目前,提高隔热保温墙砖的孔隙率已受到了限制,这是由于原料中有机物是在预热带很小的温度范围内就燃烧完了,同时还释放了许多能量,有时还导致隧道窑处于难以控制的状态。在一个研究项目的框架内,HansLingl公司开发了一项焙烧技术,当焙烧富含能量的原料时,能保证焙烧工艺的安全运行。下面介绍这种焙烧技术。 Nowadays, increasing the porosity of thermal insulation wall tiles has been limited because organic materials in the raw materials burn out in a very small temperature range of the preheat zone, and at the same time release a lot of energy and sometimes cause the tunnel kiln to be in Uncontrollable state. Within the framework of a research project, HansLingl has developed a roasting technology that ensures the safe operation of the roasting process when roasting energy-rich raw materials. The following describes the roasting technique.
