| description | Method for heating a furnace (100), arranged with a heating zone (120) heated using a burner (122) providing a flame extending in a longitudinal direction (D) and fed with a fuel and a primary oxidant. The invention is characterised in that the burner is operated with a mass relationship between the fed fuel and primary oxidant permitting less than 50% of the fed fuel to be combusted using the primary oxidant, in that a respective pair of secondary oxidant lances (151,152;153,154) are provided one either side of the furnace pointing into the heating zone, lancing a secondary oxidant into the heating zone downstream of the said burner, substantially in parallel with a cross plane (C), in that the temperature is measured downstream of the said lances, in that each of the lance pairs comprises an upstream, low-speed first and a downstream, high-speed second lance, and in that the amount of secondary oxidant supplied via the first lance is regulated to achieve a homogenous lateral temperature profile. The invention also relates to a furnace. |
