- a drainage means for draining a temperature detection means for detecting the temperature of the evaporation vessel, and a control means for controlling the heating means, the water supply means, the drainage means, etc., and the temperature of the evaporation vessel after completion of the steam generation operation. After the temperature of the evaporator drops to a predetermined temperature, the residual water in the evaporation container is drained.
- the evaporating container is sufficiently filled with water until the temperature becomes equal to or lower than the predetermined temperature, so that the drying of the water is mainly from the water surface and the drying on the wall surface does not occur.
- the water adhering to the walls of the evaporating vessel dries, but since it dries at a predetermined temperature or less, it is possible to suppress the growth of the scale, and the adhering scale is easily peeled off at the next operation to remove the volume. Accumulates on the bottom of the vessel. This deposited scale is removed by draining after the operation is completed.
- the predetermined temperature was 60 ° C or less. If the temperature at which the water is dried exceeds 60 ° C, the crystallization of the scale will be accelerated rapidly.Therefore, filling the water until the temperature becomes 60 ° C or less will prevent the crystallization of the scale. It becomes possible.
- the water remaining in the evaporation container may be drained, and the water may be supplied into the evaporation container. Since the water in the evaporator at the end of heating is close to 100 ° C
- the temperature of the evaporation container can be reduced in a short time by adding normal-temperature water.
- the temperature of the evaporating vessel is at least 100 ° C or higher, and the water remaining in the evaporating vessel is at a temperature close to ioo ° c, and it takes time s until the temperature becomes lower than the predetermined temperature. Therefore, the time required to reach the predetermined temperature can be further reduced by forcibly cooling the evaporating container with the cooling fan.
- a predetermined amount of water may be added to the evaporation container.
- a predetermined amount of water may be added to the evaporation container.
- the evaporating vessel is cooled and drained after the evaporating vessel reaches a predetermined temperature. Since the drying takes place below the temperature, the adhesion to the evaporating vessel is reduced by suppressing the crystallization of the scale, and the attached scale is easily peeled off at the next operation and deposited on the bottom of the container. Since the deposited scale is removed by draining after the operation is completed, it is possible to prevent clogging and a decrease in evaporation capacity.
