Enhanced radiative transfer and heat recovery for combustion device

Abstract

A stove includes a combustion chamber for producing heat, a thermoelectric device thermally coupled to a hot source and a cold source, a battery, a fan electrically connected to the thermoelectric device and the battery, and a controller configured to monitor the battery and thermoelectric device and configured to direct the fan be operated from power provided from the battery when power produced from the thermoelectric device is insufficient to power the fan. The stove can have an associated heating plate, and the walls of the combustion chamber can be configured to reflect heat onto the heating plate.

1 . A stove comprising;
 a combustion chamber; and   a heating plate, wherein the combustion chamber includes one or more angled combustion chamber walls, wherein the angle of the one or more combustion chamber walls is configured to reflect heat produced in the combustion chamber onto the heating plate.   
     
     
         2 . The stove of  claim 1 , wherein the combustion chamber has a V-shape formed by the combustion chamber angled walls. 
     
     
         3 . The stove of  claim 1 , wherein the one or more angled walls are not horizontal. 
     
     
         4 . The stove of  claim 1 , wherein the one or more angled walls have a lower end toward a center of the combustion chamber and an upper end away from the center of the combustion chamber. 
     
     
         5 . The stove of  claim 1 , further comprising one or more air inlet ducts formed from a side of a combustion chamber angled wall. 
     
     
         6 . The stove of  claim 1 , further comprising combustion gas ducts and air inlet ducts, and a recuperator is located at a base section of the stove, wherein the recuperator thermally couples the combustion gas ducts to the air inlet ducts.
