我厂依靠自己的力量,将原设计133m~3砖质干燥炉修改设计成182m~3全纤维干燥炉,并顺利投产。实践表明,该炉结构合理具有升温快、炉温均匀、温差小等特点。由于该炉采用了全纤维结构,在原有的础基上,扩大了容积,提高了砂型产量,大大减少了炉子蓄热损失。因而大幅度的提高了炉子热效率。据初步热工测试(燃煤气)热效率达45.5％。但该炉还存在一些问题:如燃烧装置等,有待今后解决。
I rely on our own plant, the original design 133m ~ 3 brick drying furnace modified into a 182m ~ 3 fiber drying furnace, and the smooth operation. Practice shows that the furnace structure with reasonable temperature fast, uniform temperature, temperature and other characteristics. As the furnace with a full fiber structure, in the original foundation, expanding the volume and improve the sand production, greatly reducing the furnace heat storage loss. Thus greatly improving the thermal efficiency of the stove. According to preliminary thermal test (gas) thermal efficiency of 45.5%. However, the furnace still has some problems: such as burning devices, to be solved in the future.
