METHOD OF CONTROLLING THERMAL AND TECHNOLOGICAL PROCESS OF GLASS MELTING IN BATH FURNACES FOR PRODUCING SHEET GLASS BY FLOATATION METHOD

摘要

FIELD: chemistry.SUBSTANCE: total thermal load of 66-69% of the overall thermal load is set on a five-burner furnace at the first three burners of the furnace over the melting zone with the same thermal load at each of the three burners of 22.5±0.5%. As a result, the temperature maximum in the gaseous media is set in region of the third burner, the hotspot approaches the mixture melting zone and total thermal load of 31-34% of the overall thermal load on the furnace is set in clarification and homogenisation zones. The difference between temperature in the gaseous medium at the end of the melting tank of the furnace and at the beginning of the mixture melting zone before the first burner is kept at 10±5°C. The invention enables to completely automate the melting process. Power consumption is 1400-1500 kcal per kg of the molten glass mass. The operating period of the furnace is 10-12 years. Output of high-grade sheet glass increases by 8-10%.EFFECT: low power consumption of the melting process, longer life of the furnace and high quality of the product.2 dwg
