Scale thickness estimating system, scale thickness estimating method, and scale thickness estimating program

A scale thickness estimating method, the method comprising:

• acquiring, by a thermocouple penetrating an outer surface of a member that form a flow path of a fluid, a temperature of the fluid;
• measure, by a thermometer, a temperature of the outer surface of the member;
• acquiring, by a heat flux, a heat flux on the outer surface of the member;
• acquiring, by a processor, a flow path wall thermal conductivity of the member;
• acquiring, by the processor, a scale thermal conductivity of scale depositing on an inner surface of the flow path;
• and
• estimating, by the processor, a thickness of the scale based on the temperature of the fluid, the temperature of the outer surface, the heat flux, the flow path wall thermal conductivity, the scale thermal conductivity and a thickness of the member.

A non-transitory computer-readable storage medium storing a scale thickness estimating program causing a computer to perform a method, the method comprising:

• acquiring a temperature of a fluid flowing in a flow path from a thermocouple penetrating an outer surface of a member that forms the flow path;
• acquiring a temperature of the outer surface of the member from a thermometer;
• acquiring a heat flux on the outer surface of the member from a heat flux meter;
• acquiring a flow path wall thermal conductivity of the member;
• acquiring a scale thermal conductivity of scale depositing on an inner surface of the member;
• and
• estimating a thickness of the scale based on the temperature of the fluid, the temperature of the outer surface, the heat flux, the flow path wall thermal conductivity, the scale thermal conductivity and a thickness of the member.
