摘要： The disclosure relates to a method of generating a powerfully oxidizing flame, and a burner therefore, the burner including a central body (9) with a central oxygen nozzle (23) and at least one fuel nozzle (25, 26), a casing (1) surrounding the central body (9), at least one peripheral oxygen nozzle (13) radially outside the fuel nozzle (25, 26), and an oxygen chamber (21) outside the central body (9), all nozzles (23; 25, 26; 13) being at least substantially parallel. The central oxygen nozzle (23) and the peripheral oxygen nozzle (13) are connected to different sources of oxygen, it being possible for the source connected to the central oxygen nozzle (23) to deliver a higher pressure than the other source. Preferably, the central oxygen nozzle (23) is designed as a laval nozzle. When solely oxygen is supplied to the burner, it may be employed as an oxygen lance. Preferably, oxygen is then only supplied to the central oxygen nozzle (23).

摘要： The invention relates to a method of destructing mineral-wool scrap and re-using the scrap in the manufacture of mineral wool. The method is characterized by introducing the mineral-wool scrap into a container in a finely-divided state, and causing the finely-divided scrap to pass through a heating zone generated by an oxygen burner. The mineral-wool scrap is converted to a liquid state in the heating zone and the molten scrap is then introduced to a molten bath produced in a furnace for the manufacture of mineral wool, or to an intermediate container which is mounted between the furnace and a spinning machine. Molten material taken from the furnace is also delivered to the intermediate container. The invention also relates to an arrangement for destructing mineral-wool scrap and re-using the scrap in the manufacture of mineral wool. This arrangement includes a container (20, 31), at least one oxygen burner (25) mounted in the container wall (24; 33, 34) and functioning to melt the mineral-wool scrap, at least one conduit (21) for removing molten mineral-wool scrap, this conduit (21) connecting the container (20, 31) with a furnace (200) intended for the manufacture of mineral wool, or to an intermediate container (40) mounted between the furnace (200) and a spinning machine.

摘要： A method and a burner for combusting fuel with oxygen, the fuel being delivered to a combustion zone from a center exit nozzle (5). Oxygen travelling at low speed is delivered from a first oxygen nozzle (3) at a first radial distance from the center fuel jet, and oxygen travelling at high speed is delivered from a second oxygen nozzle (6) at a second, greater radial distance from the center fuel jet. This results in incomplete combustion of the fuel with the oxygen moving at low speed in a first region, and incomplete combustion with the oxygen moving at high speed in a second region downstream of the first region, these regions together forming the combustion zone.

摘要： Method for reducing the flame temperature of an oxy-fuel burner, such a burner comprising a central oxygen nozzle (15) at least one fuel nozzle (17) radially spaced from the central oxygen nozzle (15), and at least one peripheral oxygen nozzle (2) at greater radial distance from the central oxygen nozzle (15) than the fuel nozzle (17), all nozzles (15, 17, 20) being at least substantially parallel, a casing (4) 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 (8, 7) for the supply of oxygen-containing gas and fuel, respectively, to the nozzles. The peripheral oxygen nozzle (20, 120) is in the form of a Laval nozzle or, if it is an annular nozzle, is of the same cross-sectional variation as a 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.
