  1. Median values shown for temperature and flue gas data during periods of stable combustion. Corresponding values for entire duration of combustion of fuel mixtures are shown in parentheses. Duration of combustion tests were approximately three hours, except for DDGS 100% (two hours) and DDGS-MRFR 90:10 (four hours)
