Recently Jeffrey Rader Corporation has been selected as supplier of Alternative Fuel Boiler Feed Systems in Virginia City, Virginia and Jeonju, Korea . Though separated by half a world, both systems hold one thing in common: they use woody biomass and/or waste materials as part of a global quest for alternative fuels in power generation.

The system in Korea  is part of a 100MW cogeneration project that will supply power and process steam for a newsprint mill.

It replaces an older coal fired boiler with a new grate fired system with a bubbling fluidized bed design. This alternative fuels system is capable of firing a mixture of waste products such as bark, Refuse Derived Fuel (RDF) pellets, DIP sludge and plastics rejects from the mill’s recycled fiber process.

Jeffrey Rader’s material handling and boiler feed system will supply more than 30 tons per hour of waste fuels to the BFB Boiler. The system employs pneumatic conveyors to transport fuel to a receiving hopper, which then distributes fuel into two boiler house mounted storage silos. Fuel is then reclaimed with screw reclaimers and distributed and metered into four infeed points around the boiler.

On the other side of the globe, Jeffrey Rader is supplying a biomass utility boiler feed system in Virginia City, Virginia. The system will be part of a 650MW power generating plant that will supply power for commercial and residential use. The system will supply woody biomass directly to the boiler where a mixture of coal and wood will be used for fuel.

Four identical boiler feed systems will supply more than 195 tons per hour of wood chips and forest residuals to two boilers. The system accepts pre-sized material from a conveyor and meters it into the boiler with high accuracy and reliability.

Jeffrey Rader brings to the Virginia City and Jeonju power projects their significant experience in handling woody biomass, RDF, sludge and pellets in the Pulp & Paper Industry. This experience is increasingly valued by many in the power industry who are looking to add more biomass into their standard fuel stream, which is typically coal.

In addition to mechanical feeding systems, Jeffrey Rader has developed a leadership position in the direct injection of biomass fuels in pulverized coal boilers. Jeffrey Rader recently contracted for the supply of 24 direct pneumatic injections systems to co-fire biomass with pulverized coal in the Drax Power Station in Selby, England. With a total capacity of 240 mtph, we believe this is the largest biomass/pulverized coal co-firing project of its kind.
