In recent years, a microcomputer has been incorporated in a boiler, and it has become possible to measure and record boiler can water data (electrical conductivity, pH, etc.) at predetermined intervals.
The recorded boiler can water data is sent to the management station side computer, for example, once a day for 24 hours, and the management station side computer records this data. Then, the computer on the management station side accumulates boiler can water data for a certain delimited period (may be one month or one year), and this data and the optimal water treatment state are made into rules, and the knowledge base is made into a knowledge. Based on the above, the inference engine is started to infer the quality of the current water treatment and the improvement points, and the inference result is transmitted to the boiler. When the boiler side microcomputer receives the improvement point, it performs an operation to change the water treatment control set value,
Optimal water treatment conditions can be realized.
