Japanese Patent JP3655630
Kind Code:
B2
Abstract:
PCT No. PCT/EP94/02526 Sec. 371 Date Jul. 21, 1995 Sec. 102(e) Date Jul. 21, 1995 PCT Filed Jul. 29, 1994 PCT Pub. No. WO95/04003 PCT Pub. Date Feb. 9, 1995The melting tub for producing the molten mass from a mixture of raw material is associated with an additional melting unit by means of which a recycled molten mass is obtained from mineral wool waste largely corresponding to the molten mass obtained from the mixture of raw materials in quality and composition. The recycled molten mass is supplied to the molten mass in the melting tub through a suitable introduction device. The recycling exhaust gas from the additional melting unit is fed to the tub exhaust gas, and the mixture of exhaust gas is utilised for pre-heating combustion air and mixture of raw materials. Due to dividing "preparation of molten mass" into conventional production of molten mass from the mixture of raw materials in the melting tub and concurrent production of molten mass from mineral wool waste in an additional melting unit, molten products and exhaust gas of which are directly supplied to the melting tub, it is possible to utilise mineral wool waste as a recycled starting material in a cost-effective manner without affecting the complicated control of process parameters in conventional production of molten mass.
