20080227040 | Method and Installation for Unsupported Lean Fuel Gas Combustion, Using a Burner and Related Burner - The invention concerns a method for a lean gas combustion using at least one burner including a combustion nozzle on a central axis (x). The method includes creating a mixture of fuel gas and combustion air rotating about the central axis, and ejecting a flow of non-flammable premix containing a mixture of premix air and fuel gas in front of the combustion nozzle. A complementary flow achieves a non-flammability threshold of the mixture in front of the combustion nozzle, the flow being ejected at the center of the premix flow via a central complementary flow and/or about the premix flow via a peripheral complementary flow. The invention also concerns a burner configured to implement the method and a combustion installation using same. | 09-18-2008 |
