Co-gasification of blended coal with feedlot and chicken litter biomass Conference Paper uri icon


  • Fixed-bed gasification has been described as a technology for utilizing animal waste as a source of renewable energy, which can reduce its disposal problems and associated pollution issues. Fixed-bed co-gasification studies on coal and animal waste-based fuels like feedlot biomass (cattle manure), and chicken litter biomass have been experimentally studied under batch mode operation. A simplified phenomenological analysis yields a linear correlation for correlating the average oxidation-front propagation velocity with the fuel properties and the airflow rate. The fuel-ash plays an important role in determining the rate of oxidation-front propagation in the fuel-bed. The product gas heating value was almost uniform for all the fuels, and could be attributed to almost uniform exit product gas compositions. It is feasible to co-gasify animal waste-based fuels like feedlot biomass and chicken litter biomass with coal. This might not only reduce their disposal problems, but also reduce emission of greenhouse gases, as these are CO2 neutral fuels. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
