Abstract
The experimental studies are carried out to find the erosion rate of annealed SA192 low carbon steel bank tube and normalized SA 192 low carbon steel bank tube using fly ash particles of different size, velocity impingement angle and feed rate. Erosion rates are evaluated with different impingement angles ranging from 15° to 90°,at four different velocities of 32.5 ,35,37.5 and 40 m/s and four feed rates of 2,4,6, and 8 g/min. The erodent used is fly ash particles of different sizes ranging from 50250 µm of irregular shapes. In all the experimental conditions of fly ash particles it is found that the erosion rate of low carbon steel normalized bank tube is higher than annealed tube.
