Detailed description of the invention
Below, in greater detail with reference to the attached drawings the present invention is described.
With reference to figure 2, burner 200 of the present invention comprises combustion section 100, memory 201 and control part 210.In the burner 200 of Fig. 2, eliminate explanation the present invention and non-vital inscape, obviously can also have user interface etc.
The combustion section of other structures beyond the structure that combustion section 100 also can adopt Fig. 1 to pass the imperial examinations at the provincial level to exemplify, but as long as can application of air ratio control mode carried out the quantity of heat given up of control combustion device 200 entirety by the revolution controlling blower fan 10.
Memory 201 stores burning table, and this burning table record presses the benchmark blast (Ref.APS) of quantity of heat given up and benchmark revolution (Ref.RPM) information for output reference blast (Ref.APS).As previously mentioned, carried out the quantity of heat given up of control combustion device 200 by the flow velocity (that is, utilizing the blast that wind pressure sensor 23 measures) of air according to AIR Proportional control mode.Wherein, benchmark blast is the blast corresponding to the air velocity for generation of corresponding quantity of heat given up, and benchmark revolution is the revolution in order to produce corresponding blast and presetting blower fan 10.
In addition, the highest critical revolutions (Max.RPM) by quantity of heat given up are stored in memory 201.The highest critical revolutions are peaks that benchmark revolution can be compensated in the following blower fan adjustment process that will illustrate, it is determined respectively by quantity of heat given up.
Control part 210 comprises Combustion System portion 211 and blower fan adjustment part 213, and it not only controls the integrated operation of burner 200 of the present invention, but also performs the blower fan adjustment function as feature of the present invention.
Combustion System portion 211 read from memory 201 in order to the heat exporting user and ask with in the flux matched benchmark revolution (Ref.RPM) of associated hot, and drive blower fan 10 with benchmark revolution (Ref.RPM).Certainly, according to control mode, Combustion System portion 211 can adopt the revolution gone out with the mode extra computation that counts by benchmark revolution, but the benchmark revolution that control criterion is still flux matched with associated hot.
Blower fan adjustment part 213 performs the blower fan adjustment function as feature of the present invention.The operation of blower fan adjustment part 213 is described with reference to Fig. 3.
Blower fan adjustment function of the present invention is used for addressing the problem: although drive blower fan 10 to can not get corresponding benchmark blast with presetting benchmark revolution, result cannot export desired heat.As previously mentioned, the flow velocity of air because of setting place (moistening region and dry region), rational height, flue length, flue blocking whether or season etc. and different between burner, even and if same burner is not remained constant yet and can change, compensate with therefore utilizing described functional cycle and continue amendment benchmark revolution.Combustion System portion 211 also inoperation in the process that blower fan adjustment function performs.
< blower fan adjustment modes; S301>
With reference to figure 3, blower fan adjustment part 213 judges whether to enter into presetting blower fan adjustment modes.If enter into blower fan adjustment modes, then perform follow-up blower fan set-up procedure.The judgement whether blower fan adjustment modes enters can only perform when arranging burner 200 at first, but also periodically can perform according to embodiment, such as, can perform for the cycle with 30 days thus compensate the change of external environment.
< blower fan adjustment first step; S303, S305>
When corresponding to blower fan adjustment modes, blower fan adjustment part 213 first closing gas valve door 21 and cut off and flow into the gas supply of blower fan 10, and multiple valve 15 is all opened.Multiple valve 15 is fully opened, and implements secondary and opens, enforcement three grades unlatching for three grades of valves for secondary valve.But, not must apply multiple valve 15 in combustion section 100 of the present invention, also can apply one-level valve according to embodiment and replace multiple valve 15.Accordingly, be fed to no longer being mixing air and being only air of blower fan 10, and the transfer capability (S303) of the blower fan 10 that the revolution based on blower fan adjustment part 213 controls can be checked.
Blower fan adjustment part 213 drives blower fan 10 with one of benchmark revolution (Ref.RPM) being stored in memory 201, and reads blast (Act.APS) (S305) measured by wind pressure sensor 23.
< blower fan adjustment second step; S307 to S321>
Blower fan adjustment part 213 judges the blast (Act.APS) whether same or similar with benchmark blast (Ref.APS) (S307) measured in step S305, if measuring blast (Act.APS) is within critical range with the difference of benchmark blast (Ref.APS), be then judged as normal condition (S309).
If the judged result of step S307, measure blast (Act.APS) and exceed critical range with the difference of benchmark blast (Ref.APS), then mean the environment such as the situation of flue, season become from set current benchmark revolution when different.Therefore, blower fan adjustment part 213 continues to change the revolution for driving blower fan 10, to make the measurement blast (Act.APS) consistent in critical range with benchmark blast (Ref.APS) (S311, S313) read from wind pressure sensor 23.
Then, if it is consistent in critical range with the difference of benchmark blast (Ref.APS) to measure blast (Act.APS), the offset (current revolution) be then considered as benchmark revolution (Ref.RPM) is determined, 213, blower fan adjustment part judges whether " the revolution rate of change " based on correcting is the value being greater than " heat corrects critical corrected rate ".Wherein, " revolution rate of change " represents the ratio of corrected value (the current revolution determined in step S313) and benchmark revolution, such as, if benchmark revolution is 100 and corrected value (current revolution) is 120, then revolution rate of change will be 120%." heat corrects critical corrected rate " is correction in order to only carry out exceeding preset range and the critical value adopted, and it is restricted to the minimum of a value of the revolution rate of change will applying correction.Such as, when " heat corrects critical corrected rate " is 103%, if revolution rate of change is less than 103%, corrects with regard to not application of heat and stop (S315).
If the judged result of step S315, revolution rate of change is that heat corrects more than critical corrected rate, then think and need to correct benchmark revolution, and the benchmark revolution be stored in memory 201 is corrected to current revolution, thus complete the correction (S317) of blower fan.
If the judged result of step S315, revolution rate of change is less than heat and corrects critical corrected rate, then think without the need to correcting benchmark revolution, and maintains the benchmark revolution (Ref.RPM) that is stored in memory 201 and do not perform correction.
And, in the process that step S311 and S313 performs, even if if also do not make measurement blast again consistent in critical range with the difference of benchmark blast under the state of the highest critical revolutions (Max.RPM) of application correlation output heat, then blower fan adjustment part 213 is judged to correct benchmark revolution.Therefore, the highest critical revolutions (Max.RPM) of burner 200 are applied as the revolution for controlling corresponding heat by blower fan adjustment part 213, and change benchmark revolution (Ref.RPM) (S319) in memory 201.
The heat bearing calibration of burner of the present invention is performed by above method.The blower fan method of adjustment of Combustion System portion 211 in order to the heat exporting user and ask according to Fig. 3 and again control blower fan 10 with the benchmark revolution stored.So even if cause the changed condition such as flue blocks gradually because of seasonal law or use, burner 200 also still can export the heat that user asks.
< embodiment >
According to embodiment, the blower fan bearing calibration shown in Fig. 3 can will be mapped in the highest benchmark blast (Max.Ref.APS) of the highest quantity of heat given up of burner 200 as benchmark.Accordingly, can readjust by benchmark blast corresponding to each quantity of heat given up in proportional mode based on the highest benchmark blast corrected.
Above; illustrate and the preferred embodiments of the present invention are described; but the present invention is not limited to described specific embodiment; the personnel in the technical field belonging to the present invention with general knowledge certainly can realize various distortion and implement when not departing from claims the purport of the present invention of asking to protect, should not stand in outside technological thought of the present invention or prospect scope and treat those distortion enforcement isolatedly.
