Performance of a Vertically Fed Compost Reactor

Development and validation of mathematical model for aerobic composting process

“…An increase of degradation rate simultaneously demands an increase of airflow rate that may cool the reactor. It is not still clear where the optimum in this compromised situation is [64].…”

Sensitivity Analysis and Parameter Optimization of a Heat Loss Model for a Composting System

“…While the impact of the variation in the thickness of insulation on the rate and amount of heat lost (Lemus and Lau, 2002;Lyberg and Hogland, 2004) to the surroundings by the composting system is clear in the sense that a thicker layer of insulation will limit the heat loss rates, the interaction of free airspace and internal reactor diameter in controlling heat removal from the matrix is more intricate. The porosity and internal diameter will interact to influence the structural parameters of the compost matrix (compaction, free airspace itself, and permeability (Veeken et al, 2003).…”

“…T s T s was tested in the range 25.0°C to 75.0°C (298 to 348 K) since this range corresponded to temperatures that were recorded in various composting experiments (Marugg et al, 1993;Kaiser, 1996;Das and Keener, 1997;Korner et al, 1997;Nakasaki et al, 1997;Day et al, 1998;Fauci et al, 1999;Raviv et al, 1999;Robinzon et al, 1999;Vuorinen and Saharinen, 1999;Lemus and Lau, 2002;Venelampi et al, 2003;Hess et al, 2004;Ekinci et al, 2004b;Hong and Park, 2004;Lyberg and Hogland, 2004;Mohee and Mudhoo, 2005;Ghaly et al, 2006).…”
