Abstract

The design features and operating parameters of a cupola-based equipment complex developed by the Italian company “Gamma Meccanica” are analyzed in connection with the increasing use of this equipment in the production of heat-insulating mineral-wool products. The limitations of the injection system are discussed and it shown that the main physico-chemical, gasdynamic, and thermal processes which take place are quite nonuniform, which restricts the maximum productivity of the complex to 6 tons/h and limits its overall thermal efficiency to 11.78%.
