烧制发泡陶瓷用窑炉

Kiln for Firing Foamed Ceramics

当前,我国累计堆存固体废弃物总量约为600~800亿吨。发泡陶瓷作为一种变废为宝、环保节能的绿色建材,它的产业化可以消耗大量堆存的固体废弃物。但由于生产工艺及关键设备的技术瓶颈,发泡陶瓷在大规格、高强度保温材料的烧成方面还没有完全突破。关键是新型大规格、高强度的发泡陶瓷用的窑炉产能还相对较低,烧成能耗仍较高。不论辊道窑或是隧道窑均有发展空间,所以本文重点概述了烧成发泡陶瓷用的两种窑炉的研究现状及发展前景。

At present,the total amount of solid waste in China is about 60-80 billion tons.Foamed ceramics is a kind of green building material which can turn waste into treasure,which can protect environment and save energy.Its industrialization can consume a large amount of solid waste.However,due to the technical bottleneck of production process and key equipment,the firing of foamed ceramics in large-scale and high-strength insulation materials has not been completely broken through.The problem is that the kiln productivity of new large size and high strength foamed ceramics is relatively low,and the energy consumption of firing is still high.Whether roller kiln or tunnel kiln has room for development,so this paper mainly outlines the research status and development prospects of two kinds of kilns for firing foamed ceramics.
