PREHEATING OF MIX IN PRODUCTION OF MINERAL WOOL FIBRES FROM ROCKS AND DEVICE TO THIS END |
| 摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to production of mineral wool. Mix is preheated to 300-400°C in service hopper by off gases. Gases are fed by high-pressure blower via gas duct to flue gas distribution structure. The latter is arranged at the hopper bottom part and composed of crossed perforated pipes protected by V-like plate made from steel angle piece with 45 degrees-angle.EFFECT: higher efficiency of slag melt smelting.3 cl, 1 dwg |
