A combustion system for burning firewood including a combustion chamber defined by front, rear and side walls, a ceiling and a bottom. An access door is provided for addition of fuel into the combustion chamber. A substantial amount of combustion air enters the combustion chamber near the top of the fueling doors via apertures and is directed down the face of the fueling doors providing cooling. A geometry of the air metering orifice is either fixed or of limited adjustability such that the minimum flow of combustion air required for flaming combustion of a full load of fuel is maintained at all times. The combustion air flow cannot be reduced beyond a certain point and thus smoldering and very low air / fuel ratios are avoided. Since the air metering is tuned for proper flaming combustion with the largest expected fuel load and cannot be reduced further, fuel loads smaller than the design fuel load will result in higher air / fuel ratios, thus further ensuring that sufficient combustion air is present for sustained flaming. Furthermore, the minimum combustion air setting limits the amount of combustion air entering the combustion chamber such that too much air is not introduced resulting in inefficiency due to sensible heat loss, chemical loss (pollution), quenching of the flames, and undesirably high burn rates. Ideally, the burning rate of a full load of fuel is below 5 kg / hr, however, the maximum bum rate when burning a full load of fuel may be reduced to as low as 2 kg / hr depending on the size of the firebox and the desired maximum heating capacity of the appliance. Heat output is adjustable primarily by the amount of fuel added at each fuel loading.
