Autothermal two-stage gasification of low-density waste-derived fuels
Hamel, Stefan; Hasselbach, Holger; Weil, Steffen; … - In: Energy 32 (2007) 2, pp. 95-107
In order to increase the efficiency of waste utilization in thermal conversion processes, pre-treatment is advantageous. With the Herhof Stabilat® process, residual domestic waste is upgraded to waste-derived fuel by means of biological drying and mechanical separation of inerts and metals. The...

Pilot study on jetting pre-oxidation fluidized bed gasification adapting to caking coal
Zhang, Juwei; Zhao, Zhigang; Zhang, Guangyi; Xi, Zeng; … - In: Applied Energy 110 (2013) C, pp. 276-284
Caking coal is difficult to be gasified in fluidized bed (FB) because of the inevitable particle agglomeration caused by caking in the dense bottom of the bed. Literature studies have shown that pre-oxidizing the coal can suppress its caking propensity, while quick dispersion of coal particles,...
