德国西卡斯雷文斯大学(Case Western Reverst University)对各种燃气熔铝炉的热损失(meltingloss)及热效率研究见下表。热损失主要是烟气带走的、开启炉门散失的与炉墙散失的,因此回收烟气中的热、减少炉门开启次数、增强炉墙保温性能是提高热效率的主要措施。炉型熔化损失(mel Case Western Reverst University, Germany The heat loss (meltingloss) and thermal efficiency of various gas-fired aluminum furnaces are summarized in the following table. Heat loss is mainly taken away by the flue gas, which is dissipated from the furnace wall and dissipates from the furnace wall. Therefore, it is a major measure to increase the thermal efficiency by recovering the heat from the flue gas, reducing the number of door openings and increasing the thermal insulation performance of the furnace wall. Furnace melting loss (mel
