Abstract/Description

1NICOLE STATES, CLAYTON KEISER, JASON ROBERTSON and BOMMANNA LOGANATHAN Department of Chemistry and Watershed Studies Institute, Murray State University and Hutson School of Agriculture, Murray State University, Murray, KY 42071.

Murray State University’s Hutson School of Agriculture has installed a new 500 kBTU/hr biomass burner (BB500 Bio-Burner, LEI Industries, Madisonville, KY) at the Farm Center during the Fall2014 to evaluate various crops and biomass materials as energy sources. Experimental burning of various feedstocks including wood chips, sorghum, equine manure, switchgrass and hemp samples were conducted during Spring 2015. Amount of feedstock burned ranged from 765 kg to 1255 kg. The amount of ash collected varied from 2 kg to 120kg. The mineral analysis in the ash samples were performed following the procedure of ASTM D3682. Oxides of Si, Al, Ti, Fe, Ca, Mg, K, Na, S, P, Sr, Ba, Mn were measured. Results revealed that the mineral composition of ash samples varied with different feedstocks burned. Among various minerals measured, silicon dioxide had the highest amount per kg of ash (430-710g/kg) followed by calcium oxide (53-300g/kg) in almost all of the ash samples tested. Strontium oxide had the lowest amount (0.2-1.1g/kg). Among the various feedstocks, energy sorghum contained the highest amount (710g/kg) of silicon dioxide. Equine manure contained the highest amount (300g/kg of ash) of calcium oxide.
