Multi-functional Biomass and Other Combustibles stove

Abstract

A multi-fuel & multi-purpose fired stove which includes a burn chamber with an adjustable vertical or reciprocating grate ( 34 ) that allows for variable fuel delivery having a modular grill chamber 131, modular biomass/bio char bins ( 11 ), modular chimney composed of glass, steel or other types of chimney material 121. The multi-purpose stove is design for detachable or permanent fixtures used for a variety of purposes such as, heating, thermoelectrically generation, production of wood gas, distillation, dehydration of organic materials, and smoking of organic materials. The stove allows for customizing different types of fuels and different burning modes. The stove maybe run in top lite updraft mode, down draft stratify mode, cross draft mode, rocket stove or a combination of all four.

         1 . A stove comprising:
 a. a combustion chamber having a top, side and bottom opening,   b. an internal compartment inside said combustion chamber to allow secondary air in different proportions into the said combustion chamber which can be adjusted to have complete combustion or incomplete combustion to produce syngas inside the said combustion chamber wherein said combustion chamber can function as a pyrolysis chamber, super-heated air mixing chamber and combustion chamber,   c. a feed fuel hopper wherein said fuel hopper has a door to allow solid fuel to be inserted into said hopper with said door having an adjustable vent to allow primary or secondary air to flow into combustion chamber where said fuel consisting of but not limited to chipped wood, chuck wood, pelletized wood, sawdust, wood shaving, grassing, forbs, combustible plastics and fossil fuels,   d. a means to control a primary grate which controls the flow of air and said fuel between said fuel chute and the combustion chamber such that a plurality of combustion modes are possible such as but not limited to rocket stove mode, top lite up draft mode, down draft mode, and cross draft mode in which individual or combinations of said modes of combustion are possible,   e. a secondary grate that allows primary air and secondary air into said secondary grate.   
     
     
         2 . A stove comprising:
 a. A combustion chamber having a top, side and bottom opening,   b. an internal compartment inside said combustion chamber to allow secondary air in different proportions into the said combustion chamber which can be adjusted to have complete combustion or incomplete combustion to produce syngas inside the said combustion chamber wherein said combustion chamber can function as a pyrolysis chamber, super-heated air mixing chamber and combustion chamber,   c. a feed fuel hopper wherein said fuel hopper has a door to allow solid fuel to be inserted into said hopper with said door having an adjustable vent to allow primary or secondary air to flow into combustion chamber,   d. a mean of vaporizing water and adding said vaporized water to said combustion chamber,   
     
     
         3 . A stove heat exchanger comprising:
 a. a combustion chamber,   b. a inner chimney in said combustion chamber wherein said inner chimney can be a fixed length or have a means to change the length depending on the rate of combustion desired,   c. an outer chimney connected to said combustion chamber to expel exhaust gases to atmosphere,   d. a external and or internal cooling fluid system inside said combustion chamber to extract additional heat to be used for a multitude of purposes,   e. the inner chimney inside of the said combustion chamber creates a cold air restriction to stop or reduce the amount of outside air going back into said combustion chamber when stove is not burning.   
     
     
         4 . A stove has a heat exchanger comprising:
 a. an external chamber connected to said stove top which allows combustion gases to expand wherein said external chamber may have glass or steel panels,   b. an inner down draft chimney in side said external chimney that allows combustion gases to flow,   c. an exhaust port for the down draft chimney,   d. a external up draft chimney that is connected to the said exhaust port of the down draft chimney for exhausting combustion by products.   
     
     
         5 . A stove as in claimed  claim 1  in which a plurality of attachment utilizing hot combustions gas and or syngas may be added to said chimney or said top opening wherein said attachments to consists of but not limited to a grill, syngas generator, oven, hot water heat exchanger, dehydrator, patio heater, hot combustion air attachments, steam engines and thermoelectric generator.
