Combustion control system of an oil burner

Abstract

The invention discloses a combustion control system of a fuel oil burner, which comprises an oil delivery channel, an atomization medium channel, an ignition device, an air volume adjustment device, an oil volume adjustment device and a controller; the oil delivery port of the oil delivery channel is provided with an oil delivery pump , there is an oil pressure sensor in the oil delivery channel, and the oil volume adjustment device is the oil inlet valve; the ignition device includes an igniter and an atomizer; the ignition device is equipped with a flame signal sensor, a wind pressure sensor, and an atomization medium pressure sensor; The adjustment device includes a damper and a damper driver; the damper driver is provided with a damper position sensor; the controller controls the fuel pump, blower device, igniter, atomizer, heater, the start of the damper driver and the opening or closing of the oil inlet valve; The controller receives the output signals of each sensor, and controls the oil intake, the oil pressure in the oil delivery channel, the position of the damper and the air pressure according to the relevant signals. The invention can realize the independent adjustment of oil volume and air volume, has low energy consumption and high system reliability.

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 the damper and the fuel regulating valve are driven by the linkage to adjust the size of the fire. The action of each valve is controlled by a solidified program controller, and the adjustability is...

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] 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.
