    摘要: Method for homogenizing the heat distribution as well as decreasing the amount of NOx in combustion products when operating an industrial furnace with at least one conventional burner using air as an oxidant. An additional oxidant including at least 50% oxygen gas is caused to stream into the furnace through a lance. The total amount of oxygen supplied is balanced against the amount of fuel being supplied through the air burner. Firstly, the combination of at least 40% of the supplied oxygen is supplied through the additional oxidant, the lance is arranged at a distance from the air burner of at least 0.3 meters, and the additional oxidant streams into the furnace through the lance with at least sonic velocity, and secondly the additional oxidant is supplied only when the air burner is operated at a certain lowest power or at a higher power.

    摘要: A method and an apparatus for heat-treatment of materials, preferably metals, are provided. The method comprises the following steps: providing and maintaining a flame by supplying a burner with fuel and gas containing at least 80 percent by volume oxygen; creating an oxygen-hot exhaust mixture by recirculating exhausts from the flame to the gas containing oxygen by means of an ejector effect; mixing the oxygen-exhaust mixture and the fuel; and providing a secondary recirculation by recirculating exhausts from the flame to the oxygen-exhaust-fuel mixture. The method and apparatus allow for extremely low NOx emissions and high efficiency, resulting in an environmentally friendly and at the same time cost effective process.

    摘要: A method and apparatus relating to the combustion of a fuel with an oxidant in a heating furnace, wherein the fuel and the oxidant are delivered to a burner head. In a first method step fuel and oxidant are emitted from the burner head in close proximity to each other, so that combustion essentially takes place close to and at a small distance outward of the burner head, and until a temperature is reached in the furnace space that exceeds the spontaneous combustion temperature of the fuel. In a second method step the fuel and the oxidant are instead emitted from the burner head at a mutual distance apart, so that combustion takes place at a distance from the burner head corresponding to at least the diameter of the burner head and outward of the burner head.

    摘要: A seal for burners for the combustion of fossil fuels with an oxidant gas that contains a high fraction of gaseous oxygen. The burner includes a burner body with a cylindrical opening within which a cylindrical nozzle is removably positioned. The nozzle includes axial channels for the supply of fuel and oxidant gas. One, two or more parallel annular grooves are provided in the outer peripheral surface of the cylindrical nozzle. Each groove is arranged to support a sealing ring that is split or discontinuous at one location along its periphery. Each ring is arranged to lie in contact with the inner surface of the cylindrical opening when the nozzle is mounted in the burner body, with the discontinuities of the rings circumferentially offset relative to each other.
