摘要： A method of destructing mineral-wool scrap and reusing the scrap in the manufacture of mineral wool includes introducing the mineral-wool scrap in a finally divided state into a container causing the finely-divided mineral-wool scrap to pass through a heating zone generated by an oxygen burner such as to convert the mineral-wool scrap to a liquid state and delivering the molten mineral-wool scrap into a furnace in which a melt for manufacturing mineral-wool is produced or to an intermediate container mounted between the furnace and a spinning machine. When the molten mineral-wool scrap is being delivered to the intermediate container, molten material taken from the furnace is also delivered to the intermediate container.

摘要： A method for reducing the flame temperature of an oxy-fuel burner, such a burner comprising a central oxygen nozzle at least one fuel nozzle radially spaced from the central oxygen nozzle, and at least one peripheral oxygen nozzle at greater radial distance from the central oxygen nozzle than the fuel nozzle, all nozzles being at least substantially parallel, a casing surrounding the nozzles and whose forward end lies in a plane at right angles to the longitudinal axis of the burner, and whose rear portion defines an oxygen chamber, and means for the supply of oxygen-containing gas and fuel, respectively, to the nozzles. The peripheral oxygen nozzle is in the form of a Laval nozzle or, if it is an annular nozzle, is of the same cross-sectional variation as the Laval nozzle throughout its entire length. The major fraction of the volume of oxygen requisite for combustion is caused to pass at great speed through at least one oxygen nozzle disposed about the burner nozzle and thereby aspirate ambient atmosphere which is at a lower temperature than the flame, before the oxygen from the oxygen nozzle reacts in the flame.
