Furnace fireplace apparatus for burning a variety of fuels, comprising, in combination:
- firebox means comprising a primary combustion chamber, including
- floor plate means,
- first and second side walls secured to the floor plate means and spaced apart from each other,
- front wall means secured to the floor plate means and to the first and second side walls,
- a rear wall spaced apart from the front wall and secured to the floor plate means and to the first and second side walls,
- a ceiling plate spaced apart from the floor plate means and secured to the front wall, the rear wall, and the first and second side walls;
- a bottom plate disposed beneath and spaced apart from the floor plate means;
- outer wall means disposed about and spaced apart from the firebox means and secured to the bottom plate, including
- outer front wall means,
- first and second outer side walls spaced apart from each other and secured to the outer front wall means,
- an outer back wall spaced apart from the outer front wall and secured to the outer side walls;
- a top plate secured to the outer wall means;
- a plurality of first heated air chambers between the firebox means and the outer wall means through which air flows;
- plenum chamber means including a plenum chamber disposed between the floor plate means and the bottom plate and the outer wall means and communicating with the plurality of first heated air chambers for receiving the flow of air;
- secondary combustion chamber means including a primary settling chamber communicating with the firebox means for receiving a flow of particulate matter and gaseous products of combustion from the primary combustion chamber from the burning of fuel and for slowing the velocity of the flow of particulate matter and gaseous products of combustion to allow particulate matter to settle out of the flow;
- grid means comprising a plurality of grid tubes extending from the firebox means to the secondary combustion chamber means through which the particulate matter and gaseous products of combustion flow for providing heat for combustion of particulate matter and gaseous products of combustion;
- a secondary settling chamber communicating with the secondary combustion chamber means for the settling of particulate matter from the flow of particulate matter and gaseous products of combustion;
- damper chamber means disposed above the secondary settling chamber through which the flow of particulate matter and gaseous products of combustion flow and comprising a tertiary settling chamber for particulate matter;
- flue means communicating with the damper chamber means for receiving the flow of gaseous products of combustion and any particulate matter therein not settled out in the settling chambers and for transporting the flow out of the furnace fireplace apparatus;
- and
- outer stack means disposed about the flue means and including a second heated air chamber through which the air flows and communicating with the plurality of first heated air chambers.

Apparatus for producing heat from burning fuel comprising, in combination:
- combustion chamber means, including a front wall, a rear wall, a first and a second side wall, a floor, and a ceiling for burning fuel;
- primary settling chamber means disposed adjacent the combustion chamber and communicating therewith for receiving a flow of combustion gases and products of combustion from the burning of fuel in the combustion chamber in which heavier unburned products settle out of the flow of combustion gases and products of combustion;
- passage means extending between the combustion chamber means and the settling chamber means through which the combustion gases and products of combustion flow and disposed adjacent the ceiling of the combustion chamber for providing a vertically upward flow of the said gases and products from the combustion chamber and a vertically downward flow of the gases and products from the passage means into the primary settling chambers means;
- secondary settling chamber means disposed adjacent and communicating with the primary settling chamber means for receiving the flow of combustion gases and products of combustion from the primary settling chamber means in which lighter unburned products of combustion settle out of the flow of combustion gases and products of combustion;
- damper chamber means disposed above the secondary settling chamber means for receiving the flow of combustion gases and products of combustion from the secondary settling chamber means and comprising a tertiary settling chamber in which the lightest unburned products of combustion settle out of the flow of combustion gases and products of combustion, and including
- a damper opening between the secondary settling chamber means and the damper chamber means, and
- an adjustable damper adjacent the damper opening and movable to control the flow of combustion gases and products of combustion from the secondary settling chamber means to the damper chamber means;
- chimney flue means communicating with the damper chamber means for receiving the flow of combustion gases and products of combustion from the damper chamber means and for conducting them out of the apparatus;
- wall means disposed about the combustion chamber means and comprising a plurality of panels defining the outer walls of the apparatus;
- and
- heated air chamber means disposed between the combustion chamber means and the wall means through which air flows for receiving heat from the combustion of fuel in the combustion chamber means.
