Abstract: In a method of this invention, a first oxidant flow including oxygen and/or air, is injected into an exhaust gas flow from a primary burn zone in a furnace combustion chamber. The first oxidant flow is injected into the exhaust gas flow in a secondary burn zone downstream from the primary burn zone, but inside of the furnace chamber so that heat released from combustion of the first oxidant flow can be used for the purpose to which the furnace is applied. Also, the injection of the first oxidant flow into the secondary burn zone combusts fuel pollutants that might otherwise be released from the furnace into the atmosphere. The method can also include mixing a gaseous hydrocarbon fuel flow with the exhaust gas flow from the secondary burn zone to reduce the NO.sub.x, level in the exhaust gas. Also, the method can include mixing a second oxidant flow including air and/or oxygen, with the exhaust gas, preferably after reducing the NO.sub.x. If the furnace is a regenerative type, the air flow can be mixed with the exhaust gas flow in proximity to the entrance of a regenerator to heat the regenerator. The invention also includes a related system.

Abstract: In a firing installation which is designed to minimize the pollutant emissions during the use of both a liquid and a gaseous fuel, an annular chamber (12) is arranged downstream of a first combustion stage (1) on the head side of a second combustion stage (2) arranged downstream. The first combustion stage (1) is operated as a lean stage with a burner (100), while the second combustion stage (2) is operated as a near-stiochiometric stage. The wall of the annular chamber (12) has a number of openings (13) for the inflow of a mixture (14) of recycled flue gas (4) and fuel (15). The combustion air (115) for the burner (100) is likewise a mixture (6) of air (3) and recycled flue gas (4). The hot gases from this first combustion stage (1) are moderated before entering the second combustion stage (2), self-igniting combustion taking place in this second combustion stage (2) starting from the annular chamber (12).

The second air inlet is positioned closer to the front of the barrel than the first air inlet, and air at a second flow rate is deliverable at the second air inlet from the secondary air link and into the combustion chamber. A slag trap is operatively connected to the barrel so as to be able to receive slag generated from combustion of the fuel in the barrel, and the slag trap is closer to the back than the second air inlet.
