Global Re-Fuel Furnace on Rohrer Farm, Lancaster County, Pennsylvania and Weaver Farm, Pendleton County, West Virginia

The Technology

The Global Re-Fuel furnace (PLF-500) by Wayne Combustion Systems was installed on two farms in 2014 as demonstration projects for the Farm Manure-to-Energy Initiative. The furnace uses poultry litter as a fuel and was designed to deliver heat via hot air to poultry housing.

The Farms

Mark Rohrer’s poultry houses in Lancaster County, PA, are on land that has been farmed by his family for generations. Mr. Rohrer owns two broiler houses with a solar panel array to offset the poultry operation’s electricity usage. He purchases propane independently and, except for a modest contribution from the integrator, pays for heating out-of-pocket. (See upper slideshow)

Mike Weaver grows broiler chickens in two poultry houses in Pendleton County, WV, that are retrofitted with energy efficiency improvements. His farm includes a pond, 80 acres of pastures, and upland wildlife habitat conservation. The farm produces approximately 300 tons of excess litter every year that are stored in the covered litter shed and sold off of the farm. (See lower slideshow)

Performance Evaluation

The Global Re-Fuel combustion system was evaluated for technical, environmental, and financial performance. An overview of the findings is available in the main body of the 2016 Final Report. Details are in Appendix A.

The report includes an evaluation of air emissions from three thermal manure-to-energy systems, as well as the potential for transporting and marketing the ash co-product as a crop fertilizer.
