Abstract

The invention relates to an automatic control device of an infrared ray burner, which is characterized by comprising an infrared ray sensor, a singlechip, a variable-frequency governor, a variable-frequency speed regulating fan, a step motor and an air door, wherein the signal output end of the infrared ray sensor is connected with one end of the singlechip, one output end of the singlechip is connected with the variable-frequency speed regulating fan through the variable-frequency governor, the other output end of the singlechip is connected with the step motor, and the step motor drives the air door. The invention has the advantages of controlling the rotating speed of the fan or the opening of the air inlet air door by using the strength of infrared rays generated by infrared ray burning, maintaining the stability of the infrared ray burning, achieving the best energy-saving effect of the burner, saving great cost of manual adjustment, and bringing convenience for a user due to no need of maintenance.

Description

technical field [0001] The invention relates to an automatic control device for an infrared burner, which is mainly used in a combustion control system of a condensing wall-hung boiler to improve the combustion stability of the burner, and improve the thermal efficiency and use comfort of the wall-hung boiler. Background technique [0002] An existing condensing wall-hung boiler uses a negative pressure infrared combustion method to convert gas and heat energy, and this technology is very difficult. Since infrared burning ceramic plates are very sensitive to gas, air mixing ratio, gas pressure, atmospheric pressure, ambient temperature, etc., it is difficult to ensure the normal combustion of ceramic plates. There is not a relatively mature experience in the world that can be used for reference, especially in negative pressure combustion, and the stability needs to be improved. Experiments have shown that the mixing ratio of gas and air is the main factor affecting the comb...
