Combined Heat and BioChar Greenhouse Sized Unit
ClearStak and Ag Fuel Energy Systems NE have designed a greenhouse sized wood chip powered combined heat and biochar unit. It's set up for easy operation with fairly dry fuel. The thermostat uses a Nest system, and can link directly with an iPhone for alerts.
This systems is a two 600,000 BTU chip burning prototype that's still in the R&D phase. They hope to have a market ready biochar-producing unit available soon.
Ag Fuel Energy Systems NE distributde a Ag Fuel Multi-Fuel Furnace. They were developed as corn burners, which has been improved to burn pellets, corn wheat, rye , cherry pits and microchips. Most of their installations are in poultry applications and in greenhouses.
