| 摘要 |
<p>The present invention concerns a method for melting recycled silicate starting materials (70), wherein a rotating transport flow (54) comprising helical flow filaments of transport air (66) and starting material (70) is supplied in the direction of the helix axis (72) thereof into the combustion chamber (8) of a cyclone furnace. Preferably pre-heated fresh air is used which is supplied partly into the combustion chamber (8) as combustion air therefor and partly in the form of the transport air (66). The present invention furthermore concerns a device for melting recycled silicate starting materials (70). The device includes a combustion chamber (8) wherein fuel (18) and combustion air (22) can be burnt up in the presence of the starting material (70). A forechamber (38) is arranged between an admixer (56) for generating an injector flow (50) and the combustion chamber (8). The injector flow (50) can be supplied into the forechamber (38) through a charging conduit (48) to generate a transport flow (54) made up of starting material (70) and transport air (66). The forechamber (38) comprises an outlet port (36) opening into the combustion chamber (8).</p> |
