comprises a fan and a fan driver. A fan driver feedback device is arranged on the fan driver. An air pressure sensor is arranged in the ignition device. The air pressure sensor outputs an air pressure signal to the controller. The controller controls the operation of the fan driver according to the feedback signal of the fan driver and the air pressure signal. The fan driver changes the output air quantity of the fan by changing the working frequency of the fan. A flame signal sensor is additionally arranged in the ignition device and outputs a flame signal to the controller. The burning control system of the fuel oil burner can automatically adjust the air quantity and the oil quantity according to preset air-to-oil ratio and can overcome the defect of wear or deformation caused by long-term operation of the traditional burner which adopts a mechanical connecting rod.

Description

technical field [0001] The invention relates to the technical field of combustion adjustment and control, in particular to a combustion control system of an oil burner capable of realizing energy-saving and environment-friendly heating. Background technique [0002] The current conventional automatic control burners can be divided into single-stage fire, two-stage fire, and proportional adjustment. They are all mechanically linked, and the amount of fire is adjusted by changing the stroke of the actuator, and then driving the damper and the fuel regulating valve through the linkage. For example, the automatic control burner produced by a certain company in the prior art controls the operation of the electric actuator (servo motor) through the temperature control system, and then drives the damper and the fuel regulating valve to operate by the connecting rod to adjust the size of the fire. The action of each valve is controlled by a solidified program controller, and the ad...

AI Technical Summary

Problems solved by technology

[0003] (1) High energy consumption: low accuracy of mechanical adjustment of oil-gas ratio, insufficient combustion, high pressure requirements of oil pump;

[0004] (2) Complicated operation: due to the different calorific value of different fuels, the air-oil ratio needs to be readjusted;

[0005] (3) The fuel adjustment ratio of the burner is low: 1:2.5

[0006] (4) In addition, the combustion system in the prior art also has problems such as complex mechanical structure, short service life of parts, and high cost
