Abstract

An example heat recovery apparatus includes a chimney configured to exhaust air and smoke from a biochar kiln combustion chamber. The example heat recovery apparatus also includes a heat exchanger configured to recover heat from the chimney and provide the heat to a secondary application.

Claims

exact text as granted — not AI-modified
1 . A heat recovery apparatus, comprising:
 a chimney configured to exhaust air and smoke from a biochar kiln combustion chamber; and   a heat exchanger configured to recover heat from the chimney and provide the heat to a secondary application.   
     
     
         2 . The heat recovery apparatus of  claim 1 , wherein the heat exchanger is configured to exchange heat from one volume of air to another volume of air. 
     
     
         3 . The heat recovery apparatus of  claim 1 , wherein the heat exchanger is configured to exchange heat from a volume of air to a volume of liquid. 
     
     
         4 . The heat recovery apparatus of  claim 1 , wherein the heat exchanger is configured to exchange heat from a volume of air to a volume of steam. 
     
     
         5 . A heat recovery apparatus, comprising:
 a chimney configured to exhaust air and smoke from a biochar kiln combustion chamber;   a heat exchanger configured to recover heat from the chimney and provide the heat to a secondary application, the heat exchanger further configured to exchange heat from one volume of air to at least one other medium   
     
     
         6 . The heat recovery apparatus of  claim 5 , wherein the at least one other medium is air. 
     
     
         7 . The heat recovery apparatus of  claim 5 , wherein the at least one other medium is liquid. 
     
     
         8 . The heat recovery apparatus of  claim 5 , wherein the at east one other medium is steam. 
     
     
         9 . A heat recovery apparatus, comprising:
 a chimney configured to exhaust air and smoke from a biochar kiln combustion chamber;   a heat exchanger configured to recover heat from the chimney and provide the heat to a secondary application, the heat exchanger further configured to exchange heat from one volume of air to at least one of air, liquid, and steam.
