Energy Valorization of Swine Manure by Oxygen Carrier Aided Combustion (Ocac) with Oxygen Carriers Based On Natural Ores
Short Introductive summary
Organic waste such as swine manure is potentially valuable and commonly used as fertilizer but its indiscriminate use can lead to important environmental problems, such as soil and groundwater contamination and the emission of greenhouse gases. Among the new technologies for turning these wastes into energy, Oxygen Carrier Aided Combustion, OCAC may be a promising alternative. In the OCAC process, the commonly used bed material, silica sand, is replaced by oxygen carriers, acting as an oxygen storage medium, which results in an advantage for the combustion process. The objective of this study is to evaluate the effects of temperature (800-900 ºC) and excess oxygen (1-3vol.% of O2 in the exit gas stream) on combustion efficiency and also to analyze the distribution of emissions of nitrogenous compounds in the Oxygen Carrier Assisted Combustion (OCAC) process.
