Abstract

The invention relates to the technical field of annealing processes, in particular to a method and device for adjusting an air-fuel ratio of burners. The method includes the steps that a target heating zone is determined from a heating section of an annealing furnace; the heating power of the burners in the target heating zone is correspondingly adjusted to different target heating power; the corresponding target burner residual oxygen amount is obtained under the different target heating power; an air-fuel ratio debugging curve is established based on a correspondence between the target heating power and the target burner residual oxygen amount; burner areas to be debugged are determined from the heating section; the to-be-debugged heating power of the burners in the burner areas to be debugged is determined; the to-be-debugged burner residual oxygen amount corresponding to the to-be-debugged heating power is determined based on the air-fuel ratio debugging curve; and the air-fuel ratio of the burners in the burner areas to be debugged is adjusted based on the to-be-debugged burner residual oxygen amount.

Description

technical field [0001] The invention relates to the technical field of annealing technology, in particular to a method and a device for adjusting the air-fuel ratio of a burner. Background technique [0002] The vertical annealing furnace is mainly used for annealing treatment of hard-rolled coils, so that the hard-rolled coils can achieve satisfactory mechanical properties for subsequent deep processing. Among them, the annealing treatment includes heating, soaking, cooling, overaging and water quenching treatment. The heating section usually uses thermal radiation to heat the strip steel. After the "radiant tube" is mixed and ignited by the ignition electrode, the strip steel is heated by thermal radiation. Among them, the mixing ratio of air and gas, that is, the "air-fuel ratio", directly affects the radiation efficiency. [0003] For the air-fuel ratio, when the air-fuel ratio is too high, it will directly cause a large amount of unburned oxygen to take away the heat g...
