The Effect of Flame Length on Exterior Heat Exchange in a Glass Melting Furnace with Horseshoe-Shaped Flame

The topicality of studying heat and mass exchange in a glass-melting furnace with horseshoe-shaped flame is substantiated. The main requirements on advisable flame length in this type of furnace are formulated. The need for jointly solving the exterior and interior heat-transfer problems is demonstrated. The results of calculating temperatures of the gaseous medium, the roof, and the glass melt surfaces depending on the flame length are given. It is established that based on the set of conditions, the recommended length of the flame can be taken equal to the furnace length. The extent of the intense combustion zone (visible part of the flame) in this case is approximately 0.7 furnace length.
