    摘要: Fuel such as coal is combusted in a staged combustion device in a method comprising feeding into a first combustion stage of said furnace said fuel and gaseous oxidant containing more than 21 vo. % oxygen, and preferably 21.8 to 29 vol. % oxygen, at a stoichiometric ratio below that which, if the stage were operated with air as the only oxidant, would produce the same amount of Nox, and combusting said fuel with said gaseous oxidant in said combustion stage to produce combustion products and unburned fuel.

    摘要: In a furnace such as a glassmelting furnace, a portion of the combustion products formed by combustion of fuel with gaseous oxidant within the furnace are passed through a recuperative or regenerative heat exchanger system to heat a portion of the incoming gaseous oxidant, and a portion of the combustion products are passed instead through a secondary heat exchanger system, wherein the hot combustion products and oxidant which are passed through said first heat exchanger are passed at a heat capacity rate ratio of combustion products to oxidant of less than 1.3.
