    摘要: Method for measuring the local temperature in an industrial furnace (1) equipped with a burner (3), where at least two temperature sensors (21, 22) are arranged at different locations in the furnace (1). A virtual temperature measuring point is created by the association of each temperature sensor (21, 22) with a certain weight factor, in that the measurement values from each temperature sensor (21, 22) are weighted together using these weight factors in order to thus achieve a virtual measurement value, in that the weight factors at every given point in time are individually controlled based upon the momentarily emitted power of the burner (3), and in that the virtual measurement value in turn constitutes control parameter for the control of the emitted power of the burner (3).

    摘要: Method for combustion of a fuel uses an existing air burner (1), including a first supply opening (5) for fuel and a second supply opening (7) for air, which supply openings (5, 7) open out into a combustion zone (3). The method is characterised in that a gaseous fuel with an LHV (Lower Heating Value) of less than 7.5 MJ/Nm3 is supplied through the second supply opening (7), in that an oxidant including at least 85 percent by weight oxygen is also supplied to the combustion zone (3) through a supply device for oxidant, and in that the gaseous fuel is caused to be combusted with the oxidant in the combustion zone (3).

    摘要: A method for heating a metal slab being transported in a longitudinal direction (L) and having a cross-direction (T) through an industrial furnace in which the metal slab is heated and transported on a rail device from the industrial furnace for subsequent processing, includes impinging a flame from at least one direct flame impingement (DFI) burner to contact a first portion of a first surface of the metal slab in at least one location corresponding to a second position on an under side surface of the metal slab which during transporting of the metal slab through the industrial furnace constitutes a contact point between the under side surface of the metal slab and the rail device, and counteracting a temperature gradient in the metal slab arising from local cooling of the metal slab upon contact with the rail device by heating the first portion with the DFI burner.

    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: Method for combusting a solid phase fuel, where the fuel is caused, by the help of a non-pneumatic feeding element (11), to be fed to an inlet opening (11a) in a burner device (10) having a first inlet (13a) for the oxidant through which an oxidant is caused to flow via a first supply conduit (13). The first inlet (13a) for oxidant is caused to be arranged in the form of an opening surrounding the inlet opening (11a), in that the oxidant is caused to flow out through the opening (13a) with a velocity of at least 100 m/s, through a burner pipe (16) and out through a burner orifice (17) to a combustion space (18), so that the oxidant by ejector action causes the fuel to be conveyed through the burner pipe (16) and out through the burner orifice (17).
