1. A scale thickness estimating system, the system comprising:
a thermocouple configured to penetrate an outer surface of a member that forms a flow path of a fluid and acquire a temperature of the fluid flowing in the flow path;
a thermometer that measures a temperature of the outer surface of the member;
a heat flux meter that acquires a heat flux on the outer surface of the member; and
a processor configured to:
acquire a flow path wall thermal conductivity of the member;
acquire a scale thermal conductivity of scale depositing on an inner surface of the member; and
estimate 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.
