Description
Technical Field
The present invention relates to a combustion control technique for controlling combustion based on the presence or absence of a flame detected based on a sensor output of a flame sensor.
Background
In a combustion apparatus used for an industrial furnace, a boiler, a cooling and heating apparatus, a kitchen appliance, a heat exchanger, and the like, a flame sensor is provided which detects the amount of light of flame in a burner and outputs the light as an electric signal, the presence or absence of flame in a combustion control apparatus is detected based on the sensor output of the flame sensor, and combustion is controlled based on the detection result.
Conventionally, in such a combustion control device, in order to suppress the influence of output fluctuation of a flame sensor due to fluctuation of flame, extinction of flame is detected at a misfire detection level lower than an ignition detection level that is a sensor output at the time of ignition detection, that is, the presence or absence of flame is detected based on a hysteresis characteristic (for example, see patent document 1).

Disclosure of Invention
[ problems to be solved by the invention ]
However, in such a conventional technique, since the presence or absence of a flame is detected by comparing the sensor output of the flame sensor with a threshold value, the following cases are conceivable: in an environment where there is a pseudo flame with a light amount equal to or higher than the misfire detection level and equal to or lower than the ignition detection level due to the influence of disturbance light such as external light or stray light, the sensor output of the flame sensor does not decrease to the misfire detection level even if the flame is extinguished after ignition. Therefore, in this case, since flame-out due to flame-out cannot be detected, there is a possibility that fuel will continue to be discharged even after flame-out, becoming a very dangerous state.
In order to suppress the influence of such disturbance, a technique has been proposed in which the burner structure is designed to prevent disturbance light from entering the flame sensor (see, for example, patent document 2). However, what kind of countermeasure is taken depends on the equipment manufacturer, and it is difficult to say that such a countermeasure is reliably taken in all combustion apparatuses. In order to apply such a burner structure, it is necessary to change the existing combustion equipment such as replacing the existing burner, and the countermeasure cost is significantly increased.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a combustion control technique capable of safely controlling a combustion device with respect to disturbance light without changing an existing combustion device.
[ means for solving problems ]
In order to achieve the above object, a combustion control device according to the present invention is a combustion control device for controlling combustion in a combustion equipment based on the presence or absence of a combustion flame in the combustion equipment detected from a sensor output of a flame sensor, including: a combustion flame detection unit that detects the presence or absence of a combustion flame in the combustion equipment, based on a sensor output acquired from the flame sensor during combustion in the combustion equipment and a preset combustion flame threshold value; a pseudo-flame detection unit that detects a definite pseudo-flame based on the sensor output and a pseudo-flame threshold that is lower than the combustion flame threshold and that is set in advance; and a combustion control unit that controls combustion in the combustion equipment based on a combustion flame detection result obtained by the combustion flame detection unit, wherein the combustion control unit monitors a pseudo flame detection result of the pseudo flame detection unit before attempted ignition in the combustion equipment, and cancels the attempted ignition in the combustion equipment when the pseudo flame detection result continuously indicates that a pseudo flame is present within a first monitoring time.
In the combustion control device according to the present invention, the combustion flame threshold value is composed of a first combustion flame threshold value and a second combustion flame threshold value lower than the first combustion flame threshold value, and the combustion flame detection unit detects the presence of a combustion flame in the combustion device when a sensor output of the flame sensor is equal to or greater than the first combustion flame threshold value, and detects the absence of a combustion flame when the sensor output is equal to or less than the second combustion flame threshold value.
In one configuration example of the combustion control device according to the present invention, the pseudo-flame threshold value is composed of a first pseudo-flame threshold value and a second pseudo-flame threshold value lower than the first pseudo-flame threshold value, and the pseudo-flame detection unit detects that a pseudo flame due to disturbance light is present when a sensor output of the flame sensor is equal to or higher than the first pseudo-flame threshold value, and detects that a flame is clearly pseudo when the sensor output is equal to or lower than the second pseudo-flame threshold value.
In the combustion control device according to the present invention, in a configuration example, the combustion control unit starts the trial ignition in the combustion equipment when the pseudo flame detection result indicates no pseudo flame for a second monitoring time period before the trial ignition.
Further, a combustion control method according to the present invention is a combustion control method for controlling combustion in a combustion apparatus based on presence or absence of a combustion flame in the combustion apparatus detected from a sensor output of a flame sensor, including: a combustion flame detection step in which a combustion flame detection unit detects the presence or absence of a combustion flame in the combustion device based on a sensor output acquired from the flame sensor during combustion in the combustion device and a preset combustion flame threshold value; a pseudo-flame detection step in which a pseudo-flame detection unit detects a definite pseudo-flame based on the sensor output and a pseudo-flame threshold value lower than the combustion flame threshold value set in advance; and a combustion control step in which a combustion control unit controls combustion in the combustion device based on a combustion flame detection result obtained in the combustion flame detection step, wherein a suspected flame detection result of the suspected flame detection step is monitored before attempted ignition in the combustion device, and the attempted ignition in the combustion device is cancelled when the suspected flame detection result continuously indicates that a suspected flame is present within a first monitoring time.
[ Effect of the invention ]
According to the present invention, when the pseudo flame detection result from the pseudo flame detection unit continues for the first monitoring time period although combustion in the burner has not started before ignition is attempted, such disturbance light is stably detected, and even if combustion in the burner is started, there is a possibility that the combustion flame cannot be accurately detected, so that ignition attempt in the combustion device is cancelled. Thus, the combustion apparatus can be safely controlled with respect to the disturbance light. Further, since a suspected flame due to disturbance light is detected on the combustion control device side, there is no need to change the burner structure to avoid disturbance light from entering the flame sensor. Thus, since a change to the existing combustion equipment such as replacement of the existing combustor is not required, a significant increase in the countermeasure cost can be suppressed.

Detailed Description
Next, an embodiment of the present invention will be described with reference to the drawings.
[ Combustion control device ]
First, a combustion control device 10 according to an embodiment of the present invention will be described with reference to fig. 1. Fig. 1 is a block diagram showing the configuration of a combustion control device.
The combustion control device 10 is a device that performs combustion control of the combustion equipment 30 based on the sensor output S from the flame sensor 20.
The combustion equipment 30 is a general combustion equipment used for an industrial furnace, a boiler, a cooling and heating equipment, a kitchen appliance, a heat exchanger, and the like, and has a function of generating thermal energy by burning fuel in a burner.
The flame sensor 20 is a sensor that detects the light amount of flame in the burner of the combustion device 30, electrically converts the light amount, and outputs the converted light amount as a sensor output S to the combustion control apparatus 10.
The combustion control device 10 is provided with a combustion flame detection unit 11, a pseudo flame detection unit 12, and a combustion control unit 13 as main functional units. These functional units may be constituted by a control circuit using an IC, or may be realized by cooperating a CPU and a program.
The combustion flame detection unit 11 has a function of detecting the presence or absence of a combustion flame in the combustion device 30 based on the sensor output S from the flame sensor 20 and a preset combustion flame threshold value. In the case where there is a hysteresis characteristic in the detection of the combustion flame, a first combustion flame threshold H1 (ignition detection level) and a second combustion flame threshold H2 (misfire detection level) lower than the first combustion flame threshold H1 are used as the combustion flame thresholds.
Fig. 2 is an explanatory diagram illustrating a combustion flame detection operation. When the sensor output S of the flame sensor 20 is equal to or higher than the first combustion flame threshold H1 (ignition detection level), the combustion flame detector 11 detects the presence of the combustion flame Bon in the combustion device 30, and when the sensor output S is equal to or lower than the second combustion flame threshold H2 (flame-out detection level) which is lower than the first combustion flame threshold H1, the combustion flame detector 11 detects the absence of the combustion flame Boff.
The pseudo-flame detection unit 12 has a function of detecting the presence of a pseudo-flame due to disturbance light based on the sensor output S from the flame sensor 20 and a pre-set pseudo-flame threshold value. The pseudo flame is a pseudo flame in which the level of the sensor output S is increased by the influence of disturbance light such as external light or stray light, and is not a combustion flame indicating actual combustion in the combustion device 30. In the case of a hysteresis characteristic in the detection of a suspected flame, a first suspected flame threshold H3 (at a suspected flame detection level) and a second suspected flame threshold H4 (at an undoubted flame detection level) lower than the first suspected flame threshold H3 are used as suspected flame thresholds.
Fig. 3 is an explanatory diagram illustrating a pseudo flame detection operation. The pseudo flame detection unit 12 detects the pseudo flame Pon due to disturbance light when the sensor output S of the flame sensor 20 becomes equal to or higher than the pseudo flame threshold H3 (at a pseudo flame detection level), and detects the absence of the pseudo flame Poff when the sensor output S becomes equal to or lower than the pseudo flame threshold H4 (at a pseudo flame detection level of no doubt). At this time, by setting the pseudo-flame thresholds H3, H4 to values lower than the second combustion flame threshold H2, the presence of a definite pseudo-flame can be detected more strictly. The pseudo flame thresholds H3 and H4 may be appropriately changed. Although stable detection can be achieved due to the presence of the hysteresis characteristic in the detection of the pseudo flame, the present invention is not necessarily configured, and the pseudo flame thresholds H3 and H4 may be set to the same value when the pseudo flame does not have the hysteresis characteristic.
The combustion control section 13 has a function of controlling combustion in the combustion apparatus 30 based on the combustion flame result B from the combustion flame detection section 11 in the combustion of the combustion apparatus 30. In the combustion control here, as in the conventional case, for example, when the combustion flame detection result B indicates the presence of the combustion flame Bon, the control signal C instructing the supply of fuel to the combustor is output to the combustion device 30, and when the fuel flame detection result B indicates the absence of the combustion flame Boff, the control signal C instructing the stop of the supply of fuel to the combustor is output to the combustion device 30.
Further, the combustion control unit 13 includes: a function of monitoring the pseudo flame detection result P from the pseudo flame detection unit 12 before the attempted ignition of the combustion device 30 and canceling the attempted ignition of the combustion device 30 when the pseudo flame detection result P indicates the presence of the pseudo flame continuously for a preset first monitoring time T1; and a function of starting the ignition attempt in the combustion apparatus 30 in a case where the suspected flame detection result P indicates no suspected flame for a second monitoring time set in advance before the ignition attempt.
In addition, as for the operation in the case where the pseudo flame detection result P indicates the presence of the pseudo flame, the operation of the combustion device 30 can be completely stopped by continuously locking the combustion device 30 for a certain period of time. When the pseudo flame detection result P indicates the presence of a pseudo flame, the lock may be immediately performed, or the lock may be left on for a certain period of time without being performed.
[ operation of the present embodiment ]
Next, the operation of the combustion control device 10 according to the embodiment of the present invention will be described with reference to fig. 4. Fig. 4 is a flowchart showing a tentative ignition propriety determination process.
The combustion control portion 13 executes the tentative ignition propriety determination process of fig. 4 before starting the tentative ignition in the combustion apparatus 30.
First, the combustion control unit 13 acquires a pseudo-flame detection result P from the pseudo-flame detection unit 12 (step 100). Here, when the sensor output S of the flame sensor 20 is equal to or less than the pseudo-flame threshold H4 and the pseudo-flame detection result P indicates that the flame Poff is clearly perceived (no in step 101), the combustion control unit 13 starts the trial ignition in the combustion apparatus 30 (step 102) and ends a series of trial ignition propriety determination processing. After that, the combustion control portion 13 starts the combustion control of the combustion apparatus 30 based on the combustion flame detection result B from the combustion flame detection portion 11.
On the other hand, when the sensor output S of the flame sensor 20 is equal to or higher than the pseudo-flame threshold H3 and the pseudo-flame detection result P indicates the presence of the pseudo-flame Pon (yes in step 101), the combustion control unit 13 starts monitoring of the pseudo-flame detection result P thereafter (step 103).
Here, when the sensor output S of the flame sensor 20 is maintained at or above the pseudo-flame threshold H3 and indicates that the pseudo-flame detection result P continuously indicates the presence of the pseudo-flame Pon within the first monitoring time (yes in step 104), the flame sensor 20 may stably detect disturbance light and the combustion flame may not be correctly detected, and therefore the combustion control unit 13 cancels the tentative ignition in the combustion device 30 (step 105) and ends the series of tentative ignition possibility determination processing. At this time, as a specific example of canceling the trial ignition, the operation of the combustion apparatus 30 may be stopped, that is, locked. Thereby, high safety can be obtained.
Further, when the pseudo flame detection result P does not indicate the presence of the pseudo flame Pon continuously for the first monitoring time (no in step 104) and the pseudo flame detection result P indicates the absence of the pseudo flame Poff continuously for the second monitoring time (yes in step 106), the flame sensor 20 does not detect the disturbance light and the combustion flame can be detected accurately, and therefore the combustion control unit 13 proceeds to step 102 to start the ignition attempt in the combustion device 30.
If the pseudo flame Pon does not continue for the first monitoring time and no pseudo flame Poff does not continue for the second monitoring time (no in step 106), the combustion control unit 13 returns to step 103 and continues to monitor the pseudo flame detection result P.
The first monitoring time and the second monitoring time may be set in advance according to the combustion equipment 30 to be controlled, or the same time may be set for both.
[ Effect of the embodiment of the invention ]
As described above, in the embodiment of the present invention, when the sensor output S of the flame sensor 20 becomes equal to or greater than the pseudo-flame threshold H3, the pseudo-flame detection unit 12 detects the pseudo-flame Pon due to disturbance light, when the sensor output S becomes equal to or less than the pseudo-flame threshold H4, the pseudo-flame detection unit 12 detects no pseudo-flame Poff, the combustion control unit 13 monitors the pseudo-flame detection result P from the pseudo-flame detection unit 12 before the attempted ignition of the combustion device 30, and when the pseudo-flame detection result P continuously indicates the presence of the pseudo-flame within the first monitoring time, the attempted ignition of the combustion device 30 is cancelled.
Thus, when the pseudo flame detection result from the pseudo flame detection unit 12 continues for the first monitoring time period although combustion in the burner has not started before ignition is attempted, such disturbance light is stably detected, and even if combustion in the burner is started, there is a possibility that the combustion flame cannot be accurately detected, so that ignition attempt in the combustion device 30 is cancelled. Therefore, the combustion apparatus 30 can be safely controlled with respect to the disturbance light. Further, since the presence or absence of a suspected flame due to disturbance light is detected on the combustion control device 10 side, it is not necessary to change the burner structure to avoid the disturbance light from entering the flame sensor 20. This eliminates the need for changing the existing combustion equipment 30, such as replacing the existing burner, and thus can prevent a significant increase in the cost of countermeasures.
