Gas burner

Abstract

The invention discloses a gas burner, which comprises a burning head, a controller, a man-machine interaction device, an ignition device, a flame monitoring device, a fuel device and an air supply device, wherein the ignition device and the flame monitoring device are mounted on the burning head, and the fuel device and the air supply device are respectively connected with the controller. The air supply device comprises a blower device, an air pressure detecting device and a fan driver, the blower device corresponds to an air inlet pipe of the burning head, the air pressure detecting device and the fan driver are mounted on the air inlet pipe of the burning head, the fan driver is used for changing the air outlet volume of the blower device by changing the frequency of the blower device, a fan driver feedback device is arranged on the fan driver, and the air pressure detecting device, the fan driver feedback device, the fan driver and the blower device are respectively connected with the controller. The gas volume and the air volume are individually and automatically adjusted, an air-gas ratio is preset by the aid of the man-machine interaction device, and energy consumption is low, so that emission of waste gas is reduced. By the aid of the man-machine interaction device, the problem of complicated operation is solved, and the gas burner is high in automation degree, accurate in temperature control and high in gas adjusting ratio.

Description

technical field [0001] The invention relates to a burner, in particular to a gas burner. Background technique [0002] At present, conventional gas burners can be divided into single-stage fire, two-stage fire, and proportional adjustment, but they are all mechanically linked. They are adjusted by changing the stroke of the servo motor, and then driving the damper and the gas disc valve through the linkage. The size of the amount of fire. After long-term operation of this gas burner, the connecting rod will be worn or deformed, so the following defects generally exist: (1) high energy consumption (low precision of mechanical adjustment of air-gas ratio, insufficient combustion); (2) operation Complicated (gas pressure changes need to be readjusted); (3) The gas adjustment ratio of the burner is low (1:4); (4) The mechanical structure is complicated, the service life of the parts is short, and the economy is poor. Contents of the invention [0003] In view of the deficien...
