Poultry litter is a more challenging fuel than wood for several reasons. The ultimate analyses (Table 1) indicate some of the reasons. One reason is that the nitrogen content is about 10 times higher in poultry litter than wood. This increases the potential for fuel NOX emissions and requires special measures to reduce these emissions. The sulfur content of poultry litter is more than 10 times higher than that of wood. This increases the potential for SOX emissions and requires special measures to reduce these emissions. Chloride levels are higher in poultry litter than in wood. High chloride levels, in conjunction to high alkali levels, increase the potential for particulate emissions, corrosion problems, and acid gas emissions, and requires special measures. Ash levels are much higher in poultry litter than in wood, requiring higher-volume ash-handling equipment and more attention to particulate removal, slagging, and fouling.
