Manure Drying Optimization

SSRN Electronic Journal, 2021
Horse manure is a poor feedstock whose energetic content is comparable to that of herbaceous biomass. However, it can be effectively burnt provided that it is previously desiccated, being its moisture content very high (60% wb).This work reports an experimental investigation to identify optimal conditions for horse manure drying in a bench-scale direct
