TerraSource Global’s Jeffrey Rader® TubeFeeder was recently featured as a spotlight in Biomass Magazine. Learn more about how this unique system provides many advantages for biomass facilities.
Fuel preparation is vital for efficient combustion, which is a critical component to the overall profitability of biomass energy plants. Many factors, however, must be accounted for to ensure quality fuel preparation, such as controlling dust, removing foreign and oversized particles, and ensuring appropriate material storage and high-quality homogenization. TerraSource Global’s Jeffrey Rader® TubeFeeder system uses innovative technology to thoroughly and cost-effectively handle all of these challenges, making it an integral component for reclaiming biofuel from silos or storage piles at the most efficient biomass facilities.
TubeFeeders offer full homogenization at a uniform rate of fuel, while maintaining substantially lower power consumption compared to alternative solutions. Over 100 TubeFeeders are installed worldwide, primarily in pulp and paper and bioenergy operations. However, TubeFeeder technology is also a viable reclaiming option for several other applications beyond forest products, including coal, cement, pellets and many others. With the increasing demand for sustainable bioenergy, the TubeFeeders have gained a reputation for being the optimal solution for companies operating in this market.
A TubeFeeder is composed of an outside tube with uniform slots spread along the length of the machine, which is key to controlled combustion. Pile height is not an issue, as TubeFeeders are easily adaptable to desired height and silo volume. Conveying occurs by gravity flow through the slots, which helps diminish the required operational power by at least 70% compared to other, conventional systems. Each slot is furnished with an “activator.” The intelligent design employed in the tube and screw configuration constitutes a “closed forces system,” meaning no thrust forces into the structure are generated.
As the tube rotates, material is reclaimed into it. Material being conveyed inside the tube is protected from the static pressure exerted by the remaining material in the pile/silo. Tube rotation is controlled by variable frequency drive, and the typical span is 1-6 rpm, allowing for uniform material reclaiming and blending along its length. A screw auger operates inside the tube at a fixed rpm, conveying fuel to the outlet end. Capacity is proportional to the tube rotation speed, with a 15-100% repeatable rate within a selected capacity window. Tube rotation depends on travelling direction, thereby ensuring consistent operation regardless of travel direction. The whole unit traverses on rails across the base of square silos or in round silos on a swivel around the center.
Overall, biomass facilities can expect major performance and operational advantages by choosing the TubeFeeder as the critical component of their storage and reclaim solution:
