OPTIMIZATION PROGRAM FOR BATCH WETTING OFFERS BENEFITS IN FURNACE LIFE, ENERGY EFFICIENCY, AND OPERATIONAL RELIABILITY

摘要

This present paper highlights the results of applications of Dry Batch Optimizer (DBO) technology in the container glass industry. The authors will discuss proper use of this technology to aid in the effectiveness of batch wetting, allowing glass manufacturers to take full advantage of the benefits of batch wetting while minimizing or eliminating its drawbacks. Pre-wetting of batch material prior to its addition to the furnace is a common practice, and most glass manufacturers agree on its benefits: reduced dusting inside and outside the furnace, extension of furnace life, reduced fouling of regenerators, and better control of particulate emissions from the furnace. Nalco has now documented information showing that we can achieve additional benefits such as: improved homogeneity of the batch mixture, reduction of excess moisture and associated energy benefits, improved batch pile shape and resulting melting efficiency leading to additional energy savings, improved cleanliness of mixers with reduced torque / wear and tear, and finally, improved safety resulting from reduced dusting as well as reduced need for operator intervention to clean the batch feed system.
