Abstract (englisch):

High pressure entrained flow gasification, where low-grade anthropogenic and biogenic fuels are converted into a high quality syngas (CO + H2), is one of the key enabling technologies for a future circular economy and a sustainable use of resources. The syngas subsequently can be used for the synthesis of chemicals or serve as fuel in an IGCC power plant. To guarantee for complete conversion of those low-grade fuels, as well as for a high quality syngas (no soot or residual hydrocarbons), the droplet size and the related flow field, generated by the burner nozzle of the gasifier, play a major role. A variety of experimental investigations focused on atomization and gasification is essential for the design and development of a suitable burner nozzle.
The present study is focused on the development steps, necessary for the design of a new high-pressure entrained flow gasifier burner nozzle, applicable for the gasification of low-grade anthropogenic fuels. Experimental investigations focused on liquid mass flow scaling of gas-assisted atomizers are presented, to get a deeper insight into one step of the burner design process.
Typically, spray investigations are performed at lab scale, featuring only low liquid mass flow rates, thus knowledge concerning mass flow scaling of gas-assisted burner nozzles towards industrial throughput range is scarce. ... mehr
