Failure analysis and fatigue performance assessment of titanium diaphragms used in sonic soot blowers

Sonic soot blower, utilizing an oscillating diaphragm, generates acoustic waves for cleaning of equipment such as boiler and furnace to increase their efficiency. Based on earlier research by NRI (Niroo Research Institute), one of the main reasons disrupting the regular function of sonic soot blower is the failure of the diaphragm. The failure of circular Ti-6Al-4V sheets employed as the diaphragms is investigated by using SEM images. Based on...
