Experimental investigation on the influence of ambient pressure on twin-fluid atomization of liquids with various viscosities

Abstract (englisch):
Twin-fluid atomization for combustion application has been investigated over the years for a wide range of operating conditions and typically low viscous liquids. Nevertheless, little has been published concerning twin-fluid atomization for entrained flow gasification (EFG) application. Twin-fluid atomization for EFG is connected with several challenges arising from the specific technical operating conditions. Typically, the system operates by gasifying high viscous liquid or suspension fuels featuring viscosities up to 1000 mPa s and complex rheolog-ical behavior. Additionally, the atomization of such fuel is performed at elevated ambient pressure (up to 80 barabs) due to the subsequent process step.
Detailed investigations applying state of the art measuring techniques on the atomization of high viscous liquids using external mixing twin fluid atomizers at increased ambient pressure are scarce. Research work pre-sented is therefore focused on the atomization of liquids within a wide range of viscosities at increased ambient pressure. The experiments in the current study were conducted at several pressure stages (1 – 21 barabs) at ... mehr
