摘要
总结了具有百年历史的蓄热式窑炉具有的优势和劣势,论述了蓄热室不可替代的功能和提高热回收利用遭遇的技术瓶颈,以理论的最高回收率84%为目标,以作者的蓄热-换热组合式玻璃池窑专利为手段,可将现实的蓄热室的空气预热温度由近1 000℃提高到1 250℃,烟气热能回收率由52.6%提高到65.8%,。以"七五"攻关544 t/d窑为例,可节省渣油3515 t/a,达到投资最小而烟气热能资源化率最大化,为节能减排、增产降耗提供了有力的技术支撑。
Summarized the advantages and disadvantages of regenerative furnace that has 100 years history; discussed the irreplaceable function of regenerator and its technical bottle neck encountered during the improvement of energy recycling; set the target of as 84% as the highest recovery in theory. With the method described in author's patent of regenerative-recuperative combined float glass furnace, the current pre-heating temperature of air entering the regenerator can be increases from 1000℃ to 1250℃. The heat recovering rate from flue gas can be improved from 52.6% to 65.8%. Take the example of the 544t/d furnace built in "Qi Wu" Gong Guan project, we can save residue oil 3115 t/a. This can maximize flue gas resource usage with minimum investment. It provides a strong technical support for energy saving, omission reduction, production improvement and consumption reduction.
