Portable fireplace

A method for burning combustible fuel, the method comprising:

• providing a structure comprising:
• an outer wall defining a lower portion and a tower portion;
• an inner wall separated from the outer wall by an air gap and defining a combustion chamber within the lower portion and a chimney within the tower portion;
• a fireplace aperture through the outer wall and inner wall;
• a mantel disposed below the fireplace aperture and projecting outward from the outer wall;
• a plurality of inlet ventilation holes disposed in the lower portion of the outer wall;
• drawing air in through the plurality of inlet ventilation holes;
• expelling a first portion of the air into a lower portion of the combustion chamber to support primary combustion of a fuel;
• and
• expelling a second portion of the air into an upper portion of the combustion chamber to support secondary combustion of gases, smoke, or soot emitted by the fuel during primary combustion.

A system for burning combustible fuel to provide light and heat, the system comprising:

• a double-walled body defining a lower portion and a tower portion;
• a combustion chamber disposed within the lower portion;
• a chimney disposed within the tower portion;
• an air gap disposed between walls of the double-walled body;
• a fireplace aperture disposed within the tower portion;
• a mantel disposed below the fireplace aperture and projecting outward from the double-walled body;
• a plurality of inlet ventilation holes disposed in an outer surface of the lower portion;
• a plurality of outlet ventilation holes disposed in an inner surface of the combustion chamber;
• a base different than the double-walled body and disposed at a bottom of the double-walled body;
• a flow redirector disposed within the chimney above the fireplace aperture;
• a removable fuel grate disposed within the combustion chamber;
• and
• a removable ash pan disposed below the removable fuel grate.

A portable fireplace for burning combustible fuel, the portable fireplace comprising:

• a lower portion comprising:
• an outer wall;
• and
• an inner wall separated from the outer wall by an air gap and defining a combustion chamber;
• a fuel grate configured to support fuel and defining a portion of the combustion chamber;
• a chimney disposed above the lower portion, the chimney being arranged to draw smoke from the combustion chamber therethrough;
• a fireplace aperture in one of the lower portion and the chimney, the fireplace aperture being disposed at an elevation above the fuel grate and providing visual, lateral access to an interior of the combustion chamber;
• an inlet ventilation hole in one of the lower portion and the chimney, the inlet ventilation hole being configured to draw air from outside the portable fireplace and into the air gap between the outer wall and the inner wall;
• a first outlet ventilation hole configured to introduce drawn air at an elevation below the fuel grate to feed flames of fuel on the fuel grate and generate a primary burn of the fuel;
• and
• a second outlet ventilation hole disposed in the inner wall to introduce air into the combustion chamber at an elevation above the fuel grate to accommodate a secondary burn of the fuel, the second outlet ventilation hole being in fluid communication with the air gap between the outer wall and the inner wall and with the inlet ventilation hole and configured to provide air for passage through the chimney.

A portable fireplace for burning combustible fuel, the portable fireplace comprising:

• an outer wall;
• and
• an inner wall separated from the outer wall by an air gap and defining a combustion chamber;
• a fuel grate configured to support fuel and defining a portion of the combustion chamber;
• a fireplace aperture through both the inner wall and the outer wall, the fireplace aperture being disposed at an elevation above the fuel grate and providing visual, lateral access to an interior of the combustion chamber;
• an open top configured to pass convective heat when fuel is burned on the fuel grate;
• a first outlet ventilation hole configured to introduce air into the combustion chamber at an elevation below the fuel grate to feed flames of fuel on the fuel grate and generate a primary burn of the fuel;
• and
• a second outlet ventilation hole disposed at an elevation above the fuel grate to accommodate a secondary burn of the fuel, the second outlet ventilation hole being in fluid communication with the air gap between the outer wall and the inner wall.
