摘　　要：硼氧化物(B2O3)自玻璃熔窑烟气中排放,与空气中的水反应生成硼酸产生酸雨,对环境造成了污染。烟气中高浓度的B2O3会造成烟气露点较高,使除尘器结露、糊袋,增大工程处理难度。玻璃熔窑高硼烟气处理成为研究热点。本文针对含硼烟气源头减量技术、处理干扰因素和处理技术进行分析,综合各技术去除效果、操作的难易度及经济性,推荐余热发电、半干法除氟和除硼化物组合工艺为目前富氧燃烧玻璃熔窑高硼烟气处理工程化应用的方向。Boron trioxide component will be contained in an exhausted gas from a glass melting furnace and it can be combined with wanter in air to product acid rain which will be a cause for air pollution. It is known B203 is one of the most difficult compounds to crystallize, and it causes the dew point of flue gas at high temperature, easily to produce condensation phenomenon in bag filter and increasing engineering treatment difficulty. Influence of particulates in the flue gas, operation requirements and economics of these De-B technologies were also compared. The combined process of waste heat power generation, dry cleaning system with F treatment and the purifications of boron trioxide using bag filter are recommended as the potential treatment technologies of flue gases containing boron compounds for full scale application.
