Abstract: A system for drying grain includes a receiving bin defining a cavity therein and further includes intake and outlet ports. A conduit is operably connected to the receiving bin that includes a plurality of check valves and a stop valve. The system further includes a mechanism for introducing air at a selected flow rate into the conduit and a combustion source that includes a pilot gas light wherein fire is created that burns between 2000–3000 degrees Fahrenheit. The combustion source includes a flue positioned thereabove and a drain outlet extending substantially orthogonal to the conduit. A heat exchanger is connected to the combustion source including a fan and a filter operably connected thereto.
