Method of operating a firing installation |
摘要 |
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).
