摘要： 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).

摘要： The melting tub (1) for producing the molten mass (2) from a mixture (21) of raw materials is associated with an additional melting unit (4) by means of which a recycled molten mass (29) is obtained from mineral wool waste (28) largely corresponding to the molten mass (2) obtained from the mixture (21) of raw materials in quality and composition. The recycled molten mass (29) is supplied to the molten mass (2) in the melting tub (1) through a suitable introduction device (43). The recycling exhaust gas (30) from the additional melting unit (4) is fed to the tub exhaust gas (24), and the mixture of exhaust gas is utilised for pre-heating combustion air and mixture of raw materials (21). Due to dividing 'preparation of molten mass' into conventional production of molten mass from the mixture (21) of raw materials in the melting tub (1) and concurrent production of molten mass from mineral wool waste (28) in an additional melting unit (4), molten products and exhaust gas of which are directly supplied to the melting tub (1), it is possible to utilise mineral wool waste (28) as a recycled starting material in a cost-effective manner without affecting the complicated control of process parameters in conventional production of molten mass.
