Abstract
A heating apparatus for supplying heated air to a dryer for grain or other particulate materials. The apparatus features a biomass furnace with a burn chamber for combustible biomass material, a chimney having a lower end in fluid communication with the burn chamber interior, and air ducting that has a fresh air inlet, an output end connected or connectable to the dryer, and is in in fluid communication with the chimney to enable redirection of said heated exhaust air from the chimney to the dryer via the air ducting. An airflow control system is configured to both control airflow to the dryer through the air ducting, and control a temperature of said airflow by varying a ratio between the fresh ambient air and the heated exhaust air.
