| 摘要 |
A method of minimizing the production of SOx and NOx in the burning of a fuel containing significant amounts of SOx and NOx precursors in which the fuel is treated to remove significant amounts of SOx precursors without the removal of significant amounts of NOx precursors and the fuel is thereafter burned in a two-stage, rich-lean burning step in which significant amounts of the NOx precursors are converted to N2. Treating the fuel to remove SOx precursors is preferrably carried out in the presence of an oxidizing agent, such as H2O2, a reducing agent, such as hydrogen, and/or steam, and still more preferably, the oxidizing agent, the reducing agent and steam are generated by burning an auxiliary fuel and passing the effluent thereof to the step of treating the fuel to remove SOx precursors.
