Current State and Future Prospects for Improvement of Mineral Melt Production Technologies

The article outlines the production of fibrous materials, discloses energy production targets for mineral wool items production, scrutinizes specific features of cupola process. Besides, the article presents the experimental research of mineral wool cupola process. Thus, the article describes the design of a cupola furnace, principles of its operation, and its main performance indicators. A summary of analytical and theoretical research of non-isothermal gas flow motion in shaft furnaces is presented herein. The results of the experimental studies of the patterns of change in gas-dynamic operation of the cupola furnace are also shown in the article. To assess the development of solid fuel combustion in the furnace, the laws that govern the changes in gas composition at the level of stockline have been studied. The results are shown in the Table. The analysis of the current state of thermal and gas-dynamic operation of the mineral wool cupola furnace yielded recommendations for optimization and performance enhancement of the operating cupola furnace.
