Abstract:

 

An apparatus was designed that enables the testing of boiler tubes against   erosion. The apparatus makes use of a tube sample and simulates conditions   similar to those prevailing in boilers in lignite-based power plants. The   apparatus is composed of 3 components: a furnace for heating the sample, a   loading system that allows the application of tensile stresses while   allowing its rotation, and an erosion unit that delivers abrasive particles   to the surface of the sample. The unit, as designed, would allow testing of   boiler tubes up to a temperature of 650 °C and particle velocities   of up to 50 m/s. The apparatus, tested at room temperature for 4 identical   samples, yielded very similar erosion values, which were based on   measurement of weight loss. At elevated temperature, erosion could be   followed by a thickness loss value rather than the weight loss since the   oxidation complicates the weight measurements. Two economizer materials   (P235GH and 16Mo3) were tested with the current setup at 500 °C   with particle velocity of 10 m/s. The testing showed 16Mo3 performed better   than P235GH did, the erosion rate of the former being 20% lower than the   latter.
