In order to precisely monitor the inner-flue tube wall temperature of the boiler platen super-heater, the temperature measurement test of inner-flue and outer-flue tube wall has been carried out.
temperature superheater tube. The material used for this HTS tube is A213-T91 which is similar to modified 9Cr-1Mo steel. For the tube thickness, the allowance range is - 0% to +33% depends on the location of tubes in the boiler. The minimum thickness requirement of tubes is 3.85 mm,
05/02/2018 · The maximum outer tube-wall temperature is 571.2 °C, which is still smaller than the allowable temperature of the tube metal. Therefore, it is reasonable to believe that abnormal over-temperature in the water wall tube is unlikely to happen at the designed operating load.

In order to precisely monitor the inner-flue tube wall temperature of the boiler platen super-heater, the temperature measurement test of inner-flue and outer-flue tube wall has been carried out. And the data of inner-flue and outer-flue tube wall temperature was acquired in real time. According to the experimental data, the correlative rule about inner-outer flue tube wall temperature was
A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure. Components typically
