In 2014 Froling Energy opened it’s first fuel plant in Peterborough, NH where we were the first to produce a new kind of biomass fuel: the screened semi-dry wood chip. PDCs, as we call them, were first produced here using a 1 million BTU/hour Italian wood chip furnace in a “fluid bed” batch dryer: We would load the drying room 6 feed deep with screened green chips and wait 3 to 4 days for them to be dried down to 25% moisture content. We soon found that this method severely limited our output so after two winters we devised and installed a better system.
Our improved plan involved installing a large wood chip boiler that would heat a 60 foot long, continuous-feed belt dryer. The system was up and running by the fall of 2016. The Viessmann Vitoflex 300-UF Model KPT-950 with a maximum output of 3.2 million BTUs per hour did a great job for 5 more winters. However, its output was limited to about 6000 tons per year.
Due to ever growing demand, a new larger plant was built on 10 acres in Keene, NH during the summer of 2020, operational by December. See Project page on our new Keene Plant.
The Peterborough site has been dismantled and fully abandoned.
All operations are now at 20 Manchester Street in Keene.
