 Waterwall Tubeskin Thermocouple
Chemical cleaning to remove scale from inner surface of boiler tubes has periodically been conducted to prevent accidents of overheating, hydrothermal eruption and blowout breakage. In order to minimize the cleaning frequency, appropriate grasp of timing of the chemical cleaning is important, and accurate temperature measurement of waterwall tubes is required. “Embedded-in-Grooves” type waterwall tubeskin thermocouples, co-developed with the Central Research Institute of Electric Power Industry in Japan for high durability, accuracy and workability, have been widely used by customers.

Measurement Accuracy
Fig.1 shows the "Embedded in Grooves"
type thermocouple measured in agreement
with the actual tube surface temperature
and two other types of thermocouples,type I
and type II ,measured much higher than that.
