The embodiment of the present invention provides a kind of method for adjusting burner air-fuel ratio, applied to the bringing-up section of annealing furnace, annealing furnace Bringing-up section include several heating regions, a heating region may include one or more burners.
It is shown in Figure 1, the method for the adjusting burner air-fuel ratio of the embodiment of the present invention, comprising:
Step 101: target heating region is determined from the bringing-up section of annealing furnace.
Specifically, in a step 101, it can arbitrarily be selected from several heating regions that the bringing-up section of annealing furnace includes One heating region is as target heating region, for example, if the bringing-up section of annealing furnace includes the first heating region, the second heating zone Domain and third heating region, then can be using the second heating region as target heating region.Target heating region may include one A or multiple burners.
Step 102: the heating power of the burner of target heating region being adjusted to multiple and different targets respectively and heats function Rate, and corresponding target burner remaining oxygen is obtained under each target heating power respectively.

Step 103: based on the corresponding relationship between target heating power and target burner remaining oxygen, establishing air-fuel ratio debugging Curve.
Specifically, air-fuel ratio debugging curve is used to characterize the corresponding relationship between heating power and burner remaining oxygen, empty Combustion is specifically as follows than debugging curve: in the coordinate system established using heating power and burner remaining oxygen as two reference axis Under the curve drawn out.In embodiments of the present invention, the tune to burner air-fuel ratio is realized by the adjusting to burner remaining oxygen Section, meanwhile, in embodiments of the present invention, the adjusting of burner remaining oxygen is realized by adjusting combustion air pressure difference, therefore, It in a specific embodiment, in step 103, can be based on pair between target heating power and target burner remaining oxygen It should be related to and the corresponding relationship between burner remaining oxygen and combustion air pressure difference, foundation are residual comprising combustion air pressure difference, burner The air-fuel ratio of corresponding relationship debugs curve between oxygen amount and heating power, wherein between burner remaining oxygen and combustion air pressure difference With intrinsic proportionate relationship, thus, air-fuel ratio debugging curve is specifically as follows: with heating power, burner remaining oxygen, combustion-supporting The curve drawn out under the coordinate system that air pressure difference is established respectively as three reference axis, as shown in Figure 3.For example, being based on first Corresponding relationship between heating power and first object burner remaining oxygen draws out first point under coordinate system, is based on second Corresponding relationship between heating power and the second target burner remaining oxygen, draws out second point under coordinate system, is based on third Corresponding relationship between heating power and third target burner remaining oxygen, draws out third point under coordinate system, by above-mentioned One point, second point and third point carry out line, so that acquisition is right between heating power and burner remaining oxygen for characterizing The first curve that should be related to;Meanwhile it being burnt obtaining first object burner remaining oxygen, the second target burner remaining oxygen and third target After mouth remaining oxygen, according to proportionate relationship intrinsic between burner remaining oxygen and combustion air pressure difference, the first combustion air is obtained Pressure difference, the second combustion air pressure difference and third combustion air pressure difference, according to first object burner remaining oxygen and the first combustion air Corresponding relationship between pressure difference draws out first point under coordinate system, combustion-supporting according to the second target burner remaining oxygen and second Corresponding relationship between air pressure difference draws out second point under coordinate system, according to third target burner remaining oxygen and third Corresponding relationship between combustion air pressure difference draws out third point under coordinate system, by above-mentioned first point, second point and Third point carries out line, to obtain the second song for characterizing corresponding relationship between burner remaining oxygen and combustion air pressure difference Line, the first curve and the second curve constitute air-fuel ratio and debug curve, as shown in Figure 2.It should be noted that the point drawn is more, The curve that then final line obtains is more smooth.
Step 104: burner region to be debugged is determined from bringing-up section.
Specifically, burner region to be debugged is located in bringing-up section, and usual burner region to be debugged is single with heating region Position, that is, a burner region to be debugged is a heating region, thus, step 104 can be that one is determined from bringing-up section A heating region is burner region to be debugged, and burner region to be debugged is the region different from target heating region.
Step 105: determining the heating power to be debugged of the burner in burner region to be debugged.
Specifically, heating power to be debugged is directed to one or more burners in burner region to be debugged.Wait adjust Examination heating power obtains according to the following formula:
α≤Pi-hold≤min(100,n*Ptotal-old)
Wherein, α is minimum heating power, Pi-holdFor heating power to be debugged, n is the sum of the heating region of bringing-up section,The range of α is the 5~15% of maximum heating power.For example, if the bringing-up section of annealing furnace includes 7 heating Region, the corresponding heating power of each heating region is respectively 20%, 30%, 40%, 40%, 50%, 60% and 70%, minimum plus Thermal power is 5%, thus, Ptotal-old=(20%+30%+40%+40%+50%+60%+70%)/7=44.29%, 5≤ Pi-hold≤ min (100,7*44.49), it is final to obtain: 5≤Pi-hold≤ 100, Pi-holdIt can arbitrarily be selected from 5% and 100% It takes, such as chooses 50% and be used as heating power to be debugged.The heating power to be debugged obtained using above-mentioned formula is to burner to be debugged The air-fuel ratio of the burner in region be adjusted can guarantee adjust after air-fuel ratio it is moderate, can not only guarantee the heating energy of burner Power, additionally it is possible to avoid the generation of second-time burning.
