The cost of harvesting is one of the constraints in improving biofuel economics. Adjusting the ground speed of harvesting machines to maximize their throughput rate in relation to yield level is one of the ways to reduce harvesting cost. To control the ground speed of a baler, a real-time sensor that can predict the swathed-biomass yield in front of the(More)
Previous studies highlighted the need to develop efficient harvesting and size reduction equipment for miscanthus. This study investigated the effect of blade oblique angles and cutting speeds on cutting energy. Cutting blade speed, before and after severing a single miscanthus stem, was used to calculate the cutting energy. The cutting energy was(More)
One of the reasons for relatively high biomass harvesting cost is challenges in adjusting the ground speed of harvesting machines with respect to the yield level within a field. A real-time biomass yield sensor that can predict the yield in front of a machine could be a useful tool to control ground speed. It was hypothesized that the force required to bend(More)
Impact cutting Harvesting Energycane Biomass Bioenergy Size reduction Energycane is a promising bioenergy crop for warm southeastern US regions and existing sugarcane machinery is being adapted for energycane cultivation. Because of energycane's comparatively higher fibre content and smaller stem diameters, the cutting blades must be optimized for(More)
Lignocellulosic biomass in bale form has a low bulk density. Current in-field balers can achieve a bulk density of merely 120 to 180 kg dry matter (DM) m−3, whereas modern high-compression cutting balers produce up to 230 kg m−3. Mechanical compression is a straightforward technique to increase the material density, which significantly improves the(More)
Miscanthus is emerging as a promising feedstock for domestic biofuel production. However, inefficiencies of the machinery that is used for harvesting bioenergy crops such as miscanthus currently prohibit commercial production. The performance of a mower-conditioner used to harvest miscanthus was evaluated, and modifications to the disk head were made to(More)
To achieve optimal use of transportation infrastructure in general, the bulk density of the material being transported must be such that the containment structure reaches its weight and volume limits simultaneously. As an example, " gondola type " coal railcar dimensions are designed to precisely accommodate the density of coal in a pile, which is 850 kg m(More)
