METHOD OF MANUFACTURING HEAT-INSULATING MINERAL WOOL PRODUCTS

摘要

FIELD: chemistry.SUBSTANCE: uniform mixing of raw materials and fuel is carried out before loading into a melting furnace. Melting of the mineral charge is realised by means of heated atmospheric air, pumped into a tubular recuperator and directed for burning into the furnace with its enrichment with oxygen. Smoke gases from the furnace are directed to additional heating into a chamber for after-burning to 650-700°C and then into the tubular recuperator, where heat-exchange with atmospheric air takes place. After output from the recuperator the smoke gases are directed into a chamber of mineral wool carpet polymerisation to supply in it a required temperature mode.EFFECT: increase of fuel burning intensity with the extension of the melting zone with the economy of fuel for melting the initial raw material and polymerisation of the mineral wool carpet.1 dwg
