PROBLEM TO BE SOLVED: To provide a scale adhesion determining device for a boiler, which can accurately determine the adhesion of scale to a water pipe. ! SOLUTION: A scale adhesion determining device has a plurality of water pipes 12 into which boiler water is supplied, and determines the adhesion of scale to the water pipes 12 in a boiler 1 which heats the pipes 12 and generates vapor from the boiler water. The scale adhesion determining device includes: a temperature sensor 110 for measuring the surface temperature of the water pipes 12; a water level sensor 120 for measuring a water level of the boiler water supplied to the water pipes 12; a scale adhesion determining portion 130 for determining that the scale is adhered when the surface temperature of the water pipes 12 measured by the temperature sensor 110 exceeds reference temperature; a difference calculating portion 140 for calculating the difference in height between the water level measured by the water level sensor 120 and a position at which |
