Abstract
A continuous hog fuel drying pilot plant based on the principle of mixing hog fuel with a hot oil (e.g., crude tall oil) as the heat transfer medium, and recirculating the suspension through a steam heated exchanger was designed, built, and successfully operated. The drying process proposed is based on the principle of vapour recompression. The capacity of the pilot plant is approximately 2.5 kg/h of hog fuel (dry basis) and the effective heat exchanger area is 0.4 m2. Densification options are being studied to produce a water-resistant densified biomass fuel.
