Agriculture is one of Canada’s largest industries and the residues left over from farming, milling and the off spec crops that are produced every year are present across the country. The quantity and quality of these residues as potential fuels have been analysed, including a comparison of the financial benefits and costs to selecting agricultural feedstocks for heat and power projects. A variety of fuels have been assessed, including raw and densified biomass, to understand the range in transportation costs, front and back end material handling and boiler selection. These fuels include: corn stover, corn cob, switchgrass pellets, whole canola, dried distillers grain, beans, flax chives and oat hull pellets. Analytical results show which fuels are most apt to cause clinkering, however, boiler design and operation can minimize down time from ash issues. Agricultural fuels can be suitable for specific applications provided appropriate pre treatment and handling are followed.
