The combustion information generator 33 acquires measurement information from various measurement units provided in the combustion facility 10 from the terminal device 20 . Then, the combustion information creating unit 33 creates specific information of the combustion equipment 10 based on the measurement information. In this embodiment, the specific information is information related to combustion in the combustion facility 10 that is directly obtained from the measurement information.
The combustion information creating unit 33 of the present embodiment specifies the air ratio (combustion air ratio or burner air ratio), the exhaust loss, the heat possessed by the object to be heated, and the heat radiation loss as the specific information. The identification of each piece of specific information by the combustion information generator 33 will be described in detail below.

The combustion information creation unit 33 identifies the air ratio in the combustion equipment 10 . Here, the air ratio is determined by (actual air amount)/(theoretical air amount). The theoretical amount of air is the amount of air required for complete combustion of fuel. In the description of this embodiment, the air ratio of the atmosphere in the furnace chamber 11 is called the combustion air ratio, and the air ratio of the gas in which the fuel and the oxidizer are mixed in the main burner 12 is called the burner air ratio. Note that the burner air ratio and the combustion air ratio basically correspond to each other. However, depending on conditions such as the degree of airtightness of the furnace chamber 11, outside air may enter the furnace chamber 11 from the outside during combustion. In such cases, there may be a discrepancy between the burner air ratio and the combustion air ratio.

Then, the combustion information creating unit 33 specifies the combustion air ratio in the furnace chamber 11 based on the oxygen concentration [%] of the combustion exhaust gas. The combustion information creating unit 33 of the present embodiment calculates the combustion air ratio, for example, based on the formula: combustion air ratio=(21)/(21-oxygen concentration [%]).
Further, the combustion information creating unit 33 specifies the burner air ratio in the main burner 12 based on the fuel flow rate [m^3/h] and the air flow rate [m^3/h].

The combustion information creation unit 33 identifies the exhaust loss [%] of the combustion equipment 10 . The exhaust loss can be specified using the previously obtained relationship between the temperature [°C] of the combustion exhaust gas, the combustion air ratio, and the exhaust loss [%]. In this embodiment, the combustion information generator 33 can obtain the combustion air ratio as described above. Furthermore, the combustion information creating unit 33 can obtain the temperature [°C] of the combustion exhaust gas as measurement information.

Then, the combustion information creating section 33 sends the identified specific information to the combustion information storage section 34 .

"Processing information"
The combustion information creation unit 33 creates processing information for displaying the specific information arranged in chronological order. For example, the combustion information generator 33 displays specific information such as combustion air ratio, burner air ratio, and exhaust loss at predetermined time intervals (for example, hourly, monthly, etc.).

Further, for example, when the user or the like adjusts the combustion conditions related to the combustion of the combustion facility 10, the combustion information creation unit 33 displays the adjustment history showing changes in the specific information before and after the adjustment as the processing information. . For example, the combustion information creation unit 33 displays, as an adjustment history, the value before and after the adjustment of the burner air ratio by adjusting the fuel flow rate and the air flow rate in the adjustment unit 15 of the combustion equipment 10 respectively. .
Note that the fact that the combustion condition has been adjusted is specified, for example, by accepting an input of information on the presence/absence of adjustment from the user, or by making a determination based on the measurement information of the measurement unit.

Further, the combustion information creating section 33 creates processed information by aggregating the specific information and the information obtained using the specific information in a predetermined unit. The predetermined unit can be, for example, batch processing of the object to be heated, hourly, daily, monthly, yearly, or the like.
The combustion information creating unit 33 of the present embodiment displays processing information obtained by totaling the processing unit consumption for each month. Here, the basic unit of processing in this embodiment is the energy amount of the fuel required for processing the object to be heated per unit. Then, the combustion information generating unit 33 specifies the processing unit consumption [MJ/ton] based on the processing amount of the object to be heated [ton/ch] and the gas flow rate [m̂3/h].

Furthermore, the combustion information creating unit 33 identifies the degree of air intrusion into the furnace chamber 11 of the combustion equipment 10 and displays it as processing information. As described above, for example, even when the combustion equipment 10 is in a combustion state and the furnace chamber 11 is in a closed state, the outside air may enter through a gap or the like. In this case, a difference occurs between the combustion air ratio and the burner air ratio. Therefore, if the difference between the burner air ratio and the combustion air ratio is known, the combustion information generator 33 can identify the degree of outside air entering the furnace chamber 11 . The combustion information creating unit 33 of the present embodiment specifies the degree of outside air entering the furnace chamber 11 using information on the burner air ratio and the combustion air ratio obtained as the specifying information.

Further, the combustion information creation unit 33 creates a heat balance chart showing the heat balance of the combustion facility 10 as processing information. The heat balance diagram visually expresses the heat input such as the fuel's potential heat generated by the flame of the main burner 12, and the heat output such as the heated potential heat of the object to be heated and the exhaust loss. Then, the combustion information creating unit 33 of the present embodiment uses the specified information specified as described above to specify the elements that make up the heat balance in the heat balance diagram.

Further, the combustion information creating unit 33 identifies the heat loss from the opening of the furnace chamber 11 and displays it as processing information. Here, the opening can be exemplified by an opening when a door provided for taking the heated part into and out of the furnace chamber 11 is opened.

Specifically, the combustion information creating unit 33 determines whether to open the door based on the pressure drop in the furnace chamber 11 . Then, the combustion information creating unit 33 identifies the heat loss from the opening from the temperature change in the furnace chamber 11 before and after that.

"Advice Information"
The combustion information creating unit 33 presents advice information related to combustion in the combustion facility 10 to the user based on the identified specific information.

The combustion information creating unit 33 creates information regarding the adjustment of the burner air ratio as advice information. For example, a target value of the air ratio is set as an example of the target value of the combustion condition (for example, an air ratio of 1.1). This target value may be a value received in advance from the user via the terminal device 20 or a recommended value specified by the server device 30 side.
Then, the combustion information creating unit 33 compares the target value with the specified air ratio as the combustion condition, and creates advice information for achieving the air ratio as the target value. Specifically, the combustion information creating unit 33 creates advice information instructing that the actual combustion conditions become the air ratio as the target value.
Note that the target value used when the combustion information creating section 33 creates advice information is not limited to one value. For example, the combustion information creating section 33 may create advice information based on a comparison between an allowable range of positive and negative values with respect to the target value and actual combustion conditions.

In addition, the combustion information creating unit 33 creates, as advice information, information for instructing repair or replacement of the combustion equipment 10 or for predicting failure of the combustion equipment 10 .

In this embodiment, the combustion information creating unit 33 creates the specific information based on the measurement information obtained from the combustion equipment 10 so that the combustion equipment 10 can be constantly monitored. Then, the combustion information creation unit 33 creates advice information related to maintenance of the combustion equipment 10 based on, for example, trends of specific information with different specific times.

As a specific example, when the air ratio remains substantially constant for a certain period of time, the combustion information creating unit 33 creates advice information indicating that maintenance of the combustion facility 10 is not particularly required. On the other hand, if the air ratio tends to increase gradually over a certain period of time, it is possible that a predetermined location in the combustion facility 10 has deteriorated. In this case, the combustion information creation unit 33 creates advice information for prompting the user to perform maintenance of the combustion equipment 10 .

Further, the combustion information creating unit 33 creates advice information for notifying the user that air is entering the furnace chamber 11 from the outside based on the difference between the combustion air ratio and the burner air ratio. Note that the combustion information creating unit 33 of the present embodiment notifies the user when the difference between the combustion air ratio and the burner air ratio becomes equal to or greater than a predetermined threshold value.
Further, when the difference between the combustion air ratio and the burner air ratio tends to increase gradually during a certain period of time, the combustion information creation unit 33 considers the possibility that the airtightness of the combustion equipment 10 has deteriorated. Create advice information such as

Furthermore, the combustion information creating unit 33 creates advice information using the combustion information of the one combustion facility 10 and the combustion information of another combustion facility that is different from the one combustion facility 10 .
For example, the combustion information creating unit 33 may obtain information on the transition of the combustion air ratio and the timing of failure occurrence in other combustion equipment. When the combustion information creation unit 33 determines that the transition of the combustion air ratio of the target combustion equipment 10 is similar to the transition of the combustion air ratio of the other combustion equipment, in the future, one combustion equipment It is predicted that the facility 10 may also fail. In this case, the combustion information creation unit 33 creates advice information indicating that there is a possibility that a failure will occur at a predetermined time regarding one combustion facility 10 .

In addition, when determining another combustion facility to be compared with the combustion information of one combustion facility 10, the combustion information creation unit 33 uses the combustion facility information of the combustion facility 10 to determine whether the content of the combustion facility information is the same or similar. You may make it compare the combustion facilities which carry out. For example, the combustion information generator 33 may compare one combustion facility 10 with another combustion facility having the same or similar specifications such as fuel type information, facility attribute information, and burner attribute information.
Note that the combustion information creating unit 33 can acquire the combustion equipment information by referring to the equipment information storage unit 32 . Further, the combustion information creating unit 33 can acquire combustion information of other combustion equipment by referring to the combustion information storage unit 34 .
