[0001]

TECHNICAL FIELD The present invention relates to a system for remotely monitoring the combustion state of a burner installed in an industrial furnace.

[0002]

Various types of industrial furnaces are utilized in various industries. These industrial furnaces are provided with burners that burn a fuel to generate a flame as a heat source.
In managing the combustion state of these burners, generally, the person who uses the burner makes appropriate judgments according to a predetermined simple index. As a determination method, for example, there is a method of confirming the amount of fuel and air used for combustion with a meter and confirming whether or not the fuel is being used at a normal rate. There is also a method of measuring the flame current value using a flame rod or flame eye measuring instrument and determining the combustion state from the measured value.

[0003]

[Problems to be Solved] However, the conventional method of managing the combustion state is not always sufficient. That is, as described above, the user of the burner normally confirms the combustion state of the burner, but the user does not necessarily have sufficient knowledge of the combustion state of the burner, and in some cases the optimum judgment cannot be made. Further, the combustion state of the burner can be judged relatively accurately in the state of the flame, but it is often difficult for a user who does not have sufficient knowledge to make an accurate judgment, and it is also difficult to constantly monitor it. In many cases.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a remote monitoring system for an industrial furnace burner capable of accurately determining the combustion state of the burner at a remote location.

In the present invention, the burner side computer has the moving picture transmitting means, and the monitoring computer has the moving picture displaying means. And
The burner side computer and the monitoring computer are connected via the broadband line.
Therefore, the moving image data sent from the burner side computer is transmitted at a very high speed by the moving image transmitting means, and can be displayed as a clear image by the moving image display means in almost real time.

At the installation location of the monitoring computer, it is possible to visually grasp the color and shape of the flame of the burner at a remote location. Therefore, for a supervisor who has sufficient knowledge to determine the combustion state from the flame state, the combustion state of the burner can be easily and accurately determined almost in real time based on the information obtained from the moving image display means. it can. Therefore, even if the burner user does not notice the deterioration of the combustion state, it is possible to detect it early in a remote place where the above-mentioned monitoring computer is installed, and take an early countermeasure.

As described above, according to the present invention, it is possible to provide a remote monitoring system for an industrial furnace burner capable of accurately determining the combustion state of the burner at a remote location.

[0009]

In this case, the state of flame can be grasped not only visually from the image but also from the auditory point of view by the combustion sound linked to the moving image. As a result, the accuracy of determining the combustion state can be further improved. Further, in this case, it is of course possible to integrate the voice transmitting means and the moving image transmitting means into one transmitting means.

Examples of the combustion data include the flow rate of fuel, the flow rate of mixed air, the flame current value calculated using a flame rod or flame eye, the temperature in the furnace, and the component data (NOx, CO) of the gas discharged from the furnace. , CO ₂ , O _2, etc.), etc., and one or more of these can be used.

Further, the monitoring computer has abnormality determining means for periodically or irregularly obtaining the emission spectrum of the flame from the moving image data and determining whether the combustion state is normal or not based on the emission spectrum. It is preferable to have (Claim 4). The emission spectrum of the flame is the intensity of the light emitted from the flame for each frequency. Then, by utilizing this emission spectrum, it is possible to make a very advanced judgment of the combustion state. Therefore, as described above, in the monitoring computer, the abnormality determination means utilizing the emission spectrum obtained from the moving image data can make accurate abnormality determination. As a specific determination method, for example, the range of the intensity of the emission spectrum of the flame during normal combustion is stored, and the emission spectrum obtained periodically or aperiodically is stored in this range.

There are the above-mentioned voice data or various combustion data such as fuel consumption. Then, these data are managed as a data group associated with the password. Then, as described above, by collating the password transmitted from the client computer, it is possible to inquire each of the above data individually. By adopting such a system, the client computer can independently analyze the combustion state and the amount of fuel used without directly operating the monitoring computer. As a result, the burner combustion management can be made easier than before, and highly accurate combustion control can be performed, and it is possible to prevent wasteful use of fuel and save energy. Also, since a broadband line is used, smooth transmission / reception is possible even when the data sent to the client computer includes moving image data.
